         Column Name                             Description
------------------------------ ------------------------------------------------
HYD06_SITE_ID                  The identifier assigned to the site by BOREAS,
                               in the format AAA-FFF-GGGGG-SMAC01 where AAA is
                               the study area, FFF is the flight line number,
                               GGGGG is the science group, and SMAC01 stands for
                               Soil Moisture Aircraft.

DATE_OBS                       The date on which the data were collected.
TIME_OBS                       The Greenwich Mean Time (GMT) when the data were
                               collected.

FLIGHT_LINE                    The designation for the line/transect over which
                               the aircraft flew.

HYD06_BIN                      The HYD-06 designation for the part of the
                               flight line over which the soil moisture
                               measurement was derived.

TOTAL_MOISTURE                 The percent moisture of mineral soil and moss
                               layer (if present) derived from gamma ray
                               emissions for the bin or flight line.

MEAN_WATER_CONTENT_MOSS_HUMUS  The average water content of the moss/humus
                               layer for the in-situ bin measurements.

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.

--------------------------------------------------------------------------------
Minimum Data Value -- The minimum value found in the column.
Maximum Data Value -- The maximum value found in the column.
Missng Data Value  -- The value that indicates missing data. This is used to
                      indicate that an attempt was made to determine the
                      parameter value, but the attempt was unsuccessful.
Unrel Data Value   -- The value that indicates unreliable data.  This is used
                      to indicate an attempt was made to determine the
                      parameter value, but the value was deemed to be
                      unreliable by the analysis personnel.
Below Detect Limit -- The value that indicates parameter values below the
                      instruments detection limits.  This is used to
                      indicate that an attempt was made to determine the
                      parameter value, but the analysis personnel determined
                      that the parameter value was below the detection
                      limit of the instrumentation.
Data Not Cllctd    -- This value indicates that no attempt was made to
                      determine the parameter value.  This usually
                      indicates that BORIS combined several similar but
                      not identical data sets into the same data base table
                      but this particular science team did not
                      measure that parameter.

Blank -- Indicates that blank spaces are used to denote that type of value.
N/A   -- Indicates that the value is not applicable to the respective column.
None  -- Indicates that no values of that sort were found in the column.
