A global map of predicted annual soil respiration (Rs) at 1 km spatial resolution created by applying the QRF model to gridded covariates. Right is a plot of the latitudinal mean predicted annual Rs.
A machine learning approach was used to derive the predicted annual soil respiration and uncertainty at a 1 km spatial resolution.

AirMOSS radar swaths flown in 2014 and 2015 in Alaska. In situ soil moisture and temperature profile measurements were obtained at the CALM (Circumpolar Active Layer Monitoring) and the UAF GIPL (Geophysical Institute Permafrost Laboratory, University of Alaska Fairbanks) sites and used to validate AirMOSS data products.
Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) radar data from Alaska are used to derive estimates of active layer thickness. Data from flights in 2014 and 2015 are now available.

Dr. Don McNeil and his students analyzing data in the classroom. The projected wall image on the left shows the result of a MODIS data subset using the ORNL DAAC’s Global Subsets Tool. The projected wall image on the right shows thematic maps of daily land surface temperature increase in North and South America and Antarctica using a laterally rotated Mollweide Earth projection.
