The Atmospheric Tomography (ATom) Mission is an Earth Venture Suborbital-2 mission to measure greenhouse gases and human-produced air pollution in remote areas.

Body

Five new datasets from ATom provide measurements of greenhouse gases and human-produced air pollution from 2016 to 2018.

Mean daily soil CO2 flux in each month of the non-growing season (NGS) during the baseline period (2003-2018). Gridded estimates are provided at 25-km resolution for the pan-Arctic and Boreal permafrost region.

Body

New data from the Arctic-Boreal Vulnerability Experiment (ABoVE) provide winter soil CO2 flux estimates for the pan-Arctic and Boreal regions.

Maps of the number of years since the most recent disturbance, aboveground biomass, and net ecosystem productivity in the year 2010, for forests of the Southeastern USA.

Body

A new Carbon Monitoring System dataset used a carbon cycle process model and historic data to estimate aboveground woody biomass and net ecosystem productivity over time.

Caption

Predicted spatially contiguous solar-induced chlorophyll fluorescence (SIF) across the United States for August 1 - 16, 2015. Areas of high SIF are in red, and areas of low SIF are in blue. Agricultural areas, like the U.S. Midwestern corn belt, often have a high rate of photosynthetic production which results in high SIF.

Body

High-resolution, global, estimates of SIF based on data from the OCO-2 satellite serve as a proxy for rates of terrestrial photosynthesis.
