Welcome to the Weather Prediction Center's Hydrometeorology Testbed (HMT) Webpage, previously referred to as the FFaIR Webpage.
The 2023 FFaIR Experiment starts on June 5 and runs through August 11. The operating weeks of FFaIR are listed below. If you would like to participate we are still accepting participants, please sign-up via this form.
June 5 - 9 (virtual) June 12 - 16 (virtual) June 26 - 30 (hybrid) July 10 - 14 (virtual) July 31 - Aug 4 (hybrid) Aug 7 - 11 (virtual)
This is an experimental webpage that displays mainly experimental Models and Ensembles. Because of this, dataflow is sporadic, so if a model/ensemble is missing check to see if there is an earlier run. If the model/ensemble is still missing, we apologize and hope to have data available next time you visit.
The products shown on this webpage are NOT official NWS products. Information about WPC-HMT can be found here. If you are have any questions about the webpage or HMT please contact Sarah Trojniak (sarah.trojniak@noaa.gov) or Jimmy Correia (james.correia@noaa.gov).
We are in the process of including the RRFS ensemble products that will be tested in realtime during FFaIR. Hopefully these will be flowing consistantly come June 5. If you are interested in other developmental websites we support please see the Experiment Websites - Data Visualization tab in the HMT and NOAA Websites dropdown. Included in that is an interactive soundings viewer than displays HRRR and RRFSp1 soundings. The RRFSp1 refers to the deterministic RRFS that is currently in development as RRFSv1, this is also called RRFSa.
