UV Products Description

Discussions are currently underway regarding the file format to be used within EUBREWNET for downloading UV data. The goal is for these files to be compatible with the WOUDC extended CSV format. Below is a proposed output format for EUBREWNET level 2 spectral UV data from Brewer #037 in Sodankylä.
