RegCM3 (Regional Climate Mode version 3)

Compared to previous versions, RegCM3 was more portable, easy to use, and aimed at simulating tropical climates, reflecting the greater emphasis placed by ICTP on fostering the growth of scientific research in developing countries.

Detailed Description

English {{currentDetailLanguage}} English

Quoted fromPal, Jeremy S., Filippo Giorgi, Xunqiang Bi, Nellie Elguindi, Fabien Solmon, Xuejie Gao, Sara A. Rauscher et al. "Regional climate modeling for the developing world: the ICTP RegCM3 and RegCNET." Bulletin of the American Meteorological Society 88, no. 9 (2007): 1395-1410. 

ICTP RegCM3 development encompasses efforts from a number of scientists worldwide. Some of the contributions were made by scientists from EDNs as a direct result of the RegCNET activities, such as the inclusion of the Massachusetts Institute of Technology (MIT) convection scheme and a dust module  (see below).  In this section, we first present a brief history of the RegCM system and then a description of new developments in RegCM3. The current release of RegCM3, as well as a beta version with features in testing, may be found at 

RegCM history. Table 1 lists the various dynamical and physical packages of successive versions of the RegCM system. RegCM3 is an integration of the main improvements that have been made to version 2.5  (RegCM2.5) as described in Giorgi and Mearns (1999). These improvements are in the representation of precipitation physics, surface physics,  atmospheric chemistry and aerosols,  model input fields,  and user interface.  In addition, the model code has been modified for parallel computing. An important aspect of  RegCM3  is that it is user-friendly and operates on a variety of computer platforms. To that end, substantial changes have been made to the preprocessing, running, and postprocessing of the model. Furthermore, RegCM3 has options to interface with a variety of reanalysis and GCM boundary conditions to provide a full suite of simulation options.
