چکیده
This paper considers the impact of doubled BC and OC aerosol emissions in the South Asia monsoon region using the ECHAM6-HAM model. This model has coupling between aerosol and convective processes but lacks important indirect effects and an interactive ocean surface. The authors find a systematic positive impact of doubled BC and OC emissions on the rainfall over India and eastern China. Since it does not account for the sea surface temperature (SST) feedback (e.g. Ganguly et al., 2012) and aerosol indirect impacts, this study should provide additional analysis that helps improve understanding of the impact of aerosols on the atmospheric state.

2. This study shows a heating rate of +0.003-0.005K/day (Line 434) due to carbonaceous aerosols near the tropopause, and it is only 1 to 2% of total atmospheric heating rate (âĹij0.2 to 0.5 K/day). What is the uncertainness of the atmospheric heating rates at the UTLS? Gettelman et al. (2004, Figure 4) suggests that the uncertainties from different radiative transfer models is on the order of +...

متن کاملIncrease in upper tropospheric and lower stratospheric aerosol levels and its potential connection with Asian pollution
Satellite observations have shown that the Asian Summer Monsoon strongly influences the upper troposphere and lower stratosphere (UTLS) aerosol morphology through its role in the formation of the Asian Tropopause Aerosol Layer (ATAL). Stratospheric Aerosol and Gas Experiment II solar occultation and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) lidar observations s...
متن کاملConvective outflow of South Asian pollution: A global CTM simulation compared with EOS MLS observations
[1] A global 3-D chemical transport model is used to analyze observations of carbon monoxide (CO) and upper tropospheric clouds from the EOS Microwave Limb Sounder (MLS). MLS observations during 25 August–6 September 2004 reveal elevated CO and dense high clouds in the upper troposphere over the Tibetan plateau and southwest China, collocating with the upper level Tibetan anticyclone. Model sim...
