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. -------------------------------------------------------------------------------- 7.4 Sample Data Record SITE_NAME,SUB_SITE,DATE_OBS,TIME_OBS,SENSIBLE_HEAT_FLUX_BELOW_CNPY, LIC_LATENT_HEAT_FLUX_4M,KRYPTON_LATENT_HEAT_FLUX_4M,NET_RAD_10CM, SOIL_HEAT_FLUX_3CM_1,SOIL_HEAT_FLUX_3CM_2,SOIL_HEAT_FLUX_3CM_3, SOIL_HEAT_FLUX_3CM_4,SOIL_HEAT_FLUX_3CM_5,SOIL_HEAT_FLUX_3CM_6, SOIL_HEAT_FLUX_3CM_7,SOIL_HEAT_FLUX_3CM_8,SOIL_HEAT_FLUX_3CM_9, MEAN_SOIL_HEAT_FLUX_3CM,SOIL_HEAT_FLUX_8CM,SOIL_HEAT_STORAGE_RATE, SURFACE_SOIL_HEAT_FLUX,CO2_FLUX_BELOW_CNPY,MEAN_CO2_CONC_4M, SDEV_CO2_CONC_4M,BOWEN_RATIO_4M,KINEM_MOMENT_FLUX_4M,DOWN_PPFD_10CM, WIND_DIR_4M,WIND_SPEED_4M,FRICTION_VEL_4M, WIND_SPEED_RESULTANT_VECTOR_4M,WIND_DIR_RESULTANT_4M, MEAN_U_WIND_SPEED_4M,MEAN_W_WIND_SPEED_4M,VAR_W_WIND_SPEED_4M, SDEV_W_WIND_SPEED_4M,ABS_HUM_4M,MEAN_LIC_ABS_HUM_4M, SDEV_LIC_ABS_HUM_4M,MEAN_KRYPTON_ABS_HUM_4M, SDEV_KRYPTON_ABS_HUM_4M,MEAN_AIR_TEMP_4M,SDEV_AIR_TEMP_4M, SOLENT_AIR_TEMP_4M,SOIL_TEMP_2CM,SOIL_TEMP_5CM,SOIL_TEMP_10CM, SOIL_TEMP_20CM,SOIL_TEMP_50CM,SOIL_TEMP_100CM, MEAN_SOIL_TEMP_INT_3CM,SOIL_WATER_POTENT_3CM, SOIL_WATER_POTENT_6CM,SOIL_WATER_POTENT_46CM, GRAV_SOIL_WATER_CONTENT_3CM,REL_HUM_4M,BOLE_TEMP_2MM, BOLE_TEMP_4CM,BOLE_TEMP_8CM,BOLE_TEMP_12CM,BOLE_TEMP_158MM, HAZEL_BOLE_TEMP_2MM,SNOW_IRT_TEMP,SNOW_TEMP_6CM,SNOW_TEMP_12CM, SNOW_TEMP_18CM,SNOW_TEMP_24CM,SNOW_TEMP_30CM,SNOW_TEMP_36CM, SURF_PRESS,DATA_QUALITY_FLAG,COMMENTS,CRTFCN_CODE,REVISION_DATE 'SSA-9OA-FLXTR','9TF01-UNS01',12-OCT-1993,2,.436,27.04,6.675,,,,, ,,,,,,,,,,2.9773,348.5,6.856,,-.002,,,.384,,,,,,,.066,,4.141,1.269, 2.524,.454,1.547,.032,,,,,,,,,,,,,,,,,,,,,,,,,,,94.72,'0', 'P S00:02:17','CPI',18-AUG-1999 'SSA-9OA-FLXTR','9TF01-UNS01',12-OCT-1993,30,.292,.149,3.499,,,,, ,,,,,,,,,,.4636,355.7,.709,,-.003,,,.343,,,,,,,.064,,5.47,.008, 3.133,.21,1.506,.021,,,,,,,,,,,,,,,,,,,,,,,,,,,94.71,'0','P', 'CPI',18-AUG-1999
