The NOAA Monthly U.S. Climate Gridded Dataset (NClimGrid) consists of four climate variables derived from the GHCN-D dataset: maximum temperature, minimum temperature, average temperature and precipitation. Each file provides monthly values in a 5x5 lat/lon grid for the Continental United States. Data is available from 1895 to the present. On an annual basis, approximately one year of "final" nClimGrid will be submitted to replace the initially supplied "preliminary" data for the same time period. Users should be sure to ascertain which level of data is required for their research.

This dataset is a continuous parameter grid (CPG) of normal (average) annual precipitation data for the years 1981 through 2010 in the Pacific Northwest. Source precipitation data was produced by the PRISM Climate Group at Oregon State University.

The Canadian Metrology Center (CMC) gridded datasets containing wind, temperature, specific humidity and other flux's and ground level variables for the period from Jan 2006 until the current day. The CMC gridded dataset consists of 12 hourly (00, 12 UTC) Atmospheric variables at 28 levels with a resolution of 1 deg. Data has been stored with the following folder convention [cmcYYMM (YY=year, MM=month)], approximately 730 files totaling 28.10 GB per year, with each 12 hr file being 38.5 MB. This archive is updated on a daily basis.

These datasets are continuous parameter grids (CPG) of total annual precipitation data for the years 2000 through 2016 in the Pacific Northwest. Source precipitation data was produced by the PRISM Climate Group at Oregon State University.

These daily gridded observations at 1/8 degree spatial resolution (about 12 km) are a baseline dataset to be compered to downscaled climate predictions. The grid used is the same as has been used by other 1/8th degree spatial resolution downscaling projects. The updated data were processed exactly as in the reference above with the single exception of the precipitation time-of-observation adjustment. For this updated dataset, if a meteorological station has a time of observation before noon, the precipitation is assigned to the prior day, otherwise no adjustment is made.
