OceanRAIN-M number concentration PSDs (m-3 mm-1) and OceanRAIN-R raw PSDs along with and precipitation microphysics and radar-related parameters. Both files contain 37 parameters in temporally discontinuous 1min-resolution for precipitation events only. The data source discriminates between measured (NAV, MET, ODM), observed (SYN) and calculated parameters (calculated). Note, that column 38-165 store the 128 values for the PSDs. The first lines in the OceanRAIN-M files contain a header providing the log-scale 128 bin size centers in mm.
