Higher-resolution RUC available to NOAAPort and NOAA Family of Service users
Starting December 4, 2007, RUC (Rapid Update Cycle) gridded data became available at higher horizontal and temporal resolution to all NOAA/NWS data users via Family of Services and NOAAPort. These communication changes were accomplished by the NWS.
Although the RUC has been running internal to NOAA's National Centers for Environmental Prediction (NCEP) at 13-km resolution since 2005, RUC users were limited to degraded 20-km and 40-km resolution due to transmission bandwidth limitations. On December 4, RUC data became available at full 13-km resolution. Moreover, RUC forecast data are available at hourly output increments to 9-h duration at all hourly initial times and out to 12-h duration at 00, 03, 06, 09, 12, 15, 18, and 21 UTC.
The RUC was developed and has since been improved yearly by NOAA/ESRL in collaboration with NCEP. It is one of the NCEP operational modeling systems and is initialized at the highest frequency (1-h) of any of NCEP's forecast models. NCEP's Aviation Weather Center and the Federal Aviation Administration are primary users of analysis and forecast products from the RUC. Other users include forecasters at NCEP's Storm Prediction Center, NWS forecast offices, and the private sector.
This long-awaited change significantly increases usability of RUC data to NOAA users. It is a valuable contribution to NOAA's mission of serving society's needs for weather information and it supports commerce through contributing to the safety and efficiency of air transportation.
