Gridded Weather Data

gridMET surface meteorological dataset

The gridded surface meteorological dataset called gridMET covers the contiguous US at a 4-km spatial resolution from 1979-present. While these data can capture local variability in climate, they are unable to resolve microclimate variations that may be present at finer scales (e.g., within a farm). Data are updated daily currently with a ~14-hour latency such that data through approximately midnight are produced and uploaded to our data system by around 2PM.

HOW WERE THESE DATA CREATED?

These data blend the high quality spatial attributes of PRISM with the temporal attributes and additional data from NLDAS-2. ​For additional information visit the gridMET main page.

HOW CAN I ACCESS THESE DATA?

There are several ways to access the catalog of data. Depending on your exact interests we suggest the following:

  1. Access time series for selected locations or aggregated region (e.g., county-average) using Climate Engine: http://clim-engine.appspot.com/
  2. Download the full data over CONUS in netCDF format.
  3. ​Download a subset of the data using your favorite software program (i.e., MATLAB, Python, R, IDL) and an OPeNDAP connection to the data through NKN's THREDDS server. See our example on how this works.
