A limited update to the 1991-2020 PRISM monthly and annual normals (M5) for tmax, tmin, tmean, tdmean, vpdmax, and vpdmin has been made (ppt monthly normals remain at version M4). Changes made to the previous 1991-2020 normals (M4) released in November 2021 involve adjustments to a limited number of grid cells along the US West Coast to align with the recently developed daily normals. The updated normals are available in the Normals section, and are also available via FTP and web services. Specific dataset information is available in our updated datasets document.
