  • January 25, 2018: A new tool has been developed to compare the data in the ACIS database to that in GHCN-Daily. This allows users to do things like see the quality flags attached to values in GHCN-Daily that (due to failed quality control) display as missing in ACIS. The tool is available at http://acis-compare.rcc-acis.org. In most cases, this tool will be more useful than the Dataset Comparison Tool found under "Other Products".
  • January 10, 2018: Annual normals have been added to the Daily/Monthly Normals product.
