Temperature observation data from ground-based microwave radiometers and radiosonde observations across three sites.

The NetCDF (.nc) files contain groud-based Microwave Radiometer (MWR) temperature retrievals that have passed quality control checks for range validity, vertical consistency, and temporal consistency. Variables include height (height levels in meters), time (UTC), and T_MWR (retrieved temperature in degrees Celsius). The corresponding MATLAB (.mat) files provide radiosonde (RS) temperature observations for matched time periods. In each array, the first dimension represents the original RS height levels (ordered from lower to higher altitudes), and the second dimension represents time steps. Numeric identifiers in the filenames correspond to station IDs for the respective observation sites.
