High-Resolution Daily U.S. Surface Weather

Daily total precipitation and daily maximum temperature are animated over a
one-year subset (1997) of the 18-year Daymet U.S. Database of high-resolution
gridded daily surface weather parameters.Daymet U.S. Database

These animations show a one-year subset (1997) of the 18-year Daymet U.S.
Database of high-resolution gridded daily surface weather parameters. The
complete Daymet US Database, including references to methods, is available
on-line at http://daymet.ornl.gov/. The database is based on daily surface weather
observations from the National Weather Service Cooperative Station Network and
the Natural Resources Conservation Service SNOTEL network of upper-elevation
stations. These observations are interpolated to a grid with 1 km horizontal
spacing, and extrapolated to account for topographic effects on surface
weather. The complete database includes daily temperatures (max and min), daily
total precipitation, daily shortwave radiation, and daily average absolute
humidity, for the period 1980-1997. Numerous climatological summaries, both
annual and monthly, are available at the Daymet website. The website also
includes a map interface tool that allows a user to select a single point from
the 1 km grid, and receive all of the daily data for all variables for that
point. The subset of data shown in these animations helps to illustrate the
unique spatial and temporal characteristics of the Daymet US Database.
