7.3.2 Variable Description/Definition

The descriptions of the parameters contained in the data files on
the CD-ROM are:

         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.
SPECIES                        Botanical (Latin) name of the species (Genus 
                               species).
SAMPLE_MONTH                   The month during which the data were measured.
NEEDLE_AGE                     Age of the sampled needles,(0 = current year, 1
                               = 1 year old, 2 = 2 years old, etc.).
SAMPLE_AMOUNT                  The number of trees sampled.
MEAN_STARCH_CONTENT            The mean starch content of the sample.
STD_ERR_STARCH_CONTENT         Standard error for the starch content of the 
                               sample.
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.
