Jim, Hi
Just stumbled across your message here, I'm not a big user of Ice in Space, not really my thing, in fact looking for something else. I'm completing a project for my Masters on using remote sensing to measure light pollution. The opportunity to calibrate with ground measurements is missing from most of such studies. I hope you submit your data to any of the data collection sites you can find all the sites from this link
