FAQ-01: Which altitude regions of our atmosphere make up the region of interest for GRUAN?

“Upper Air” as used in the context of GRUAN refers to the combined troposphere and stratosphere. GRUAN places a strong emphasis on the upper troposphere/lower stratosphere region, which has the strongest climate relevance and a large variability. Measurement capabilities for different atmospheric parameters may be strongly altitude dependent and thus the abilities to achieve climate records at different altitude may vary.

    Of strongest climate relevance is the upper troposphere / lower stratosphere region, however, GRUAN target requirements for upper-air observations have been defined for the lower 40 km of the atmosphere (GCOS-112 and GCOS-134).
