Reply to comment by K. M. Lau and K. M. Kim on '"Elevated heat pump' hypothesis for the aerosol-monsoon hydroclimate link: 'Grounded' in observations?"
K. M. Lau and K. M. Kim Elevated heat pump aerosol-monsoon hydroclimate link in observations
2014/5/20
Lau and Kim‟s [2011, hereafter LK11] defense of the Elevated Heat Pump (EHP) hypothesis is weak. Nigam and Bollasina [2010, hereafter NB10] have assessed the viability of the EHP hyp...
Aerosol exposure versus aerosol cooling of climate: what is the optimal emission reduction strategy for human health?
Aerosol exposure aerosol climate the optimal emission reduction strategy human health
2010/10/11
Particles, climate change, and health have thought-provoking interactions. Air pollution is one of the largest environmental problems concerning human health. On the other hand, aerosol particles can ...

2010/10/11
A novel sub-micrometric size-resolved source flux function, explicitly defined as a function of the diatomaceous exudate concentration, was derived from the size distribution measurements and the esti...
Impact of Manaus City on the Amazon Green Ocean atmosphere: ozone production, precursor sensitivity and aerosol load
Manaus City the Amazon Green Ocean atmosphere ozone production precursor sensitivity aerosol load
2010/10/11
We used a Single Column Chemistry and Transport Model (SCM) to infer the urban pollution emission fluxes of Manaus City, implying observed mixing ratios of CO, NOx and VOC. The model can reproduce the...
