Line Plots: Accumulated Daily Precipitation

By specifying a time period within the range of one to twelve months and clicking at a point on the map, you will generate a line plot of the accumulated precipitation averaged over the 1x1 degree latitude-longitude box containing that point. For comparison, the 5 year average (1996-2000) line is also plotted. The ending date will be the most recent date for which data is available, typically within 1-2 days of the current date.

Current daily precipitation data used in these plots is courtesy of the Climate Prediction Center (W. Higgins and W. Shi). These data are updated everyday at about noon (MST), with data through 12 UTC the previous day. Note: the climatology for this dataset is only a 5 year average, 1996-2000. Caution should be used in interpretting these plots in mountainous regions.
