20th Century Reanalysis
Using a state-of-the-art data assimilation system and surface pressure observations, the Twentieth Century Reanalysis Project is generating a six-hourly, four-dimensional global atmospheric dataset spanning 1871 to present to place current atmospheric circulation patterns into a historical perspective.
Hydrometeorology Testbed (HMT)
NOAA's Hydrometeorology Testbed (HMT) is a demonstration that focuses the
use of advanced observational and modeling tools on quantitative
precipitation estimation (QPE) and quantitative precipitation forecasting
(QPF) for the purpose of improving hydrologic forecasts and warnings. The
testbed approach will accelerate transitions from the research and
development community to operations, as described in NOAA's Strategic Plan
and recommended by the NOAA Hydrology Team's Science and Technology
Infusion Plan (STIP) and the U.S. Weather Research Program (USWRP).
