Background error modeling plays a key role in a variational data assimilation system. The National Meteorological Center (NMC) method has been widely used in variational data assimilation systems to generate a forecast error ensemble from which the climatological background error covariance can be modeled. In this paper, the characteristics of t...Institution National Center for Atmospheric Research - NCAR
In 2011, the National Oceanic and Atmospheric Administration (NOAA) began a cooperative initiative with the academic community, to help address a vexing issue that has long been known as a disconnection between the operational and research realms for weather forecasting and data assimilation. The issue is the gap, or more exotically referred to ...
The Common Community Physics Package (CCPP) is a collection of atmospheric physical parameterizations for use in Earth system models and a framework that couples the physics to a host model’s dynamical core. A primary goal for this effort is to facilitate research and development of physical parameterizations and experimentation with physics-dyn...Institutions National Center for Atmospheric Research - NCAR National Oceanic and Atmospheric Administration - NOAA University Corporation for Atmospheric Research - UCAR
