MiRS NOAA-20/ATMS Temperature at 700mb, 16 January 2018 NOAA-20 OMPS NM First Light Image, 5 January 2018 NOAA-20 OMPS NP First Light Image, 5 January 2018 NOAA-20 CrIS First Light Image, 5 January 2018 NOAA-20 VIIRS TEB First Light Image, 5 January 2018 NOAA-20 VIIRS First Light Image, 13 December 2017 NOAA-20 ATMS First Light Image, 29 November 2017

MiRS N20/ATMS Temperature at 700mb
STAR MiRS EDR team

16-Jan-18 - The top image shown is a map of atmospheric temperature at 700 millibars, approximately 3000 meters (10,000 feet), over the globe on January 16, 2018. The bottom two images shown side by side are the 700 mb temperature over North America on both January 16 (left) and January 11 (right), 2018. The most notable feature on January 16 over North America is the contrast between the extremely warm temperatures in northwestern Canada with the extreme cold, associated with a sharp dip in the jet stream over the US Midwest. The difference in temperature between the two features is more than 30 degrees Celsius (54 degrees Fahrenheit). Surface temperature observations confirm this extreme contrast: in Calgary, Alberta, the afternoon high temperature was 45°F on January 16th, whereas just five days earlier the afternoon high was only -15°F. In Nashville, Tennessee the opposite fluctuation occurred: on January 11th the high was a mere 17°F but five days later had reached 69°F. This pattern reversal is indicated in the NOAA-20 imagery, which shows the warmth focused in the eastern US, and sharply colder arctic air moving south into west-central Canada.

5-Jan-18 - The Ozone Mapping Profiler Suite (OMPS) instrument on the NOAA-20 satellite acquired its first data on January 5, 2018.
This first-light image shows the radiance values for the cloud reflectivity channel on the OMPS Nadir Mapper. The highest radiances are associated with bright cloud tops. The cloud reflectivity channel is one of the five primary channels used to estimate total ozone concentration. The striping pattern is created from the slight differences in the angle of the satellite relative to the incoming energy from the sun.

5-Jan-18 - The Ozone Mapping Profiler Suite (OMPS) instrument on the NOAA-20 satellite acquired its first data on January 5, 2018.
This first-light image shows the radiance at 307.5nm from the OMPS Nadir Profiler. This measurement is one of the 12 primary channels used to estimate the ozone at various levels in the atmosphere - closer to and farther from Earth's surface. The OMPS Nadir Profiler only makes measurements directly under the satellite's path.

NOAA-20 CrIS First Light Image
STAR CrIS SDR team

5-Jan-18 - Forty-eight days after JPSS-1 (NOAA-20) was launched into Earth orbit, it sent back its first Cross-track Infrared Sounder (CrIS) science data.
This image shows the global brightness temperature distribution at day time in one of the CrIS water vapor channels at 1598.75 cm-1. This channel is sensitive to water vapor amount around 500 hPa, and to mid- to high-level clouds. Dark blue colors in the image represent liquid water and ice clouds. Yellows indicate that the radiation is from the warm Earth's surface, or a dry layer in the middle troposphere. The image captured the blizzard striking the northeast coast of the United State on January 5, 2018.

NOAA-20 VIIRS TEB First Light Image
-- Captured Detailed Thermal Imagery of Bomb Cyclone

5-Jan-18 - Forty-seven days after it was first launched, the NOAA-20 polar-orbiting satellite sent back its first thermal infrared images on January 4, 2018. This VIIRS thermal infrared image shows stunning detail of the powerful 'bomb cyclone' that struck the East Coast of North America on Jan. 2-3, 2018. The powerful winter nor'easter delivered snow and ice, 50 to 80 mph wind gusts, and strong surf from northern Florida to Nova Scotia, Canada. Due to its rapid intensification (the barometric pressure at the center of the storm dropped 59 millibars in 24 hours), the storm ranks among the strongest ever observed along the East Coast.

-- Captured Thomas Fire

13-Dec-17 - Twenty-five days after JPSS-1 (NOAA-20) was launched into Earth orbit, NOAA-20 sent back its first Visible Infrared Imaging Radiometer Suite (VIIRS) science data on December 13, 2017.
This VIIRS true color image captured the aggressive wildfires across the Southern California region which forced thousands to flee their homes. The fire spanned more than 370 square miles and remains the strongest blaze for firefighters to battle in Ventura and Santa Barbara counties.

NOAA-20 ATMS First Light Image
STAR ATMS SDR team

29-Nov-17 - Eleven days after JPSS-1 (NOAA-20) launched into Earth orbit, the satellite sent back its first Advanced Technology Microwave Sounder (ATMS) science data on November 29, 2017.
This image uses ATMS data to depict the location and abundance of water vapor (as associated with antenna temperatures) in the lower atmosphere, from the surface of the Earth to 5 kilometers altitude. Grey colors depict areas with less water vapor, blue-green and purple colors represent abundant water in all phases in low and middle latitudes. In the polar regions, purple depicts surface snow and ice.

Message from the Program Manager: In November JPSS-1, now NOAA-20 launched from Vandenberg Air Force Base. Data from ATMS began flowing late in the month and the ATMS SDR team, as well as the MiRS team, which uses ATMS to produce EDR products did initial testing and found the data to be good. The report can be found here
