The archive is maintained by the Data Support Section of the Computational and Information Systems Laboratory] (CISL) at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado. The archive acquires, curates, preserves and disseminates an extensive list of over 700 data sets. Registration is free and open to the general public.
At the core of a radiative transfer model lies the radiative transfer equation that is numerically solved using a solver such as a discrete ordinate method or a Monte Carlo method. The radiative transfer equation is a monochromatic equation to calculate radiance in a single layer of the Earth's atmosphere.
The NCEP/NCAR Reanalysis is an atmospheric reanalysis produced by the National Centers for Environmental Prediction (NCEP) and the National Center for Atmospheric Research (NCAR). It is a continually updated globally gridded data set that represents the state of the Earth's atmosphere , incorporating observations and numerical weather ...
The Weather Research and Forecasting (WRF) Model [1] (/ ˈ w ɔːr f /) is a numerical weather prediction (NWP) system designed to serve both atmospheric research and operational forecasting needs, developed in the United States. NWP refers to the simulation and prediction of the atmosphere with a computer model, and WRF is a set of software ...
The Community Atmosphere Model (CAM) can also be run as a standalone atmosphere model. Its most current version is 3.1, while 3.0 was the fifth generation. On May 17, 2002, its name was changed from the NCAR Community Climate Model to reflect its role in the new system. [8]
The National Center for Atmospheric Research Land Surface Model (LSM) is a unidimensional computational model developed by Gordon Bonan that describes ecological processes joined in many ecosystem models, hydrological processes found in hydrological models and flow of surface common in surface models using atmospheric models.
Examples of reanalysis datasets include the ECMWF re-analysis, [2] the Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2), [3] and the NCEP/NCAR Reanalysis, [4] and the JRA-25 [5] [6] reanalysis conducted by the Japan Meteorological Agency.
Then, the model takes these guesses, and with the help of some surface observations, can create an objective analysis, using LITTLE_R. [8] RAWINS is an older version of LITTLE_R and thus LITTLE_R is more commonly used. Then INTERPF takes that data from RAWINS/LITTLE_R and REGRID to interpolate that data to the sigma coordinate explained above. [7]
