Data coverage
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).
