Hello! You are receiving this email because you are on the prism-updates mailing list, which provides news about PRISM weather and climate data. Below is important information on PRISM data updates and alerts. === New version of the PRISM 1991-2020 normals === After months of work, a new version of the PRISM 1991-2020 normals has been released. Version M3 of the 1991-2020 PRISM monthly and annual 30-year normals was released in December 2021. Version M4, released in December 2022, incorporates a more stable method for adjusting short-period-of-record station averages, as well as additional data quality control measures. Please note that version M4 supersedes version M3. The updated 1991-2020 normals can be retrieved via FTP, web services, or the PRISM website (https://prism.oregonstate.edu/normals). Additional information can be found in the PRISM Datasets document (https://prism.oregonstate.edu/documents/PRISM_datasets.pdf). Best wishes, PRISM Climate Group
