Retrieval coefficients for HATPRO observations during MOSAiC

Retrieval files required to run the IDL program MWR_PRO [1] script 'pl_mk_pol.sh' to process raw HATPRO brightness temperatures and retrieve integrated water vapour (IWV, also called prw), liquid water path (LWP, also called clwvi), zenith humidity profiles (hze), zenith temperature profiles (tze) and boundary layer temperature profiles (tel). The retrieval files contain the coefficients acquired via regression with linear only (tel) or also quadratic terms (prw, clwvi, hze, tze) based on Ny-Alesund radiosonde measurements. The coefficients have been determined by Nomokonova et al. [2]. [1]: Walbröl, Andreas. (2022).
