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:** 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).

The High-Resolution Rapid Refresh (HRRR) is a NOAA real-time 3-km resolution, hourly updated, cloud-resolving, convection-allowing atmospheric model, initialized by 3km grids with 3km radar assimilation. Radar data is assimilated in the HRRR every 15 min over a 1-h period adding further detail to that provided by the hourly data assimilation from the 13km radar-enhanced Rapid Refresh.

The Multi-Year Reanalysis of Remotely Sensed Storms (MYRORSS) consists of radar reflectivity data run through the Multi-Radar, Multi-Sensor (MRMS) framework to create a three-dimensional radar volume on a quasi-Cartesian latitude-longitude grid across the entire contiguous United States. The radar reflectivity grid is also combined with hourly forecast model analyses to produce derived products such as echo top heights and hail size estimates. Radar Doppler velocity data was also processed into two azimuthal shear layer products. The source radar data was from the NEXRAD Level-II archive and the model analyses came from NOAA's Rapid Update Cycle model. Radar reflectivity was quality controlled to remove non-weather echoes and the data set was manually quality contolled to remove errors as revealed through inspection of dai[...]
The NOAA Multi-Radar/Multi-Sensor System (MRMS) integrates data from multiple radars and radar networks, surface observations, numerical weather prediction (NWP) models, and climatology to generate seamless, high spatio-temporal resolution mosaics at low latency focused on hail, wind, tornado, quantitative precipitation estimations, convection, icing, and turbulence.

The ERA5 archive provides a comprehensive record of global weather and climate from 1940 to present,
with multiple temporal aggregations for flexible analysis. This dataset is derived from
the ECMWF/Copernicus ERA5 reanalysis and includes daily means, 7-day rolling means,
and monthly/seasonal aggregations at 0.25°×0.25° global resolution. The Planette ERA5 archive stores
this data in cloud-native format (Zarr with icechunk) for efficient access and analysis.
The dataset includes essential atmospheric variables at both surface and pressure levels, enabling a
wide range of climate analyses, from daily weather patterns to long-term climate trends. Daily means
are computed by averaging hourly ERA5 data, while longer temporal aggregations are derived from these
daily means.
