    • Biospheric CO2 surface flux estimates from the Vegetation Photosynthesis & Respiration Model (VPRM) in the eastern USA and Canada: November 2016 to December 2021

    Metadata Updated: September 30, 2025

    Monthly zip files from November 2016 to December 2021, with each zip containing hourly .tif files with gridded CO2 fluxes at 0.02 degree resolution in an eastern North American domain from 33° to 47° north and 92° to 67° west. Annual zip files from November 2016 to December 2021, with each zip containing hourly .tif files with gridded CO2 fluxes at 0.01 degree resolution in an eastern North American domain from 38.4° to 39.6° north and 77.8° to 76.2° west. For each hour, there is a file with ecosystem respiration fluxes, as well as a file for gross ecosystem exchange (GEE) during daytime hours only. To derive net ecosystem exchange, respiration and GEE fluxes must be summed. Units are micromoles per m2*s after dividing original data by 1000. Data updated as of 8/2/2024.
