Publication_Date: 200504 Title: NAWQA GIS ancillary data: Mean annual precipitation and temperature (1980-97 DAYMET data) for ground water study areas (Land Use Studies and Subunit Surveys) Online_Linkage: Description: Abstract: This data set consists of 1980-97 mean annual precipitation and temperature for NAWQA ground water study areas (Land Use Studies and Subunit Surveys). The precipitation and temperature data are from DAYMET. The precipitation and temperature input grids were prepared by James Falcone. Purpose: This is one of the ancillary GIS data layers developed to characterize NAWQA ground water studies for national synthesis of water-quality data. Supplemental_Information: The input data set did not include Alaska and Hawaii. Time_Period_of_Content: Time_Period_Information: Multiple_Dates/Times: Single_Date/Time: Calendar_Date: 1991 Single_Date/Time: Calendar_Date: 2001 Currentness_Reference: The data set is intended to represent conditions for the early 1990's to late 1990's. Status: Progress: Complete Maintenance_and_Update_Frequency: NAWQA cycle 2 study areas will be added as their boundaries become available. DAYMET will add years 1998-2001 to the period of record.

Process_Step: Process_Date: 20040331 Process_Description: Ground water study boundaries are gridded at 30 meters and snapped to the NLCDE. Data processing occurs at 30 meters resolution. The average precipitation and temperature were determined for the study area by running the GRID command, "zonalstats" with the mean option. Processing routines are from the NAWQA area characterization toolbox. Process_Step: Process_Date: 20040524 Process_Description: We realized that the source grids for precipitation and temperature were coded as "zero" instead of "no data" in areas outside the boundaries of the United States. This would have affected the mean calculated for LUS/SUS studies near the coastline or partly outside the United States. The means were recalculated using "no data" instead of zero.

Two kinds of ground water network polygon coverages exist: 1) BND coverages, which represent the entire areal extent of the hydrogeologic unit defined for study, and 2) TRG coverages, which delineate the targeted land use within the BND.
