Py-ART 2.0

In preparation for version 2.0.0 of Py-ART, codes were standardized for consistency purposes as further defined in the Contributor’s Guide. These changes will break some users code as the API has changed. This guide will detail the changes for each module.

How to Try Py-ART 2.0

The Py-ART 2.0 release candidate can be installed directly from github - this is still a work in progress, feedback is welcome!:

pip install git+https://github.com/ARM-DOE/pyart@release/2.0

Input/Output (IO)

We now offer the option to use xradar for IO. See Reading Data: xradar and Py-ART for the full xradar-first reading guide, the supported-API table for pyart.xradar.Xradar/pyart.xradar.Xgrid, and a worked gridding example.

Correct

The dealias_fourdd algorithm has been removed given the now unsupported RSL library.

It is recommended that users move to the region-based dealiasing algorithm.

Graph

Colormaps have been moved to a dedicated package outside Py-ART, cmweather.

For example, visualizing our grid mentioned previously, it is recommended to install/import cmweather and change the colormap name from pyart_ChaseSpectral to ChaseSpectral

import cmweather

display = pyart.graph.GridMapDisplay(grid)
display.plot_grid(
    "reflectivity_horizontal", level=0, vmin=-20, vmax=60, cmap="ChaseSpectral"
)
