What is Model Data?
North America - U.S., Canada, and northern Mexico
The RUC is a NOAA/ NCEP operational weather prediction system running every hour, out to at least 18 hours, comprised primarily of the following:
- A numerical forecast model (using isentropic-sigma hybrid vertical coordinate)
- An analysis/assimilation system to initialize that model
- Developed to serve users needing frequently updated short-range weather forecasts, including those in the US aviation community and US severe weather forecasting community.
- The Rapid Refresh (RR) is the next-generation version of the 1-h cycle system, planned to replace the current RUC by Aug-Sept 2011.
