README.TXT - Description of flux station datafiles

Data from the energy flux station is provided in two separate sets of files.
	
The first consists of one file that includes all of the measurements made 
on the first (non-sonic) tower and in the soil subsurface. This data file 
is in comma separated variable (CSV) format with fixed length fields.  The 
data record covers the month of October and provides 5-minute averages. The 
filename is PSB2_FluxStation_Tower1_IOP#.csv where '#' specifies the IOP.
The columns in the file are:

	1:    Year
	2:    Month
	3:    Day
	4:    Hour (MST)
	5:    Minute
	6:    Battery Voltage
	7:    Air Temperature at 2 m (deg C)
	8:    Relative Humidity at 2 m (%)
	9:    Solar Radiation (W m-2)
	10:   Soil Temperature A at 2 cm (deg C)
	11:   Pressure (in. Hg)
	12:   Net Radiation (W m-2)
	13:   Soil Moisture, 2.5 cm (% by volume)
	14:   Soil Heat Flux, Plate 1, 8 cm (W m-2)
	15:   Soil Heat Flux, Plate 2, 8 cm (W m-2)
	16:   Soil Temperature B at 6 cm (deg C)
	17:   Soil Heat Flux, Plate 3, 8 cm (W m-2)
	18:   Soil Heat Flux, Plate 4, 8 cm (W m-2)

The second includes half hour GHG summary files that were automatically 
generated by the Licor SmartFlux EddyPro system. A subset of the data extracted 
from these half hour summary records is provided in the project database for the 
days encompassing each of the IOPs. These include the more basic meteorological, 
flux, and quality control data. The complete files contain more comprehensive 
records with 189 total fields and are available upon request. The filenames are 
PSB2_FluxStationi_Tower2_IOP#.csv where '#' specifies IOP. The column headers 
for data in the subset files are:
