PARM_VALUE FLAGS Description
----------------------------
The third to last column in the data set shows the parameter flags.  There is 
one flag for each parameter plus three extra as explained below.  This data set 
is based upon the 1994 to 1996 SRC Meteorological Data.  In order to make a 
continuous data set with no missing data gaps, it was necessary to substitute 
data from other data sets when the SRC data was missing.  The parameter flags 
show the source of each parameter.  For example, consider the data set from SSA-
OA.  All available data from the SRC tower at SSA-OA is first put into the data 
set.  This is considered original data and each parameter will show an original 
data source flag (O).  (See below for specific flag definitions).  If data is 
missing from a site for longer than what is allowed for linear interpolation 
(two hours), it was substituted from another site.  The first step is to 
substitute data from the other SRC site within the same study area.  In the case 
of the SSA, this would be SRC SSA-OJP.  The parameters will then have a 
substituted flag (S).  If data is missing from SRC SSA-OJP, the next step is to 
substitute data from the flux tower at SSA-OA.  The parameter will then have the 
TF SSA-OA substitution flag (A).  If data is not available from TF SSA-OA, the 
next step is to substitute data from the flux tower at SSA-OJP.  The parameter 
will then have the TF SSA-OJP substitution flag (J).  If data is not available 
from TF SSA-OJP, the final step is to use a method of estimating the data as 
explained in Section 9.3.

PARAMETER FLAGS FOR SSA-OA, SSA-OJP, NSA-OJP
There are a total of twenty-two one-letter flags in the flag column.  The first 
nineteen of these flags correspond to the nineteen parameters and show the 
source of each corresponding parameter.  The last three flags give additional 
information about certain parameters (see Section 9.1.1).  The first of these 
last three is the PRECIPITATION GAUGE FLAG.  The second is the PRECIPITATION 
ZEROED FLAG.  The last is the SNOW DEPTH ZEROED FLAG. 

PARAMETER FLAGS FOR NSA-YTH
There are seventeen parameter columns for the NSA-YTH data set since this site 
did not measure DIFFUSE INCOMING SHORTWAVE RADIATION and INCOMING LONGWAVE 
RADIATION.  There are a total of twenty one-letter flags in the flag column.  
The first seventeen of these flags correspond to the seventeen parameters and 
show the source of each corresponding parameter.  The last three flags give 
additional information about certain parameters (see Section 9.1.1).  The first 
of these last three is the PRECIPITATION GAUGE FLAG.  The second is the 
PRECIPITATION ZEROED FLAG.  The last is the SNOW DEPTH ZEROED FLAG. 

Following is a list of all flags.

PARAMETER FLAG DESCRIPTION:

A     This flag denotes the substitution of SSA-OA flux tower data that were 
linearly interpolated to 15 minutes from the existing 30 minute data.  The 
SSA-OA flux tower data are used for the SSA-OA site when SRC data are not 
available from SRC SSA-OA or SRC SSA-OJP.   The SSA-OA flux tower data are 
also used for the SSA-OJP site when data are not available from SRC SSA-
OJP or SRC SSA-OA or SSA-OJP flux tower.  Although the actual flux tower 
measurements were made at 0 and 30 minutes past the hour, the 'A' 
designation is used for data from the flux tower at 15 and 45 minutes past 
the hour which were linearly interpolated from the existing 30 minute 
data.

C     This flag denotes the substitution of linearly interpolated SSA-OA flux 
tower data when a gap of less than 2 hours existed in the SSA-OA flux 
tower data.

D     This flag denotes the estimation of DIFFUSE INCOMING SHORTWAVE RADIATION 
      that was estimated using the techniques described in section 9.3.1.

E     This flag denotes the substitution of derived DIFFUSE INCOMING
      SHORTWAVE RADIATION from the other site within the same study 
      area when the TOTAL INCOMING SHORTWAVE RADIATION value was substituted
      from the other site.  This was done so that both total and diffuse 
      shortwave values come from the same site for a more accurate 
      relationship.

H     This flag denotes the substitution of precipitation and snow 
      depth data from Thompson airport when data from both the NSA-OJP 
      and NSA-YTH sites were missing.

J     This flag denotes the substitution of SSA-OJP flux tower data that were 
linearly interpolated to 15 minutes from the existing 30 minute data.  The 
SSA-OJP flux tower data is used for the SSA-OJP site when SRC data is not 
available from SRC SSA-OJP or SRC SSA-OA.  The SSA-OJP flux tower data is 
also used for the SSA-OA site when data is not available from SRC SSA-OA 
or SRC SSA-OJP or SSA-OA flux tower.  Although the actual flux tower 
measurements were made at 0 and 30 minutes past the hour, the 'J' 
designation is used for data from the flux tower at 15 and 45 minutes past 
the hour which were linearly interpolated from the existing 30 minute 
data.

K     This flag denotes the substitution of linearly interpolated SSA-OJP flux 
tower data when a gap of less than 2 hours existed in the SSA-OJP flux 
tower data.

L     This flag denotes data that were linearly interpolated from original SRC
      data when data were missing for less than two hours.

M     This flag is used in the soil temperature flag columns when the
      time-step method of linear interpolation is used (see Section 
      9.3.1.).  Data were missing for more than two hours from both SRC sites 
      but could not be substituted from a flux tower as these data 
      were not measured at flux towers.  Therefore, data from a specific time 
      of day on the last day of known values were used with data from the same 
      time on the first day of known values after the missing block to
      interpolate values at that time on all the missing days. 

O     This flag denotes original SRC data.

R     This flag denotes the estimation of REFLECTED SHORTWAVE RADIATION using 
      the techniques described in section 9.3.1.

S     This flag denotes the substitution of this parameter from the other SRC 
      tower within the same study area.  This was done when data were missing 
      for more than two hours (otherwise it would be linearly interpolated).
      When data were missing from SRC SSA-OA tower, data from SRC SSA-OJP tower 
      were used and vice versa.  When data were missing from SRC NSA-OJP tower, 
      data from SRC NSA-YTH tower were used and vice versa.

W     This flag denotes the estimation of INCOMING LONGWAVE RADIATION using 
      the techniques described in section 9.3.1.

?     This flag denotes pressure data that is incorrect and should only be 
      used to obtain pressure trends.  (see Sections 10.1 and 11.2.)

PRECIPITATION GAUGE FLAGS:

B     This flag denotes the use of a Belfort weighing precipitation gauge 
      (winter only) for the water-equivalent precipitation data.

T     This flag denotes the use of a tipping bucket rain gauge (not available in
      winter) for the liquid-only precipitation data.


PRECIPITATION ZEROED FLAGS:

O     This flag denotes the use of original precipitation data.

Z     This flag is used when, because of sensor error, the measured
      value was negative and has been set to zero.  If this data has been 
      substituted from another site, this flag is left as O but the parameter
      flag shows the substitution flag.  (see Section 9.3.1.)

SNOW DEPTH ZEROED FLAGS:

O     This flag denotes the use of original snow depth data.

Z     This flag is used when, because of sensor error, the measured
      value was negative and has been set to zero.  If this data has been 
      substituted from another site, this flag is left as O but the parameter 
      flag shows the substitution flag.  (see Section 9.3.1.)

--------------------------------------------------------------------------------
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.
