CANADA GLACIER MET/EC STATION


1994/95 Glacier Met/EC Metadata

 
This subdirectory contains met station data from
the 94-95 Canada Glacier met/eddy correlation station.
 
The .dat files contain raw data from the met station.

Concatenated, cleaned input files for data crunching are:

caa945ec

ecclean is a cleaned up version of caa945ec (i.e. with the start and end data checked and tossed if it's bad)
 
eccalc is calculated ec values for the entire period for which we have surface temperatures.

Contents of /metdata/caa956
 
*.reports.* files contain information about the contents of the raw data files caa956##.dat
 
caa956##.dat are the raw datafiles from the datalogger
 
caamet##.dat is the met portion of each raw file, corrected for gross data errors (ie. wind direction in caa95601.dat fixed; rnet calibration coefficient corrected; surface temp data in caa95610.dat replaces by bad data values) and pared down to only the fields of interest (ID#, vapor pressure and battery voltage omitted)
 
caaec##.dat is the ec portion of each raw file, corrected for gross data errors (ie. for runs without the EC instruments, H and LE have been replaced with bad data values) and pared down to only the fields of interest (H and LE) LE is still off by a factor of 5.
 
caa956met and caa956ec are concatenated files covering the entire season. These are input for IDL; see /programs/caa956. Note: out-of-range values are used when data is not available (6999).

ecclean is the cleaned eddy correlation data (based on windspeed, pressure, .....). Cleaning was done using ecclean.pro, an IDL program in ~/programs/caa956. This cleaning incorporates the multiplication by 5.
Note: since EC data is only available for selected runs, out-of-range values are used when data is not available (6999).
 
eccalc.dat is calculated eddy fluxes based on wind speed, temp and rh at the surface and approximately 2m height in the air. See IDL program ~/programs/caa956/eccalc.pro.
 
caa956ec.cln is a version of caa956ec.dat in which LE has been multiplied by 5 to correct for the calibration error. This file, along with caa956met.dat, were submitted to the LTER data manager Sept. 16, 1997. They were accompanied by readme.caa956.submitted.
