Dr. Peter Thornton studies the interactions of land ecosystems with other components of the Earth's climate system including biogeochemical and physical land-atmosphere feedbacks, and interactions with human systems.
For the third consecutive year, Dr. Peter Thornton has been recognized for exceptional research.
Four variables for the same 3-hour timestep, December 8, 2015, 12:00 AM to 3:00 AM, a) precipitation flux (kg m-2 s-1) b) air temperature (K) c) shortwave radiation flux (W m-2) d) specific humidity. Source: western_USA_precipitation_3hr_2015-12.nc4
High-resolution climate data inputs are now available for 11 states in the western U.S.
Each black dot on this digital elevation map (DEM) represents a surface weather station in continental North America providing Daymet data in 2010. Additional stations providing Daymet data are located in Puerto Rico and Hawaii.
Daymet derived annual average of daily minimum temperature, 1980 (left) and 2019 (right), for a subset of North America. Images are scaled from -20 to +20 degrees C.
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.
