NASA's RapidScat's antenna, lower right, was pointed at Hurricane Patricia as the powerful storm approached Mexico on Oct. 23, 2015. Patricia was the strongest hurricane ever recorded in the Western Hemisphere, with maximum winds of 200 mph (320 kilometers per hour). When it first made landfall on the Pacific coast of Mexico on Oct. 23, it was a destructive Category 5 storm. The videos are from the International Space Station. RapidScat's spinning antenna, lower right, collects wind-speed data from Hurricane Patricia. http://photojournal.jpl.nasa.gov/catalog/PIA20049

NASA ISS-RapidScat ocean wind scatterometer viewed Hurricane Ana as it approached Hawaii. From Oct. 13 to Oct. 19, 2014, RapidScat observed Ana seven times. This frame is from a movie containing multiple days of observation.
Launched Sept. 21, 2014, to the International Space Station, NASA newest Earth-observing mission, the International Space Station-RapidScat scatterometer to measure global ocean near-surface wind speeds and directions.

On Jan. 28, 2015 from 2:41 to 4:14 UTC, NASA ISS-RapidScat saw the noreaster strongest sustained winds red between 56 and 67 mph 25 to 30 mps/90 to 108 kph just off-shore from eastern Cape Cod.
NASA's ISS-RapidScat instrument on the International Space Station provided a look at the strong winds that led to coastal flooding in southern New Jersey during the historic winter storm that blanketed much of the U.S. East Coast, starting Jan. 23, 2016. At 2 a.m. PST on Jan. 23, RapidScat showed sustained winds as strong as 45 meters per second (100 mph/162 kilometers per hour) along the coast of southern New Jersey. Many beachfront towns in this region were flooded as winds pushed ocean waters inland. The town of Cape May, New Jersey, reported a flood level of 8.98 feet (2.74 meters) -- the highest on record. This image shows ocean winds near the surface off the U.S. East Coast, from the hook of Cape Cod at top center to the South Carolina coastline at bottom left. Southern New Jersey and the northern edge of Delaware are directly in the path of the highest wind speeds. http://photojournal.jpl.nasa.gov/catalog/PIA20366
NASA's ISS-RapidScat passed over Hurricane Patricia at about 3:00 AM GMT on Oct. 23, 2015. A Hurricane Warning was in effect from San Blas to Punta San Telmo. A Hurricane Watch was in effect from east of Punta San Telmo to Lazaro Cardenas and a Tropical Storm Warning was in effect from east of Punta San Telmo to Lazaro Cardenas. Patricia was moving toward the north-northwest near 12 mph (19 kph) and a turn toward the north is expected later this morning, followed by a turn toward the north-northeast this afternoon. On the forecast track, the core of Patricia will make landfall in the hurricane warning area today, Oct. 23, 2015, during the afternoon or evening. http://photojournal.jpl.nasa.gov/catalog/PIA20031

While El Niño events have a significant impact on the entire Earth System, they are most easily visible in measurements of sea surface temperature (SST), sea surface height (SSH) and ocean winds near the surface. In fact, the precursor and the main driver of El Niño events is manifested in the weakening of the normally westward blowing trade winds, or even their complete reversal to blow from west to east, in the Western and Central tropical Pacific. http://photojournal.jpl.nasa.gov/catalog/PIA20365

iss041e047260 (9/29/2014) --- A view of the removal of the RapidScat Nadir Adapter from the SpaceX-4 Dragon trunk and installation of the adapter onto the Columbus Exposed Facility Unit (EFU). ISS-RapidScat is a space-based scatterometer that replaces the inoperable SeaWinds payload aboard the QuickSCAT satellite. Scatterometers are radar instruments that measure wind speed and direction over the ocean, and are useful for weather forecasting, hurricane monitoring, and observations of large-scale climate phenomena such as El Niño. The ISS RapidScat instrument enhances measurements from other international scatterometers by cross-checking their data, and demonstrates a unique way to replace an instrument aboard an aging satellite.

Liftoff is targeted for an instantaneous window at 2:14 a.m. EDT. To learn more about the mission, visit http://www.nasa.gov/mission_pages/station/structure/launch/index.html.

The remnant moisture from what was once Hurricane Patricia and moisture from the Gulf of Mexico were being transported north by a trough of low pressure over Wisconsin. The clouds and moisture were streaming into the Eastern third of the U.S. on October 28, 2015. The hybrid system was generating windy conditions which were seen from NASA's RapidScat instrument, while NOAA's GOES-East satellite captured an image of the impressive and sizeable cloud cover.

Of all the planets NASA has explored, none have matched the dynamic complexity of our own. Earth is constantly changing, and NASA are working constantly to explore and understand the planet on scales from local to global. Though Earth science has been a key part of NASA’s mission since the agency was founded in 1958, this year has been one of the peaks. Two new Earth-observing satellites have already been launched and put to work: the Global Precipitation Measurement (GPM) and the Orbiting Carbon Observatory 2 (OCO-2). Three more missions are set to take off in the next six months: the wind-measuring ISS-RapidScat, the ISS Cloud-Aerosol Transport System (CATS), and the Soil Moisture Active Passive (SMAP). And research planes have been flying over polar ice, hurricanes, boreal forests, and pollution plumes. All of these new efforts complement an existing fleet of Earth-observing satellites. In visible light and many invisible wavelengths, NASA and its science partners are observing the entire planet every day. The image above was captured on March 30, 2014, by the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite. The composite image of the eastern hemisphere was compiled from eight orbits of the satellite and ten imaging channels, then stitched together to blend the edges of each satellite pass.
