PACE in EGIS

NASA is now offering 11 new Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) data products – including imagery services to study ocean, land, and atmosphere with global, 8-day image composites at varied spatial resolutions (from 2 to 11 km) – geared for geographic information system (GIS) users. The products include ocean chlorophyll-a concentration (chl-a) and the terrestrial normalized difference vegetation index (NDVI) data as well as new, advanced products only from PACE. Read descriptions of each of these imagery services and visually explore all imagery services together as map layers. 

PACE imagery services are useful for applications in water resources, land monitoring and management, and air quality. For example, aquatic products help users identify and track regional phytoplankton blooms and monitor changes in water optical properties continuously over weeks to months. 

With the PACE land vegetation indices, it is possible to track monthly and seasonal changes in vegetation growth and photophysiology, which are metrics related to plant primary productivity and health. Air quality indicators, such as aerosol optical depth (AOD) and nitrogen dioxide concentration, provide first-order metrics of regional-scale air quality.
