Description

NEXRAD Level II weather radar data converted into a FAIR-compliant, analysis-ready, cloud-optimized (ARCO) format using Zarr v3 and Icechunk V2. The dataset is hierarchically organized by Volume Coverage Pattern (VCP) and radar sweep, enabling efficient time-series access to polarimetric radar variables without downloading and processing individual Level II files.This dataset has been transformed and optimized for cloud-native analysis by AtmoScale.

Temporal coverage: January 1, 2015 to present.
Radar site: KLOT, serving the Chicago, Illinois region.
Available variables: Reflectivity (DBZH), differential reflectivity (ZDR), copolar correlation coefficient (RHOHV), differential phase (PHIDP), radial velocity (VELOCITY), and spectrum width (WRADH).

Update Frequency

New volume scans are added continuously as data becomes available.
