NOTE** 3DRTMA data is being populated in the RRFS bucket under the prefix 3DRTMA and diag. The content provided supports model development. These are not yet operational NWS products and should not to be relied upon for operational purposes. This web site is not subject to 24/7 support, and thus may be unavailable during system outages.
The Rapid Refresh Forecast System (RRFS) is the National Oceanic and Atmospheric Administration’s (NOAA) next generation convection-allowing, rapidly-updated ensemble prediction system, currently scheduled for operational implementation in 2024. The operational configuration will feature a 3 km grid covering North America and include deterministic forecasts every hour out to 18 hours, with deterministic and ensemble forecasts to 60 hours four times per day at 00, 06, 12, and 18 UTC.The RRFS will provide guidance to support forecast interests including, but not limited to, aviation, severe convective weather, renewable energy, heavy precipitation, and winter weather on timescales where rapidly-updated guidance is particularly useful.
The RRFS is underpinned by the Unified Forecast System (UFS), a community-based Earth modeling initiative, and benefits from collaborative development efforts across NOAA, academia, and research institutions.
This bucket provides access to real time, experimental RRFS prototype output.
rrfs_a/rrfs_a.20230428/12/control contains the deterministic forecast initialized at 12 UTC on 28 April 2023. Users will find two types of output in GRIB2 format. The first is:
rrfs_a/rrfs_a.20231214/00/mem0001 contains the forecast from member 1, and
rrfs_a/rrfs_a.20231214/00/enspost_timelag contains the ensemble products.
