Plant heat and carbon dioxide measured together (ECOSTRESS + OCO-3)

ECOSTRESS/OCO-3 Co-Located Observations
atmosphere NASA GES_DISC Level 3
In plain English

What it measures. Side-by-side measurements over the same patches of land of plant water and heat (surface temperature, evapotranspiration, water-use efficiency) together with plant photosynthesis signals and carbon dioxide in the air.

How it's made. Built by matching observations in space and time from two instruments on the International Space Station, ECOSTRESS and OCO-3, then averaging them onto a shared roughly 557 m grid.

How & where you'd use it. Gives researchers a ready-made, paired view of vegetation and the atmosphere together, useful for studying how plants use water and carbon and for modeling ecosystems.

Official description

The ECOSTRESS/OCO-3 (“ECOCO3”) data set consists of spatially and temporally co-located observations from the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) and the Orbiting Carbon Observatory 3 (OCO-3) instruments currently operating on the International Space Station. Land Surface Temperature, Evapotranspiration, and Water Use Efficiency data products from ECOSTRESS, and Solar-Induced Chlorophyll Fluorescence and Dry-Air Column Mole Fraction CO2 from OCO-3 are matched in space and time over 3°x3° areas across the globe where OCO-3 performs Snapshot Area Map and Target mode observations. The original, native resolution data products are filtered for data quality and spatially averaged onto a 0.005°x0.005° uniform grid, i.e., 557m x 557m or 0.3km2 at the Equator. The aim of the ECOCO3 product is to provide users with synergistic, high-quality data of terrestrial vegetation and atmospheric parameters, for easy and ready use in scientific analysis and modeling. 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 through January 2023, from the start of OCO-3 observations through the end of ECOSTRESS Collection 1.
