Extended reference scenarios (ERS) files (including NLTE input and uncertainty perturbations)

Extended reference scenarios (ERS) files (including NLTE input and uncertainty perturbations) for CAIRT studies.

The dataset includes essentially all the atmospheric input (based on ERS https://zenodo.org/records/10022129) required to perform the GRANADA NLTE and KOPRA radiance simulations used in the CAIRT tomographic linear error analysis. This includes the input for unperturbed and perturbed NLTE and radiance simulations, the latter referring to perturbations of atmospheric parameters (CO2, O, T>120 km) and NLTE kinetic parameters. 

The data files are ascii files with the following naming __[_ngt][_hs][_hv][_].dat with parameters = pT, vmr, npar, ratio; _ngt for night (day has no suffix); _hs for ‘high solar’ (low solar has no suffix); _hv for high volcanic aerosol load (low volcanic has no suffix); refers to all perturbed atmospheric and NLTE parameters assessed in the error calculations (unperturbed has no suffix).  

parameter=ratio are the NLTE population files produced by GRANADA and read by KOPRA

parameter=pT are pressure and temperature as in ERS (https://zenodo.org/records/10022129) 

parameter=vmr includes vmr profiles of the ERS, but has in addition vmr profiles that are required for NLTE modeling (i.e., OH, HO2, N4S, N2D, H, O1D). It also includes some additional minor species not provided in the ERS which have been considered in the KOPRA radiative transfer calculations. Data sources for these profiles are specified within the files.

parameter=npar are photolysis rates needed for the NLTE calculations, computed with the MIPAS preprocessor (invoking TUV).
