Atmospheric rivers are long, narrow conveyor belts of moisture that move through the atmosphere. Strong atmospheric rivers can deliver enormous amounts of rain and high-elevation snow in California, Pacific Northwest, and Alaska, especially during the winter months. The GOES-R Series Advanced Baseline Imager provides improved detection and monitoring of atmospheric river events. Understanding and anticipating the role of atmospheric rivers is important for water and emergency management on the West Coast, particularly in California. GOES-17, recently designated NOAA’s GOES West operational satellite, is positioned to keep an eye on the western U.S., Alaska and Pacific Ocean, and provide advanced monitoring of atmospheric rivers among other weather phenomena and hazards.
In 2018, the NOAA Search and Rescue Satellite Aided Tracking (SARSAT) system helped save 340 lives with the aid of NOAA satellites like GOES-16. In addition to carrying instruments for monitoring our atmosphere, land and oceans for severe weather and other hazards, GOES-16 also carries a SARSAT transponder to help locate people in distress. This transponder provides the capability to immediately detect distress signals from emergency beacons and relay them to ground stations. In turn, this signal is routed to a SARSAT mission control center and then sent to a rescue coordination center, which dispatches a search and rescue team to the location of the distress.
GOES-17 is now operational as NOAA’s GOES West. In its new role, GOES-17 is providing faster, more accurate, and more detailed observations for detecting and monitoring Pacific storm systems, fog, wildfires, and other weather phenomena that affect the western United States, Alaska, and Hawaii. Located at 137.2 degrees west longitude, GOES-17 replaces GOES-15 as NOAA’s operational GOES West. GOES-17 joins GOES-16, in operations as NOAA’s GOES East, in delivering high-resolution visible and infrared imagery and lightning observations of more than half the globe – from the west coast of Africa to New Zealand and from near the Arctic Circle to the Antarctic Circle.

GOES East captured a partial solar eclipse on February 5, 2019. In this animation from the satellite’s Solar Ultraviolet Imager (SUVI) instrument, you can see the moon passing across the sun. A partial eclipse occurs when the sun and moon are not exactly in line with the Earth and the moon only partially obscures the sun.
On February 1, 2019, at 1:17 p.m. EST, the GOES-16 Geostationary Lightning Mapper (GLM) detected a bright meteor over northwestern Cuba. The meteorite landed near Viñales, Pinar del Río in western Cuba. While designed for mapping lightning flashes, GLM can observe large meteors anywhere throughout its coverage area. The instrument takes 500 images of Earth every second, allowing it to measure the shape of a meteor “light curve,” or the change in brightness of a meteor with time, with millisecond precision.
The GOES-16 Advanced Baseline Imager also detected the airborne debris cloud as it drifted northeastward then eastward for about an hour after the impact. The signatures in the split cloud top phase and split window imagery were due to the presence of mineral dust particles within the debris cloud — the emissivity properties of dust affects the sensed brightness temperatures differently for various infrared spectral bands. The cirrus spectral band is useful for detecting the scattering of light by airborne particles such as ice crystals, volcanic ash, smoke or dust. The debris cloud was also casting a subtle shadow onto the surface, as seen in the visible imagery.
The GOES-R Series Program quarterly newsletter for the time period October – December 2018 is now available. GOES-17 completed its Handover Readiness Review and the program handed the satellite over to NOAA’s Office of Satellite and Product Operations. GOES-17 is now in its operational location at 137.2 west and is providing stunning imagery of the U.S. West Coast, Alaska, Hawaii, and even New Zealand. The satellite is ready for operations as NOAA’s GOES West.
This conference merges three satellite conferences into one major event. NOAA, the American Meteorological Society (AMS) Satellite Meteorology, Oceanography, and Climatology (SatMetOC), and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) will hold a joint conference September 29 – October 4, 2019, in Boston. Abstract submissions are due on March 1, 2019.
