Time-series of ground-based column-averaged dry air mole fractions of CO2 (xco2), CH4 (xch4), and CO (xco).

Average maximum temperature for a 24-hour period over an annual period.

Spatial distribution of eight wolf study populations used in an assessment (from 2000-2017) of denning phenology in response to climate signals. The base map shows the day of the year representing the NDVI-derived start of the growing season in 2010. 

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.

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.

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.

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.
