Recently, the Optimal Spectral Sampling (OSS) method was implemented in a development version of the Community Radiative Transfer Model (CRTM) at JCSDA. This presentation describes the way that the OSS is implemented in CRTM, and some preliminary evaluation of the performance of the CRTM-OSS in comparison with CRTM-ODPS method. One of the important benefits of the OSS method is its capability to simulate...
This paper describes numerical experiments conducted by using the meteorological model CALMET. The aim is to assess how the computational time of the model runs depends on user-defined parameters involved in the iterative procedure used by CALMET to solve the meteorological field. The influence of the weather conditions on the simulation time has been also evaluated.
MITgcm model is adopted probably first time for the western shelf region of the Bay of Bengal to model internal waves. Monthly climatological wind and density fields are considered in the model with real-time tides to generate internal waves in the region. The model simulations are compared with the actual observations available during 19–21 February 2012. Time series temperature data is collected...
The purpose of this paper is to introduce and evaluate a high-resolution (5km) atmospheric downscaling system. The NCEP-NCAR Reanalysis and the NCEP-DOE Reanalysis II are used to drive a 30 years multi-scale simulation. We report in this paper the different steps for the implementation of the downscaling strategy. Our system has been applied to the east coast of South America with a specific emphasis...
