"Soil, Snow, Weather, and Sub-surface Storage Data from a Mountain Catchment in the Rain-
Snow Transition Zone", by P. Kormos, D. Marks, J. McNamara, C.J. Williams, H.P. Marshall, 
P. Aishlin and D. Chandler, Water Resources Research, 2013.

Spatial Data Projection Information:
	Universal Transverse Mercator (Zone 11)
	1983 North American Datum and Geodetic Reference System 1980 ellipsoid

Data presented in the paper include:
	MAIN DIRECTORY:
	12 time series files, comma delimited Ascii text with 1 header row
	2 soil texture files, comma delimited Ascii text with 1 header row
	1 snow density file, comma delimited Ascii text with 1 header row

	GIS DIRECTORY:
	34 rasters, tab delimited Ascii text with 6 header rows 
	3 shapefiles, including .dbf, .sbn, .sbx, .shx, .shp, .shp.xml, .prj files
	1 directory of images (.tif) of GIS files

The 12 time series files, 2 soil texture files, and 1 snow density file are located in the
MAIN directory and are described by README_DATA.txt located in that directory.

The 34 rasters include a bare earth digital elevation model, vegetation height data, and 
snow depth data.  The digital elevation model is DEM.txt. The vegetation height data files 
are VEG_HT_MAX.txt, VEG_HT_MEAN.txt, and VEG_HT_STDEV.txt.  The snow depth data include 
three rasters for each snow survey date. One with the average depth per pixel, one with the 
standard deviation of snow depths in each pixel, and one for the number of depth measurements 
in each pixel.  Snow raster files are DEPTHS_mmm_dd.txt, N_mmm_dd.txt, STD_mmm_dd.txt 
where mmm is the three letter abbreviation for the month and dd is the two digit day of month.
The 3 shapefiles are located in their own folders titled CATCHMENT_BOUNDARY, 
INSTRUMENT_LOCATIONS, and SOIL_MEAS_PTS and contain files named Catchment_Boundary.xxx, 
Instruments.xxx, and Soil_meas_pts.xxx, respectively. where the .xxx are the 7 different file 
extensions. The directory GIS_IMAGES contains tagged image format (.tif) pictures of each 
GIS file.

All data were collected within the Tree Line experimental catchment. The abbreviations used in 
the six-line headers of the raster ascii files are defined below.

ncols	          Number of Columns in Raster 
nrows	          Number of Rows in Raster
xllcorner      Easting Geographic Coordinate of Lower Left Pixel of Raster (m)
yllcorner      Northing Geographic Coordinate of Lower Left Pixel of Raster (m)
cellsize       Size of Pixels in Raster (m)
NODATA_value   The Raster Value for Instances of No Data
