User GuideResources
This dataset provides Daymet Version 3 annual summary climatologies at a 1-km x 1-km spatial resolution for four Daymet variables; minimum and maximum temperature, precipitation, and vapor pressure. Annual averages are provided for minimum and maximum temperature and vapor pressure, and annual totals are provided for the precipitation variable. These single year summary data products are produced for each individual year and cover the same period of record as the Daymet V3 daily data. The annual climatology summaries are derived from the much larger dataset of daily weather parameters (Thornton et al., 2016), produced on a 1-km x 1-km grid over North America including Canada, the United States, and Mexico. Separate annual summary files are provided for the land areas of Hawaii and Puerto Rico, which are also available as gridded daily files as part of the Daymet V3 dataset. Data are in a Lambert Conformal Conic projection for North America and are distributed in a netCDF file (version 1.6) format compliant to Climate and Forecast (CF) metadata conventions and geotiff file formats.
