Publication_Date: 20040816 Title: NAWQA GIS ancillary data: Mean annual precipitation and temperature (1980-97 DAYMET data) for sampling points Online_Linkage: Description: Abstract: This data set consists of 1980-97 mean annual precipitation and temperature for NAWQA sampling sites. The precipitation and temperature data are from DAYMET. The precipitation and temperature input grids were prepared by James Falcone. The sampling sites are from the NAWQA data warehouse. Purpose: This is one of the ancillary GIS data layers developed to characterize NAWQA sampling sites 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 sampling sites are added as their locations become available. DAYMET will add years 1998-2001 to the period of record.

Process_Step: Process_Date: 20040315 Process_Description: Intersected sampling points with each climate attribute using GRIDSPOT with Nearest option. The station is assigned the value of the grid cell that the point falls in. (March 2004 version of NAWQAPT.) Process_Step: Process_Date: 20040521 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 points off the coastline or outside the United States. Values were assigned to the points using "no data" instead of zero. Values changed for: !
