Data used to initialize and evaluate CM1-LES simulations: Atmospheric sounding, vertical profiler Ka-band radar and BLTR.

The following files contains the data used to initialize and evaluate CM1-LES simulations.

The text file contains an atmospheric sounding recorded at 13:00 local time by the Instituto Geofísico del Perú in Huancayo, Peru. Essential variables from the sounding (altitude, potential temperature, specific humidity, and the u- and v-wind components) were interpolated to match the vertical grid spacing of the Cloud-Model 1 (CM1) by Steven Chavez. Chavez also added a line of surface values from local measurements according to the CM1 especifications (https://www2.mmm.ucar.edu/people/bryan/cm1/soundings/) , making the sounding fully ready to initialize a Large Eddy Simulation (LES) in CM1.

The netcdf files (.nc and .mmclx) contain daily wind data from the Boundary Layer and Tropospheric Radar (BLTR) vertical profiler and the hourly Ka-band vertical profiler radar data recorded by the Instituto Geofísico del Perú in UTC time at the Observatory of Huancayo, in Huancayo, Perú. These file were produced by the Instituto Geofísico del Perú and can be located also at https://pnaig.igp.gob.pe/climadata/. The list of variables and units of each netcdf file can be seen using the Matlab command ncdisp('filename'), to see an example please look at the attached Matlab Scripts.

The observatory of Huancayo is located at -75.33° longitude West and -12.03° latitude South and elevation of 3300 masl.

The Matlab scripts files to read the wind components (u,v,w) from the BLTR; the Equivalent Radar Reflectivity Factor (Ze), Linear De-Polarization Ratio (LDR) and Spectral Width from the Ka-band vertical profiler radar were elaborated by Steven Chavez.
