7.3.2 Variable Description/Definition


HYD03_SWE_DATA

         Column Name                             Description
------------------------------ ------------------------------------------------
SITE_NAME                      The identifier assigned to the site by BOREAS,
                               in the format SSS-TTT-CCCCC, where SSS identifies
                               the portion of the study area: NSA, SSA, REG,
                               TRN, and TTT identifies the cover type for the
                               site, 999 if unknown, and CCCCC is the identifier
                               for site, exactly what it means will vary with
                               site type.
SUB_SITE                       The identifier assigned to the sub-site by
                               BOREAS, in the format GGGGG-IIIII, where GGGGG is
                               the group associated with the sub-site 
                               instrument, e.g. HYD06 or STAFF, and IIIII is the 
                               identifier for sub-site, often this will refer to 
                               an instrument.
DATE_OBS                       The date on which the data were collected.
MEAN_SNOW_DEPTH                The average depth of snow.
SWE_NUM_OBS                    Number of snow water equivalent (SWE)
                               measurements taken.
MEAN_SNOW_DENSITY              The mean snow pack density.
CALC_SWE                       Calculated snow water equivalent.
CAN_SNOW_SAMPLER_SWE           This is the snow water equivalent that was measu
                               red from the Canadian snow sampler.
CAN_SNOW_SAMPLER_NUM_OBS       This is the number of measurements that were made
                               at the site with the Canadian snow sampler.
CRTFCN_CODE                    The BOREAS certification level of the data.
                               Examples are CPI (Checked by PI), CGR (Certified
                               by Group), PRE (Preliminary), and CPI-??? (CPI 
                               but questionable).
REVISION_DATE                  The most recent date when the information in the
                               referenced data base table record was revised.
