Replication Data for: Ground-based Profiling of Anthropogenic and Volcanic SO2 from Pandora Spectrometers

Each day subfolder therefore contains: (1) One netCDF file (yyyymmdd_Site_MMF_aerosol&SO2_profiles.nc) containing the MMF retrieval results. (2) YAML input file #1 used in the retrieval: yyyymmdd_Site_input1_O4&SO2_dscds.yml, which contains the measurement input data, including SO2 differential slant column densities (dSCDs), dSCD errors, etc. (3) YAML input file #2 used in the retrieval: yyyymmdd_Site_input2_ancillary_data.yml, which contains ancillary atmospheric data, including pressure and temperature profiles derived from ERA5 reanalysis, as well as additional parameters required by the retrieval.

This structure ensures that all inputs and outputs associated with a given site and day are collocated within a single directory for ease of use and reproducibility.
