The Editor's Corner

Steve Platnick, EOS Senior Project Scientist

This summer—just ahead of the peak of the Atlantic Hurricane season—the NASA Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission released its “first light” images. TROPICS is a constellation of observing platforms that measures temperature, humidity, and precipitation with spatial resolution comparable to current operational passive microwave sounders—but with unprecedented temporal resolution. TROPICS is comprised of four 3U CubeSats,1 each hosting a 12-channel passive microwave radiometer. While the primary mission objective of TROPICS is to relate temperature, humidity, and precipitation structure to the evolution of tropical cyclone intensity, a diversity of other applications have also been identified for TROPICS, including data assimilation, rainfall monitoring, and disaster response. There are also plans for synergistic applications with other satellite missions—in particular with NASA’s other hurricane-focused CubeSat constellation: the Cyclone Global Navigation Satelllite System (CYGNSS). To learn more about these collaborations, see the 2023 Joint Applications Workshop on NASA's TROPICS and CYGNSS Satellite Missions. Links to many of the presentations are included on the agenda.

Also in this issue are summaries of NASA's 2023 Earth Day celebration at Union Station in Washington, DC, and the 2023 MODIS/VIIRS Science Team Meeting, as well as news and upcoming meeting/event highlights from NASA Earth Science.
