We release the raw data for our processed ERA5-Downscale dataset, adopted from the original ECMWF ERA5 reanalysis data.

The data format for each sample in the climate_variables_v3.zarr is as follows:

{
  "timestamp": <UTC timestamp of the measurement>,
  "variables": {
    "temperature_2m": <2-meter temperature in Kelvin>,
    "precipitation": <total precipitation in meters>,
    "wind_u": <U-component of wind at 10m>,
    "wind_v": <V-component of wind at 10m>,
    "surface_pressure": <surface pressure in Pa>
  },
  "spatial_info": {
    "latitude": <latitude coordinate>,
    "longitude": <longitude coordinate>,
    "resolution": <spatial resolution in degrees>
  },
  "source": <the source of the climate data - ERA5, MERRA-2, etc.>,
  "processing_level": <raw, interpolated, or derived>,
  "meta": <additional metadata about the sample>
}

Some of the temporal gaps exist due to satellite observation limitations. These gaps are documented in the metadata.

*Note: Due to the large volume of raw climate data, some variables are stored at reduced precision. We maintain full precision for primary variables used in model training.
