Interpolated precipitation data (second interval) for 120 point locations within limestone cedar glades at Stones River National Battlefield near Murfreesboro, Tennessee

This dataset contains data collected within limestone cedar glades at Stones River National Battlefield (STRI) near Murfreesboro, Tennessee. This dataset represents interpolated estimates of precipitation (in decimal inches) for 120 quadrat locations (points) within 12 selected cedar glades, for a period of time from 3 days (72 hours) prior to the day of measurement up until the day of measurement. At each field visit, precipitation data was collected at four rain gauges installed at STRI. Rain gauge measurements were obtained on the following dates (which correspond to the fields in the dataset): February 6, 2012; March 5, 2012; April 2, 2012; April 23, 2012; May 25, 2012; June 21, 2012; July 19, 2012; August 23, 2012; September 27, 2012; November 5, 2012; December 17, 2012; January 21, 2013; February 18, 2013; March 19, 2013; April 15, 2013; and May 13, 2013. Points were classified into four groups (identified by the field "Group") and were visited on a rotating sampling schedule, such that each group of points was visited roughly once every four months. ArcGIS version 10 software (Esri, Redlands, CA, USA) was used to interpolate a raster surface between these rain gauges so that estimated precipitation values could be assigned to the 120 points used for hydrologic monitoring. First, a raster file was created based on an Inverse Distance Weighted (IDW) algorithm using rain gauge data as inputs, the default output cell size, and the default power of 2. Then, cell values from the interpolated raster were extracted to the 120 hydrologic monitoring points. Missing values (points not measured on a given day) are indicated by the value -99999.Detailed descriptions of experimental design, field data collection procedures, laboratory procedures, and data analysis are presented in Cartwright (2014).References:Cartwright, J.
