Soil Respiration Maps for the ABoVE Domain, 2016-2017 : Arctic-Boreal Vulnerability Experiment (ABoVE)

This dataset provides gridded estimates of carbon dioxide (CO2) emissions from soil respiration occurring within permafrost-affected tundra and boreal ecosystems of Alaska and Northwest Canada at a 300-m spatial resolution for 2016-08-18 to 2018-09-12. The estimates include monthly average CO2 flux...

Description
Summary:This dataset provides gridded estimates of carbon dioxide (CO2) emissions from soil respiration occurring within permafrost-affected tundra and boreal ecosystems of Alaska and Northwest Canada at a 300-m spatial resolution for 2016-08-18 to 2018-09-12. The estimates include monthly average CO2 flux (gCO2-C m-2 d-1), daily average CO2 flux and error estimates by season (autumn, winter, spring, summer), estimates of annual offset of CO2 uptake (i.e., vegetation GPP), annual budgets of vegetation gross primary productivity (GPP; gCO2-C m-2 yr-1), and the fraction of open (non-vegetated) water within each 300-m grid cell. Belowground sources of respiration (i.e., root and microbial) are included. The gridded soil CO2 estimates were obtained using seasonal Random Forest models, information from remote sensing, and a new compilation of in-situ soil CO2 flux from Soil Respiration Stations and eddy covariance towers. The flux tower data are provided along with daily gap filled flux observations for each Soil Respiration station forced diffusion (FD) chamber record. The data cover the NASA ABoVE Domain. Files are in GeoTIFF and comma-separated values (CSV) formats.
