RF04 – the day we were waiting for

It’s not a surprise, that when you are looking for clouds to measure, it is very likely that you find them as well at the airport you plan to operate from. That’s what we had to deal with today. But pilots were convinced that it was doable, we did it, and it turned out to be the day that you do not want to miss.

It has always been the plan to stay local and find a good cloud deck to test different radar settings and get the first real differential absorption signal from the two GRaWAC channels. We found suitable clouds East of Kiruan on a 100 nm North-South leg that we followed four times before being back at Kiruna after about 4.5 hours. The data we collected look beautiful and should be the ones we needed to make this campaign a full success.
