7.2 sum_tran.for 

This is an improved version of sum_srad.for. This routine allows analyzing the hourly SAMSON radiation data more comprehensively. However, the analysis of the climate variables as available in the same files has been dropped. However, the analysis of the transmittance has been improved, enabling the sun-angle correction of transmittance (and thus unlinking the transmittance from the current sun angle). There is a free available version of the hourly SAMSON data available on the web. This is a reduced version of the SAMSON-CD data, containing only the pure radiation data, but lacking the other climate variables. Sum_tran.for is specifically suited to analyze this data as well since it does not assume include climate variables. Do not input SAMSON data into this program if the data has been extracted using the tools provided on the CD. The extraction tool saves the data in a slightly different format, which is not compatible with sum_srad.for. If data is downloaded from the Web, simply decompress the data an follow the instruction below to analyze the data.

The description of this Program is not finalized, yet.
