TL;DR: The Rapid Refresh (RAP) as mentioned in this paper is an hourly updated assimilation and model forecast system, which replaced the Rapid Update Cycle (RUC) as an operational regional analysis and forecast system among the suite of models at the NOAA/National Centers for Environmental Prediction (NCEP).

TL;DR: The Rapid Update Cycle (RUC) as discussed by the authors is an operational regional analysis-forecast system among the suite of models at the National Centers for Environmental Prediction (NCEP), which is distinctive in two primary aspects: its hourly assimilation cycle and its use of a hybrid isentropic-sigma vertical coordinate.

TL;DR: An overview of the National Oceanic and Atmospheric Administration (NOAA) current operational smoke forecasting system (SFS) is presented in this article, which is intended as guidance to air quality forecasters and the public for fine particulate matter (≤2.5 μm) emitted from large wildfires and agricultural burning, which can elevate particulate concentrations to unhealthful levels.

TL;DR: In this article, a description of the RTMA applied to the 5-km resolution conterminous U.S. grid of the National Digital Forecast Database is given, and a brief discussion of the remapping of the NCEP stage II quantitative precipitation amount and NESDIS Geostationary Operational Environmental Satellite (GOES) sounder effective cloud amount to the five-km grid is offered.

TL;DR: A major revision to the Rapid Update Cycle (RUC) analysis/model system was implemented into operations at the National Centers for Environmental Prediction Center (NCEP) on 17 April 2002.
