Daily Surface Weather Data for North America, pre-derived Climatologic Summaries, and spatially referenced cross-validation files with companion documentation files.
A THREDDS data server allows users to download data from a catalog within a Web browser or compatible client software.
Single Pixel Extraction Tool
Enter a single geographic point by latitude and longitude in decimal degrees. Daily data from the nearest 1 km x 1 km Daymet grid cell are extracted from the database and formatted as a table.
Data are available in a browser, for download, and plotted within a graphical visualization. Automate downloads using Web Services.
Retrieve data subsets for any pixel location, time period, variable and area subset programmatically using a RESTful Web Service.
Understanding these services allows a user to query and automate machine-to-machine downloads of data. Web Service client and libraries are available in multiple programming languages, allowing integration of subsets into users' workflow.
Tile Selection Tool
Daymet data distributed as gridded daily data in 2 degree x 2 degree tile subsets.
Subsets are referenced by TileID, assigned within the Daymet algorithm. TileID is consistent throughout all years of Daymet data. The daily gridded tile data contains a tarred file of individual netCDF files for each Daymet variable.
Climatologies Through SDAT
Climatologies available through the ORNL DAAC Spatial Data Access Tool (SDAT) provides access to geospatial data through Open Geospatial Consortium (OGC) standards-based Web Services.
Services allow users to select the spatial extent, format, projection and resolution of the data to be previewed and/or downloaded.
Fixed Sites Subsets
Daymet data are available through the MODIS/VIIRS Fixed Sites Subset Tool.
The tool provides customized subsets and visualizations of several MODIS/VIIRS land products and Daymet daily surface weather data for selected field and flux tower sites around the world. Spatial subsets are available for predefined areas of about 8 X 8-km centered on the selected sites.
