DAYMET

Back to meteorological datasets

Field Value
Description Daymet offers daily surface meteorological data for North America, including variables such as temperature, precipitation, and radiation. Spanning from January 1980 to December 2022, it provides data at a 1 km spatial resolution. The dataset supports ecological, hydrological, and agricultural research.

Usage Policy Link
Usage Policy All Daymet data are publicly available, without restriction, according to the NASA Earth Observing System Data and Information System (EOSDIS) Data Use Policy. A NASA Earthdata Login account is generally required to download data. Users should cite the dataset (authors, version, DOI) when using the data. The data are distributed in CF-compliant netCDF format via web services (THREDDS, OPeNDAP), pre-packaged files, and web APIs (e.g. single-pixel access). The data are labelled as “provisional and subject to revision” (i.e. there may be future updates or corrections). For third-party or embedded content (e.g. images or materials not produced by Daymet/ORNL), additional permission may be needed where not covered by standard NASA / ORNL terms. The ORNL DAAC also supports standard web service and geospatial protocols (e.g. OGC WMS/WCS) for visualization and subset download.
