SAR Data Help Keep Alaskans Safe           As winter ice in Alaska breaks up, areas of open water can be difficult to see—but not to synthetic aperture radar (SAR). Fresh Eyes on Ice, a NASA-funded project, uses SAR data and citizen scientists to assess ice cover and increase community awareness of hazardous conditions.                   The upcoming NASA/ISRO (Indian Space Research Organization) SAR (NISAR) mission will generate more data than any previous NASA Earth observation mission.

Protecting Workers in Remote Areas with NASA Active Fire Data Indji Systems, an Australian company, uses data from NASA’s Fire Information for Resource Management System (FIRMS) to help global customers in remote areas stay aware of natural hazards.           Monitoring Global Water Cycle Changes from Space The coastal ocean is extremely rich in providing signals of change for the global water cycle. A new Data in Action article describes how remotely sensed sea surface salinity observations are used to detect variations in the large-scale cycling of water.           The Data Behind a “Lost Winter” in the U.S. Midwest This past winter in the U.S. Midwest did not look much like winter due to significantly reduced snowfall. A Data in Action article shows how temperatures well above normal contributed to reduced snow and thin or absent ice on normally frozen ponds and lakes.           New Search Interface for Environmental Justice Data The NASA Environmental Justice Data Search Interface enables rapid search and discovery of Earth science data that can be used to understand and mitigate global environmental and climate-related injustices.           NASA Earth Science at the White House Dr. Manil Maskey, NASA Interagency Implementation and Advanced Concepts Team (IMPACT) deputy manager, participated as a panelist during the Networking and Information Technology Research and Development (NITRD) subcommittee’s artificial intelligence (AI) meeting at the White House on April 10.           A World of Data Visualizations Global winners in the Pale Blue Dot: Data Visualization Challenge used open Earth observation data to create visualizations to track microplastics, assess solar panel suitability, evaluate wildfire impacts, map disaster-driven food insecurity risks, and support groundwater well-drilling.

Preparing for PACE Data
Before the launch of NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite, the Python Top of Atmosphere Simulation Tool (PyTOAST) helped scientists prepare for working with data from PACE’s Ocean Color Instrument (OCI) and enabled them to test the data processing system code and instrument detection algorithms.

Tracking Tropical Storms with SmallSats           Getting tropical storm data rapidly helps manage these destructive events. Provisional data are now available from the Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of SmallSats (TROPICS) mission.                   Near-hourly observations of temperature, humidity, cloud ice and precipitation horizontal structure data from TROPICS are available through Earthdata Search.

Supporting the Best SWOT Science Careful calibration and validation ensure that the Ka-band Radar Interferometer (KaRIn) instrument aboard the Surface Water and Ocean Topography (SWOT) satellite collects the best science-quality data possible.           Keeping a Close Eye on Distant Volcanoes A NASA-funded online archive is making synthetic aperture radar (SAR) data easier to work with. Researchers used imagery from this archive in first-of-its-kind research measuring volcanic deformation in the remote Aleutian Islands.
