Wetland Delineation Precipitation Data Retrieval from a Gridded Database
Obtaining a long-term precipitation data time-series for wetland delineation efforts can be a difficult and time-consuming process. Locating the nearest precipitation monitoring station to the wetland often proves challenging. Once a nearby monitoring location is identified, retrieving the data, accounting for gaps in the record, and generating the summary statistics can provide further challenges.
By offering access to “synthetic” data, this application assists users in overcoming some the challenges inherent in assembling a precipitation data set. The synthetic data are made up of regularly-spaced grid nodes whose values were calculated using data interpolated from Minnesota’s outstanding, but spatially and temporally irregular, precipitation data base.

Note to previous users of this application:
An updated data set has been implemented for the years 1973 through 1990. You may find that data retrieved previously will
differ somewhat from retrievals done henceforth for a given location.
