2013 Daymet Data Available

Submitted by ORNL DAAC Staff on

The ORNL DAAC is pleased to announce that 2013 Daymet data is now available. Data is available for the conterminous U.S. and Southern Canada as ground station density allows.

Daymet: Daily Surface Weather Data on a 1-km Grid for North America, Version 2. Data set prepared by P.E. Thornton, M.M. Thornton, B.W. Mayer, N. Wilhelmi, Y. Wei, R. Devarakonda, and R.B. Cook.

This data set provides Daymet output data as mosaicked gridded estimates of daily weather parameters for North America, including continuous surfaces of day length, precipitation, shortwave radiation, snow water equivalent, maximum air temperature, minimum air temperature, and water vapor pressure. The Daymet data product was derived from selected meteorological station data by interpolation and extrapolation algorithms.

The current data product covers the period January 1, 1980 to December 31, 2013.

Other tools are provided on the ORNL DAAC Daymet website that allow extraction of Daymet variable daily data as a text file for a single pixel or the download of gridded Daymet data in 2 degree by 2 degree tile data sets.

The ORNL DAAC is one of twelve NASA funded Earth Observing System Data and Information System (EOSDIS) Distributed Active Archive Centers (DAACs) and is responsible for archiving and distributing terrestrial ecology and biogeochemical dynamics data.
