Working with Vertically Pointing Radar Data Using
This notebook will walk through how to utilize existing packages in the Python ecosystem (
hvPlot) to visualize data from a vertically pointing Ka-band radar.
By the end of this notebook, you will learn how to create the following visualization:

We are using data from a snow storm on 14 March 2022.
Ka-band ARM zenith radar (KAZR) Instrument#
An image of the KAZR radar collecting the data is shown below:
From the official ARM KAZR Documentation, “The Ka-band ARM zenith radar (KAZR) remotely probes the extent and composition of clouds at millimeter wavelengths. The KAZR is a zenith-pointing Doppler radar that operates at a frequency of approximately 35 GHz. The main purpose of this radar is to determine the first three Doppler moments (reflectivity, vertical velocity, and spectral width) at a range resolution of approximately 30 meters from near-ground to nearly 20 km in altitude.”
