U.S. Monthly Gridded Precipitation and Temperature Climate Normals for 2006-2020 (NCEI Accession 0248761)

A 1/24 degree by 1/24 degree (~5 km) gridded data set consisting of monthly precipitation and temperature values for the conterminous U.S. was published as part of generating new division climate normals. The underlying data set is nClimGrid, and this is based on a set of station anomalies observed in any given month interpolated spatially using climate guidance and reconstructed into whole values. The resulting monthly grids are the equivalent of homogenous temperature and serially complete precipitation records. Therefore, a simple 15-year average of monthly grids from 2006-2020 yields directly a set of gridded climate normals. Monthly gridded climate normals are calculated for total precipitation, and maximum, minimum and average temperature.
