Abstract: GPS locations of permanent climate and precipitation stations at Coweeta Hydrologic Laboratory.
Location(s), Described: GPS locations of permanent climate and precipitation stations at Coweeta Hydrologic Laboratory.
Location(s), Download GPS: ArcView Shape Files (shp.):  UTM, NAD83, Zone 17  |  Lat/Lon
Location(s), Online Maps: USGS Topographic-based Maps of Research Sites
(Printable for fieldwork)
Methods/Experimental Design: Use Trimble Pro-XRS 12-channel DGPS with differential correction and a filtered PDOP of less than 3 in 3D mode to fix the positions of each gradient plot and expanded gradient plot corner. This project will be completed by field  technicians as time permits between other sampling duties.
