Latest View of Hurricane Joaquin

Hurricane Joaquin continued to intensify in the Bahamas on October 1 and NASA and NOAA satellites have been providing valuable data on the storm. NASA's GPM and Terra satellites and NOAA's GOES-East satellite provided rainfall, cloud extent, cloud height and other data to forecasters. Joaquin became a major hurricane today, October 1, reaching Category 3 status on the Saffir-Simpson Wind Scale. On October 1 at 1330 UTC (9:30 a.m. EDT) NOAA's GOES-East satellite captured this visible image of Hurricane Joaquin covering the southern Bahamas and extending over southeastern Cuba, and the island of Hispaniola (which includes Haiti and the Dominican Republic). Joaquin's eye had become completely visible now that the storm had reached Category 3 status. On October 1, a Hurricane Warning was in effect for the Central Bahamas, Northwestern Bahamas including the Abacos, Berry Islands, Eleuthera, Grand Bahama Island, and New Providence, The Acklins, Crooked Island, and Mayaguana in the southeastern Bahamas. A Hurricane Watch was in effect for Bimini and Andros Island, and a Tropical Storm Warning was in effect for the remainder of the southeastern Bahamas excluding the Turks and Caicos Islands and Andros Island. According to NHC, at 8 a.m. EDT (1200 UTC), the center of Hurricane Joaquin was located near latitude 23.2 North, longitude 73.7 West. That's just 10 miles (15 km) north of Samana Cays, Bahamas and about 75 miles (120 km) southeast of San Salvador, Bahamas. Joaquin was moving toward the west-southwest near 5 mph (7 kph), and this motion is expected to continue today. NHC noted that a turn toward the west- northwest is forecast tonight (Oct. 1), followed by a turn toward the north and an increase in forward speed on Friday, Oct. 2. On the forecast track, the center of Joaquin will move near or over portions of the central Bahamas today and tonight and pass near or over portions of the northwestern Bahamas on Friday. Maximum sustained winds are near 120 mph (195 km/h) with higher gusts. Joaquin is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some strengthening is forecast in the next day or so, with some fluctuations in intensity possible on Friday. Hurricane force winds extend outward up to 35 miles (55 km) from the center and tropical storm force winds extend outward up to 140 miles (220 km). The minimum central pressure just extrapolated by an Air Force Reserve Hurricane Hunter aircraft is 942 millibars.

Animation of Tropical Storm Joaquin right before it intensified into a hurricane on September 29, 2015

-- Joaquin became a tropical storm Monday evening (EDT) midway between the Bahamas and Bermuda and has now formed into a hurricane, the 3rd of the season--the difference is Joaquin could impact the US East Coast. GPM captured Joaquin Tuesday, September 29th at 21:39 UTC (5:39 pm EDT) as the hurricane moved slowly towards the west-southwest about 400 miles east of the northwestern Bahamas. At the time, Joaquin had been battling northerly wind shear, which was impeding the storm's ability to strengthen. However, compared to earlier in the day, the system was beginning to gain the upper hand as the shear began to relax its grip. At the time of this data visualization, Joaquin's low-level center of circulation was located further within the cloud shield, and the rain area was beginning to wrap farther around the center on the eastern side of the storm while showing signs of increased banding and curvature, a sure sign that Joaquin's circulation was intensifying. GPM shows a large area of very intense rain with rain rates ranging from around 50 to 132 mm/hr (~2 to 5 inches, shown in red and magenta) just to the right of the center. This is a strong indication that large amounts of heat are being released into the storm's center, fueling its circulation and providing the means for its intensification. Associated with the area of intense rain is an area of tall convective towers, known as a convective burst, with tops reaching up to 16.3 km (shown in orange). These towers when located near the storm's core are a strong indication that the storm is poised to strengthen as they too reveal the release of heat into the storm. At the time this data was taken, the National Hurricane Center reported that Joaquin's maximum sustained winds had increased to 65 mph from 40 mph earlier in the day, making Joaquin a strong tropical storm but poised to become a hurricane, which occurred this morning at 8:00 am EDT. With the inhibiting wind shear expected to continue to diminish and the system moving over warm waters, the National Hurricane Center is forecasting Joaquin to intensify further, possibly into a major hurricane within the next few days.

Evaporative Stress Index over San Joaquin Valley

The San Joaquin Valley, CA is one of the most productive agricultural regions in the United States and the world. The image shows the Evaporative Stress Index over the San Joaquin Valley on May 22, 2022 at 06:04 PM PDT where many fields show high ESI values that indicate low plant stress whereas low ESI values indicate high plant stress. ECOSTRESS's ability to detect Evaporative Stress over the agricultural fields can help farmers and decision makers in their choices. As California is in a continuing drought, it is important to monitor that agricultural plant life. ECOSTRESS is a thermal instrument on the International Space Station that measures the temperature of the ground, which is hotter than the air temperature during the day. It was launched to the space station in 2018. Its primary mission is to identify critical thresholds of water use and water stress in plants and to detect the timing, location, and predictive factors leading to plant water uptake decline and/or cessation. The nature of the high-resolution data provided by ECOSTRESS allows it to record heat related phenomena such as heat waves and wildfires. https://photojournal.jpl.nasa.gov/catalog/PIA25487

$The Sacramento-San Joaquin River Delta, CA (or California Delta) has an area of about 3000 km2, and provides a large fraction of all the water used in California. The Delta drains about 50% of the water coming from the Sierra Nevada Mountains, and channels it through San Francisco's Golden Gate to the Pacific Ocean. Thousands of miles of levees now carefully control the Delta's flow, to maximize water use. The image combines a false color infrared composite (with vegetation depicted in red) with a colorized thermal infrared band to show the water temperature for the larger water bodies.

Northern California near San Francisco

SL4-138-3843 (1 Jan. 1974) --- A part of northern California centered near San Francisco Bay photographed at 3 p.m. Jan. 2, 1974, from the Skylab space station in Earth orbit. This near vertical view encompasses the coastline from Monterey Bay (right) to about 50 miles north of Point Reyes (left) and includes, from bottom to top, San Francisco Bay (center), Sacramento Valley (left center), San Joaquin Valley (right center), and the snow-covered Sierra Nevada. Afternoon shadows sharply delineate a valley which parallels San Francisco Bay, crosses Point Reyes, and lies between the Bay and the Pacific coastline. This valley marks the location of the San Andreas Fault, a major break in the Earth's crust. Forces acting on the crust are causing the land west (bottom) of the fault line to move north relative to land on the east side. The Skylab 4 astronauts photographed major fault zones in South America, New Zealand, Japan and Africa for use in the study of worldwide tectonic system. Agricultural areas in the Sacramento and San Joaquin Valleys are indicated by the tan areas which are easily discerned in contrast to the green-gray background. Photo credit: NASA

Southern California as seen from the Apollo 7 spacecraft

This view of southern California as seen from the Apollo 7 spacecraft during its 18th revolution of the earth. Photographed from an altitude of 124 nautical miles. The coast of California can be seen from Point Mugu southward to Oceanside. Santa Catalina can be seen below the off shore clouds. Details of the Los Angeles area are obscured by pollution which extends from Banning westard for 100 miles to beyond Malibu. In the upper portion of the photograph can be seen (left to right) the San Joaquin Valley beyond Bakersfield, the Techachapi Mountains, the Sierra Nevada, Owens Valley, Death Valley and the Mojave Desert.

Exterior view of the ISS taken during a session of EVA

ISS028-E-016225 (12 July 2011) --- Components of the International Space Station, though moving along at 17,500 miles per hour, appear to hover above the Pacific Ocean just off the California coast. Ten cosmonauts and astronauts were working together when this photo was taken -- four of them as STS-135 visitors from the docked space shuttle Atlantis and six as members of the Expedition 28 crew. The Cupola, near center of frame, is attached to Node 3 or Tranquility. A Russian Soyuz and a Russian Progress spacecraft are parked at the station, left side of frame. While much of the coast is obscured by clouds, just inland from left to right, one can see the agriculture of the San Joaquin Valley, the southern Sierra Nevada, the Los Angeles Basin (center), the Mojave Desert, coastal mountains of southern California, the Salton Sea, the Imperial Valley, and the mouth of the Colorado River on the extreme right edge.

San Francisco Bay, California as seen from STS-59

STS059-213-009 (9-20 April 1994) --- San Francisco Bay. Orient with the sea up. The delta of the combined Sacramento and San Joaquin Rivers occupies the foreground, San Francisco Bay the middle distance, and the Pacific Ocean the rest. Variations in water color caused both by sediment load and by wind streaking strike the eye. Man-made features dominate this scene. The Lafayette/Concord complex is left of the bay head, Vallejo is to the right, the Berkeley/Oakland complex rims the shoreline of the main bay, and San Francisco fills the peninsula beyond. Salt-evaporation ponds contain differently-colored algae depending on salinity. The low altitude (less than 120 nautical miles) and unusually-clear air combine to provide unusually-strong green colors in this Spring scene. Hasselblad camera.

SL2-06-102

SL2-06-102 (June 1973) --- A black and white photograph of the San Francisco Bay California area, taken from the Skylab 1-2 space station cluster in Earth orbit. THE PICTURE SHOULD BE HELD WITH THE CLOUDS AND PACIFIC OCEAN ON THE LEFT. This photograph was taken by one of six lenses of the Itek-furnished S190-A Multispectral Photographic Facility Experiment in the Multiple Docking Adapter of the space station. Note the thickly populated and highly developed area around the Bay. Among the cities visible in this photograph are San Francisco, Oakland, Berkeley and San Jose.

Sierra Nevada, California

STS068-267-097 (30 September-11 October 1994) --- An extensive view eastward from the irrigated San Joaquin Valley in the foreground, across the Sierra Nevada (living up to its name in early October), into the desert of eastern California and Nevada (which has no snow, despite the name). Mono Lake is just visible at the left edge of the frame; Owens Valley extends southward to Owens Lake, the next valley is Panamint Valley, and then Death Valley. Las Vegas and Lake Mead are visible at the upper right of the frame. The Space Radar Laboratory 2 (SRL-2) obtained extensive, multiple-pass data from many test sites within the region displayed, including Mammoth Mountain ski area south of Mono Lake, and in Death Valley.

This anaglyph, from NASA Shuttle Radar Topography Mission, shows rugged terrain between Los Angeles and California central valley. 3D glasses are necessary to view this image.

Apollo 10 view of the Earth

AS10-34-5013 (18 May 1969) --- A view of Earth from 36,000 nautical miles away as photographed from the Apollo 10 spacecraft during its trans-lunar journey toward the moon. While the Yucatan Peninsula is obscured by clouds, nearly all of Mexico north of the Isthmus of Tehuantepec can be clearly delineated. The Gulf of California and Baja California and the San Joaquin Valley can be easily identified. Also, the delta of the Rio Grande River and the Texas coast are visible. Note the color differences (greens - east, browns - west) along the 100 degrees meridian. The crew members on Apollo 10 are astronauts Thomas P. Stafford, commander; John W. Young, command module pilot; and Eugene E. Cernan, lunar module pilot. Astronaut Young remained in lunar orbit, in the Command and Service Modules (CSM) "Charlie Brown", while astronauts Stafford and Cernan descended to within nine miles of the lunar surface, in the Lunar Module (LM) "Snoopy".

Earth observations taken during STS-98 mission

STS098-714A-020 (7-20 February 2001) ---One of the STS-98 astronauts aboard the Earth-orbiting Space Shuttle Atlantis used a 70mm handheld camera to record this image of Southern California. Snow blanketing the higher elevations in the Los Padres National Forest (center of the image) and that covering the Angeles National Forest (right middle) help to accentuate and separate three major landform regions in southern California. The northern Los Angeles Basin that includes the San Fernando Valley and the Santa Monica Mountains is visible in the lower right quadrant of the image. The western end of the Mojave Desert (upper right) shows the two distinctive mountain boundaries along the southwest and northwest edge of the desert. The San Andreas Fault and the Garlock Fault converge (snow covered in this scene) at the western end of the desert. The intensively irrigated and cultivated southern end of the San Joaquin Valley that includes Bakersfield is visible (upper left) north of the snow-covered, northeast-southwest trending Tehachapi Mountains. The island off of the California coast (bottom left) is Santa Cruz Island.

California topography poses challenges for road builders. Northwest of Los Angeles, deformation of Earth crust along the Pacific-North American crustal plate boundary has made transportation difficult.

Sierra Nevada Mountain Range as seen from STS-58

STS058-72-004 (18 Oct-1 Nov 1993) --- The Sierra Nevada Mountain Range can be seen in this north-looking high oblique view taken in October, 1993, by the STS-58 crew. Visible in the view to the west of the Sierra Nevada are the San Joaquin and Sacramento Valleys of central California. The San Francisco/Oakland Bay Area can be seen to the west of the valley at the extreme left of the photograph. To the east or right of the Sierra Nevada, the basin and Range Region of central and northern Nevada is visible. Mono Lake, Lake Tahoe and Pyramid Lake are also visible in this scene. The long northwest/southeast trending Walker Lane Shear Zone, which lies just to the east (right) of the Sierra Nevada is also visible. Near the top of the view (near the horizon), the snow covered volcanic peak Mount Shasta can be seen. Over 645 kilometers (400 miles) long and from 65 to 130 kilometers (40 to 80 miles) wide, the Sierra Nevada have many peaks in excess of 3,300 meters (11,000 feet) above sea level. A titled fault block in structure (the largest in the United States) and shaped by glaciers during the last ice age over 12,000 years ago, the Sierra Nevada eastern front rises sharply from the Great Basin of Nevada, while its western slope descends gradually to the hills bordering the Central Valley of California. Snow-fed streams supply much of the irrigation water to the Central Valley and to western Nevada and also generate hydroelectricity. Recent above normal precipitation (snowfall) of the last two years has helped in alleviating the drought conditions that had prevailed throughout most of California in the mid and late 1980's and early 1990's.

Declining Methane Emissions at California Oil Fields and Refineries

A March 2023 study by researchers at NASA's Jet Propulsion Laboratory in Southern California compared emissions from a belt of oil refineries across the South Bay area of Los Angeles during the first summer of the COVID-19 pandemic to those observed three years earlier. Using data from a NASA airborne instrument, researchers saw that most of the facilities they identified as methane sources in 2016-17 were no longer emitting the greenhouse gas in 2020, leading to a 73% reduction in measured emissions. The study uses measurements made by an imaging spectrometer called AVIRIS-NG (Airborne Visible/Infrared Imaging Spectrometer-Next Generation). Attached to the bottom of an aircraft, the instrument can detect greenhouse gas emissions from individual facilities or even pieces of equipment by looking at how the gases absorb sunlight. In 2016 and 2017, AVIRIS-NG was flown over 22,000 square miles (57,000 square kilometers) of the state as part of the California Methane Survey. From July to September 2020, researchers retraced some of those flight paths over refineries and power plants in Los Angeles County and over oil fields in central California's San Joaquin Valley. The flights were funded by NASA's Earth Science Division, the California Air Resources Board, and the California Energy Commission. The 2020 surveys over Los Angeles identified only 11 plumes from five refinery sources, with a total emissions rate of about 712 pounds (323 kilograms) methane per hour. The 2016 and 2017 flights had found 48 plumes from 33 sources, with a total emissions rate of roughly 2,639 pounds (1,197 kilograms) methane per hour. The drop correlates with an 18% decrease in monthly production in Southern California refineries between the two flight campaigns, the scientists noted, citing data from the California Energy Commission. The study also found that emissions from oil fields in and around the city of Bakersfield in central California fell 34.2%, correlating with a 24.2% drop in oil production. Reduced production during the pandemic due to lower demand for fuel and lower gas prices could have led to the drop in methane emissions, as oil fields and refineries emitted less methane as part of operations. However, researchers said, improved equipment maintenance and mitigation efforts at those facilities between 2016 and 2020 can't be ruled out as a factor. https://photojournal.jpl.nasa.gov/catalog/PIA25864
