The Rapid Update Cycle (RUC) weather forecast model was developed by the National Centers for Environmental Prediction (NCEP). On May 1, 2012, the RUC was replaced by NCEP's Rapid Refresh (RAP) weather forecast model. The RUC was designed to produce quick, short-term, weather forecasts using the most currently available observations. When it was first implemented in 1994, the model was run every three hours making forecasts out to 12 hours. By 2002, the RUC was run every hour, on the hour, producing 12-hour forecasts with a 1 hour temporal resolution. This dataset contains a 13 km horizontal resolution Lambert Conformal grid covering the Continental United States (CONUS) domain.

description: The Rapid Update Cycle (RUC) is an operational atmospheric prediction system comprised primarily of a numerical forecast model and an analysis system to initialize that model. Mesoscale Analysis and Prediction System (MAPS) is the research counterpart to the RUC. The RUC has been developed to serve users needing short-range weather forecasts. RUC runs operationally at the National Centers for Environmental Prediction (NCEP). The key features of RUC/MAPS include:

• high-frequency (every 1h) 3-d objective analyses over the contiguous United States
• high-frequency (every 1h) short-range weather model
• forecasts (out to 12 h) in support of aviation and other mesoscale weather forecast users assimilation of data from:
• commercial aircraft (relayed through ACARS – Aircraft Communications, Addressing, and Reporting System)
• wind profilers (404 and boundary-layer 915 MHz)
• rawinsondes and special dropwinsondes
• surface reporting stations and buoys
• RASS (Radio Acoustic Sounding System) – experimental
• VAD (velocity-azimuth display) winds from NWS WSR-88D radars
• GOES total precipitable water estimates
• SSM/I total precipitable water estimates
• GPS total precipitable water estimates
• GOES high-density visible and IR cloud drift winds
