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.

Daymet data were used to investigate how bird species respond to extreme weather conditions throughout eastern North America.

Registration is now open for the first NASA Plankton, Aerosol, Cloud, ocean Ecosystem Mission (PACE) Applications Virtual Workshop.
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.
The Single Pixel Extraction Tool allows a user to obtain daily Daymet data in a tabular format for a single geographic point (pixel) specified by latitude and longitude.
Daymet gridded estimates of daily weather parameters are now available for the years 1980 to 2019.
30-year annual average maximum temperature for Alaska at 60-m resolution for (a) the last glacial maximum period ~18,000 years ago and (b) the modern period 1975-2005.
A new dataset provides 30-year climate 'normals' for the last glacial maximum (~18,000 years ago) and the present day in Alaska.

Dr. Don McNeil and students at Prince of Songkla University in Thailand use NASA Earth observing data to study environmental change.
The NOAA Single Particle Soot Photometer (SP2) is a laser-induced incandescence instrument primarily used for measuring the black carbon mass content of individual particles.
Black carbon concentrations were measured over remote regions of the Earth during NASA's Atmospheric Tomography (ATom) Mission.
