Experiment name and it’s acronym Domain and Resolution Land-surface condition and duration of simulation run Details of Parameterization schemes used 1. RegCM4.0-BATS – FOREST (RBATS-F) (chem = true, idirect=1) 11°E-139°E, 34°S- 55°N (Cordex South Asia), ~ 90km (160x130x18, Normal Mercator map projection). The central point is located at 75°E and 15°N (approx.) •Afforestation experiment with thick forests • 1st January to 31st December 1987 •1st January 2009 to 31st December 2010 (a) Grell (1993) scheme with Fritsch and Chappell (1980) closure and Holstag (1990) PBL scheme. (b) Original ASCII encoded landuse map in the RegCM4 model altered to incorporate the design experiments. (b) The time step of model integration is 30 seconds, solar radiation is calculated is 30 minutes, absorption-emission is calculated is 18 hours and BATS is called in 600 seconds. (d) The lateral and lower boundary conditions for ground temperature (Tg), surface pressure (ps), sea surface temperature (SST) (except for soil moisture) were provided by the NNRP2 (Kanamitsu et al. 2002) 6-hourly data and Reynolds weekly sea surface temperature (SST) (Reynolds et al. 2002). 2.RegCM4.0-BATS – DECIDUOUS BROADLEAF (RBATS-DB) (chem = false) -do- •Afforestation experiment with deciduous broadleaf tree •1st January to 31st December •1st January 2009 to 31st December2010
