DOI
Coverage Status

PyDisdrometer is a Python package to process disdrometer files. It currently is capable of reading several different types of disdrometer formats, with more being added regularly. It currently supports the following functionality:

  1. File Reading
  2. Microphysics Estimation
  3. T-Matrix Scattering of Radar Parameters
  4. QPE Relationship Estimation.

It currently supports OTT Parsivel disdrometers, Joss Waldvogel Disdrometers, 2DVD files, and HVPS and 2DS airborne disdrometers.

Author: Joseph C. Hardin

Usage

An quick example of using the pydisrometer package to read in a parsivel data file and calculate radar scattered parameters is:

dsd = pydisdrometer.read_parsivel(filename)

dsd.calculate_radar_parameters() 

If using NASA Ground Validation Parsivel Disdrometer Data from the IFloodS campaign, usage is

dsd = pydisdrometer.read_parsivel_gv(filename, campaign='ifloods')

The scattered fields will be stored in the fields dictionary of the dsd object. So to plot the reflectivity one can run

plot(dsd.time, dsd.fields['Zh']['data'])

For more information, please see the examples in the Notebooks directory. Additionally you can find some initial documentation at PyDisdrometer Documentation

Requirements: This library currently requires the normal scientific python stack(numpy+scipy+matplotlib) It also requires the PyTMatrix Package.

We welcome contributions from all users. Please see the examples in Notebooks for a more indepth guide on how to use PyDisdrometer.
