This is a python module for calculating various statistics from the radiosondes launched during EUREC4A. The soundings of the following platforms can be handled as long as the data is provided in NetCDF files:

Barbados Cloud Observatory (BCO) Ronald H. Brown (RHB) Meteor (M161) Atalante (ATL) Maria S Merian (MSM)

The naming convention for the NetCDF files is of the form: {platform_abbreviation}_SoundingAscentProfile_*_{YYYYMMDD}_*.nc' {platform_abbreviation}_SoundingDescentProfile_*_{YYYYMMDD}_*.nc'

The module makes use of a python toolbox for atmospheric research called typhon, which is openly available under:

https://github.com/atmtools/typhon

The file utils.py is a module that contains functions to calculate various atmospheric properties based on the provided radiosonde data. This module is used in the 3 provided jupyter notebooks to plot and to calculate different kinds of statistics of radiosonde data, which shall here be briefly described:

soundings_one_platform_stats.ipynb:

• For a given platform and time period, calculate various atmospheric properties for each individual sounding.
• Calculate the mean, standard deviation, minimum, maximum and quantiles over the individual atmospheric properties calculated for each sounding.
• Plot a set of vertical profiles for all the soundings of the most prominent atmospheric quantities.

soundings_compare_platforms.ipynb:

• For a given day and time period, plot a map with the positions of each platform and the trajectories of the soundings.
• Plot vertical profiles of different quantities for all platforms.

soundings_temporal_evolution.ipynb:

• For a given platform and time period plot the temporal evolution of different quantities (relative humidity, wind speed, ...) with height.
