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.

Dr. Don McNeil and students at Prince of Songkla University in Thailand use NASA Earth observing data to study environmental change.
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.
New data from the Arctic-Boreal Vulnerability Experiment (ABoVE) provide winter soil CO2 flux estimates for the pan-Arctic and Boreal regions.
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.
High-resolution, global, estimates of SIF based on data from the OCO-2 satellite serve as a proxy for rates of terrestrial photosynthesis.
Spatial distribution of PhenoCam data across ecological regions of North America. Background map illustrates USA Environmental Protection Agency Level I Ecoregions. Data counts have been aggregated to a spatial resolution of 4i, and the size of each circle corresponds to the number of years of data.
A new version of the PhenoCam vegetation phenology data products is now available.
