NEXRAD ARCO - atmoscale.ai Icechunk-Zarr
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](https://atmoscale.ai). - **Temporal coverage
