PyScanCf – The Open Source Python based Library for Indian Meteorological Department (IMD) Doppler Weather Radar Datasets. This package provides a Python framework for working with single sweep radar data, from which sophisticated workflows can be constructed and used as input to Python based open-source softwares for processing radar data like as Py-ART, and Wradlib.
Pyrad is a real-time (and off-line) data processing framework developed by MeteoSwiss and MeteoFrance. The framework is aimed at processing and visualizing polar data from individual weather radars as well as composite Cartesian products both off-line and in real time. It is written in the Python language.
It is capable of ingesting data stored in the most common radar data formats, e.g. C/FRadial, ODIM, Rainbow, NEXRAD level-2 among others.
rainymotion is a Python library for radar-based precipitation nowcasting based on optical flow techniques. The main idea is to provide a stack of open models which can serve as a transparent benchmark for further development of nowcasting techniques. An extensive verification study in Germany has shown that the
rainymotion models based on Dense optical flow are at least equivalent if not superior to state-of-the-art operational nowcasting techniques.
pysteps is a community that develops and maintains an easy to use, modular and open source python framework for precipitation short-term ensemble prediction systems.
The Python ARM Radar Toolkit, Py-ART, is an open source Python module containing a growing collection of weather radar algorithms and utilities build on top of the Scientific Python stack and distributed under the 3-Clause BSD license. Py-ART is used by the Atmospheric Radiation Measurement (ARM) Climate Research Facility for working with data from a number of precipitation and cloud radars, but has been designed so that it can be used by others in the radar and atmospheric communities to examine, processes, and analyse data from many types of weather radars.
BALTRAD offers software for exchanging weather radar data in real time, and processing data using a common “toolbox” of algorithms. The data exchange functionality can be used stand-alone, as can the toolbox. While the focus is on creating an operational system, the design is also intended to help bridge the gap between research and operational communities.

wradlib was one of the first open source software solutions to support all essential steps of the weather radar processing chain. Since 2011, wradlib has evolved to be a professional solution for interactive weather radar data analysis and operational processing, with a large international user community in academia, government agencies, and the private sector. The user forum with more than 170 active members from all around the world provides an agile platform for exchange and support.
This tools enable ArcGIS to order, download and visualize Level II and Level III data in vector and raster formats.
This software provides Python functions that will estimate turbulence from Doppler radar data ingested via Py-ART. Specifically, this software will estimate the cubic root of eddy dissipation rate, given input radar data containing reflectivity and spectrum width. Can be done on an individual sweep basis or by processing a full volume at once. If the latter, a new turbulence field is created within the Py-ART radar object. The turbulence algorithm is based on the NCAR Turbulence Detection Algorithm (NTDA), adapted to work with a single radar.
This projects creates a Linux Virtual Machine image (VM) with a number of open source weather radar software packages (BALTRAD, Py-ART, Radx, RSL, and wradlib) which can be run using VirtualBox on a number of host OSes.
The creation of this VM has been tested on Ubuntu 12.04 and Mac OS X 10.9 hosts running vagrant 1.5.4. Other host should be supported if a recent version of vagrant (1.3+) and VirtualBox can be installed.
MultiDop is a Python-based interface between the C-based DDA code developed at University of Oklahoma and the Python Atmospheric Radiation Measurement Radar Toolkit (Py-ART) software developed at Argonne National Lab. Use this software to perform 3D wind analyses using 2-3 independent Doppler radars.
The National Oceanic and Atmospheric Administration (NOAA) regularly produces national 3D radar reflectivity mosaics via its Multi-Radar/Multi-Sensor (MRMS) system. These mosaics are wonderful for storm and precipitation analysis and research, but they are distributed in odd formats that NOAA is ever changing. Sometimes you just want to read a file and make a plot! This is what MMM-Py is for. With it, you can read any version of the MRMS radar mosaics, past or present, and you can analyze, plot, subsection, and output custom mosaics of your own, which MMM-Py can ingest later. MMM-Py is free and open source. It is capable of producing publication-ready figures and analyses, but it also can do quicklook plots so you can check out the cool storm that just happened.
