Observations of temperature inversions over central Arctic sea ice in summer
We analysed high‐resolution tethersonde sounding data from the drifting ice station Tara in the Arctic Ocean in April to August 2007 to (i) better understand the multiple processes affecting the generation and properties of Arctic air temperature inversions and (ii) to obtain insight into the vertic...
