Southwest Purdue Agricultural Center Weather Data
The cooperative weather station at Vincennes has been in operation since 1887 with a few interruptions in the records before the turn of the 20th century. The first observer was W.P. Ritterskamp, who recorded the Wabash River gage heights and precipitation from a standard 8 inch rain gage.
There have been 12 observers at the weather station since 1887. The current station is located at the Southwest Purdue Agricultural Center just northeast of the city. The station was moved there in 1982 and is under the direction of Dennis Nowaskie, Superintendent. The longest tenure of any observer prior to SWPAC was Anthony B. Brouillette between 1920 and 1946.
Each day, maximum/minimum soil and air temperatures, and precipitation are recorded by Nowaskie or his associates. Humidity and evaporation were recorded until the late 1990's. This information is sent to the National Weather Service. The weather information is also published in the monthly "Climatological Data for Indiana".
Currently, there are five weather stations in use at the Southwest Purdue Ag Center.
National Weather Service (NWS): The manual collection of daily weather observations from this site are sent to the NWS via a web based application known as WxCoder. Data collected from this site can be viewed in the files below.
National Atmospheric Deposition Program (NAPD): The rain water collected from this site is used to characterize geographic patterns and temporal trends in wet chemical (primarily nitrogen and sulfur) atmospheric deposition and support assessments of atmospherically-deposited nutrients (nitrogen and sulfur) influencing crop productivity. Data collected from this site can be viewed at http://nadp.sws.uicu.edu/sites/siteinfo.asp?net=NTN&id=IN22.
National Mercury Deposition Network: The collection of rain water from this site is made in order to characterize geographic patterns and temporal trends in wet chemical mercury deposition and support assessments of atmospherically-deposited mercury on the productivity of biological accumulators such as fish.
AMEC - Clean Air Status & Trends Network (CASTNET): The weather data collected from this site is used to characterize geographic patterns and temporal trends in chemical atmospheric dry depositon, support assessments of atmospherically-deposited nutrients (nitrogen and sulfur) influencing crop productivity and evaluating source/receptor relationships of air pollutants. Data collected from this site can be viewed at http://epa.gov/castnet/javaweb/site_pages/VIN140.html.
Purdue Automatic Weather Station (PAAWS): Automated collection of weather data from this site is sent to a computer at the Indiana State Climate Office which can be observed at www.iclimate.org.
