AEROCLIMA - Direct and indirect effects of aerosols on climate in Amazonia and Pantanal

Projeto Temático FAPESP 08/58100-2 (2008 - 2013)

The proposal AEROCLIMA will work on an integrated strategy to enhance the knowledge on the direct and indirect effects of aerosols on climate for Amazonia and Pantanal regions. The idea is to reduce uncertainties on aerosol forcing trough an approach with detailed aerosol and radiation measurements in several sites, coupled with a modeling component with 1D, regional and global climate models approach. Remote sensing of aerosol and clouds will also help to provide the large scale distribution and characterization. Key aerosol properties such as aerosol size distribution, mass, composition, light scattering and absorption, CCN activity, will be measured for one year in each of 3 aerosol sampling stations: North of Manaus (pristine natural biogenic emissions), Alta Floresta (biomass burning aerosols) and Campo Grande at the Pantanal region. Intensive campaigns such as CLAIRE 2010 will use aerosol mass spectrometers and advanced instrumentation to better characterize aerosol properties. We will also have aerosol vertical profile with Raman Lidar measurements as well as 7 AERONET sun photometers and radiometers in continuous operation. Airborne measurements using an instrumented aircraft (INPE Bandeirante) will explore the large scale aerosol properties and distribution over Amazonia and Pantanal. The large scale will be observed with the use of MODIS (on both Terra and Aqua) and CALIPSO measurements. The modeling component will use CATT-BRAMS and WRF-Chem to study the regional aerosol forcing. LES models will be used to study aerosol-cloud interactions. Novel remote sensing instruments will be developed to measure cloud water phase, as well as droplet size distribution. The joint use of these tools will allow much better aerosol characterization that was done previously and the calculation and measurement of more accurate aerosol forcing, with sensitivity studies to investigate the most important parameters on the aerosol effects on climate.

This was our previous flagship project, which is now finished.
