Mesonet at SDState's archive maps
The new experimental archive mapping tool dynamically creates a state wide view of the Mesonet's historical weather and climate related information. This tool makes it easy to see the daily values across the state at a glance and gain a better understanding of how each station location compared to it's neighbors over time.

This tool defaults to the most recent available day, but offers years worth of valuable data for those that need access to something older.
How to use this tool:
  • Clicking the date box in the top right corner of the map allows for easy change of which day's data is displayed. Use the pop-up calendar to find the day of choice.
  • The and buttons (left side) change the date to previous or next day. This allows for easy access to small date changes.
  • Use Select Layer dropdown (right side) to choose which data overlay is shown. See "Map Details" below the map for more details about each layer.
