In Manaus, capital of Amazonas, has begun this week the Intensive Airborne Experiment in Amazonia (Iara), a major component of the international scientific campaign GOAmazon Program. The experiment provides overflight of an aircraft for measurements of atmospheric chemistry and meteorological parameters.
The GOAmazon aims to understand in greater detail the impacts that air pollution in the city causes in the Amazon tropical system and their possible influences on regional and global climate.
Several devices have been installed at three different locations within a radius of 150 km from Manaus, while Iara will perform aerial measurements, using the plane Gulfstream 1 (G 1) from the U.S. Department of Energy (DOE). The GOAmazon brings together more than 100 researchers from Brazilian scientific institutions and the United States.
The Center for Weather Forecasting and Climate Studies (CPTEC) of the National Institute for Space Research (Inpe) participates as being responsible for Brazilian side of the mission Iara, and also with the Rain Theme Project, led by researcher Luiz Augusto Machado, whose scientific campaigns have were performed at six different locations, trying to characterize the different rainfall regimes in Brazil.
The whole infrastructure of the Rain project, including a last generation weather radar to measure several parameters within the storm clouds, is integrated into GOAmazon Program. INPE also participates with another four projects approved.
