Dear all, thank you all for the great responses!
Specifically for the question after the first clear computer remote sensing RT paper, for now the price goes to Thomas Trautmann for Plass 1956, I think. Wow, so it is fair to say that this was amongst the very first applications that computers were used for. Best wishes, Stefan > On 26.
