NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC) has released ECOCO3 version 1.0, making more than 3.5 years of spatially and temporally correlated ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) and Orbiting Carbon Observatory-3 (OCO-3) observations available. These data provide users with synergistic, high-quality data of terrestrial vegetation and atmospheric parameters for easy and ready use in scientific analysis and modeling. Both ECOSTRESS and OCO-3 are currently operating on the International Space Station (ISS), providing observations which are filtered for data quality and spatially averaged onto a 0.005° x 0.005° uniform grid, i.e., 557m x 557m or 0.3 km2 at the Equator.
Land surface temperature, evapotranspiration, and water use efficiency data products from ECOSTRESS and solar-induced chlorophyll fluorescence and dry-air column mole fraction CO2 data products from OCO-3 are matched in space and time over 3° x 3° areas across the globe where OCO-3 performs 'Snapshot Area Map' and 'Target' mode observations. The initial V1.0 release is based on ECOSTRESS Collection 1 and OCO-3 Version 11 data products, for the common measurement period of August 2019 – January 2023, from the start of OCO-3 observations through the end of ECOSTRESS Collection 1.
