  1.    Third-Generation Regional Climate Model (RegCM3)

Pal, et. al, 2007:  Regional climate modeling for the developing world:  The ICTP RegCM3 and RegCNET.  Bulletin of the American Meteorological Society.  88, 1395-1409

RegCM3 is maintained here at MIT in the Eltahir Group as well as at ICTP.  Recent improvements made to the model in the Eltahir Group include the addition and improvement of subcloud layer evaporation schemes (Kuo, SUBEX)  [Marcella and Eltahir, 2008].  Also, current work is being completed in improving the dust module by including subgrid variability in dust emission parameters.

RegCM3 is coupled to following two land surface schemes:

  1. 1.   Biosphere-Atmosphere Transfer Scheme (BATS1e)

2.   Integrated Biosphere Simulator (IBIS) (coupled here in the Eltahir Group) [Winter et al, in review]

  1.   Hydrology, Entomology, and Malaria Transmission Model (HYDREMAT)   [Bomblies, et al, 2008]

    A coupled hydrology and entomology model has been developed to simulate in high spatial and temporal resolution the mechanistic links between environmental variables and malaria transmission. The hydrology model uses spatially distributed, satellite-derived vegetation and soil parameters. Excess precipitation is routed over this rough, infiltrating surface to simulate the formation and persistence of pools which allow malaria mosquito breeding. An agent-based entomology model simulating known behavior relevant to malaria transmission constitutes the link between hydrology and malaria.  In this way, environmental determinants of malaria transmission are simulated in detail.
