CANADA GLACIER HOLE STATION

1997/98 Metadata

Data files from the Hole, January 1998
 
calibrations
-------------
Calibration files from eddy correlation calibrations runs in camp (Lake Hoare), January 1998. Also includes calibration info for Koni's licor pyranometers run in the hole (along with the thermocouples) and for the 107 probes I left frozen into the ice.
 
programs
--------
This file contains campbell scientific datalogger programs for running the hole met equipment, for calling the stations using GraphTerm (.stn), and < other things (I have no idea what .fsl and .pdf files are).
Note: 10 minute sampling, GMT unless otherwise noted
To go from GMT to local add 13 hours - ie. 215 GMT = 1515 local

tc.dat -- data from thermocouple array mounted up cliff face. Includes LICORs.
ID=105,JD,time,Tair,RHair,Tc-low,Tc-med,Tc-high,Sin,Sout
JD 16 2320 -- 29 310
Note: Sin and Sout mounted facing into and away from cliff. Data recorded as milivolts. Conversion to W/m2 done in ~kjl/programs/caa978/clean.pro. Calibration constants in ~kjl/programs/caa978/licor.cal.
Note: early Tc data had wrong ref. temp, therefore only gives relative temps.
