With this application, you can total a parameter of your choice over a duration of your choice. The resulting data is presented graphically as well as textually for use in a GIS. The end date is inclusive to the data presented. The raw daily data used for this application can be downloaded from here.
*Note: Only a sub-sample of stations are plotted on the map due to
space restrictions. The small four digit label is the station identifier used
in the data listing below (without the 2 character state identifier included).
