This directory includes Version 2 spectra and PDF files showing a comparison between corrected spectra and model calculations.

All data are zipped.

The column assignment of Version 2 spectra is a follows:

Column 1:	Wavelength in nm
Column 2:	Measured corrected global spectral irradiance in uW/(m2nm)
Column 3:	1/cosine correction (The product of column 2 and 3 are cosine-uncorrected measurements)
Column 4:	Modeled clear-sky global spectral irradiance in uW/(m2nm)
Column 5:	Contribution of the direct beam to the modeled clear sky irradiance in %. (0 means that all incoming radiation is diffuse)
Column 6:	Modeled global spectral irradiance considering clouds in uW/(m2nm). Note that ozone was set constant to 300 DU. No model values are given for wavelengths below 340 nm.
Column 7:	Contribution of the direct beam to the modeled "cloud" irradiance in %. (0 means that all incoming radiation is diffuse)
Column 8:	Time in UT in the format hours . fraction of hours
Column 9:	Solar zenith angle
Column 10:	Solar azimuth angle
Column 11:	Azimuth error corrected TSI measurements in Volt
Column 12:	1/(TSI cosine correction)


The filename convention is:

sByyhhmm.jjj

where
s 	= Site identifier (c=South Pole)
B 	= Indicator for Version 2 data
yy	= Year
hh 	= Hour (UT)
mm	= Minute
jjj	= Julian Day
