Unidata's THREDDS Data Server (TDS) is a web server that provides metadata and data access for scientific datasets, using a variety of remote data access protocols.
A bug has been fixed in the THREDDS Data Server (TDS) NetCDF Subsetting Service (NCSS) that may, in rare cases, have returned incorrect results.
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.
Trends in maximum annual NDVI for natural vegetation within the Greater Yellowstone Ecosystem (GYE) from 1989 to 2014 (Emmett et al. 2019).
Daymet and North American Carbon Program (NACP) data were used to study Normalized Difference Vegetation Index (NDVI) trends across the Greater Yellowstone Ecosystem.
