March 14, 2014: The ACIS priority scheme was adjusted to give the CF6 a higher priority than GHCN-Daily for the most recent 90 days.

September 3, 2013: GHCN-Daily was made the highest priority dataset in ACIS to reflect the order of precedence established by the National Climatic Data Center. This could result in some values changing since a previous generation of the same ACIS product. More information concerning this change is available on the ACIS Dataset Documentation web page.
