Rapid changes in terrestrial carbon dioxide uptake captured in near-real time from a geostationary satellite: The ALIVE framework

The terrestrial carbon cycle responds dynamically to human activity, weather and climate variability, and extreme events. Satellite remote sensing has revolutionized our ability to estimate ecosystem carbon uptake via gross primary productivity (GPP) with increasing accuracy and spatial resolution. Many aspects of terrestrial carbon cycling happen quickly, and may not be captured at the temporal scales of most remote sensing products – often multiple days or longer. Imagers onboard geostationary satellites measure the Earth system at “hypertemporal” time scales of minutes or less, and often have the spectral capabilities to estimate GPP and other surface-atmosphere fluxes at this rapid cadence. Here, we build upon established approaches for estimating GPP using the Advanced Baseline Imager (ABI) on the Geostationary Environmental Operational Satellite – R Series (GOES-R) to create ALIVEG…
