Description: |
    The Real-Time Mesoscale Analysis (RTMA) is NOAA NCEP's analysis of near-surface weather conditions. It combines observations with a model background using two-dimensional variational assimilation.

    These datasets have been translated to cloud-optimized Icechunk Zarr format by [dynamical.org](https://dynamical.org).

    - [NOAA RTMA analysis, virtual](https://dynamical.org/catalog/noaa-rtma-analysis-virtual/) - Hourly Real-Time Mesoscale Analysis (RTMA) operated by NOAA NWS NCEP on the native CONUS grid.
    - [NOAA RTMA-RU analysis, virtual](https://dynamical.org/catalog/noaa-rtma-ru-analysis-virtual/) - Real-Time Mesoscale Analysis Rapid Update (RTMA-RU) operated every 15 minutes by NOAA NWS NCEP on the native CONUS grid.
