Prognostic studies of the use of the Aqua satellite in the inference of the concentration of carbon monoxide in the atmosphere


The warmest three years in the history of Earth occurred in the last decade. It is probable that most of this warming stems from the emission, due to human activities, of gases which retain thermal radiation. These gases are also known as greenhouse gases. Important instruments that can be used to study the emission of greenhouse effect gases in the earth’s atmosphere are sounders on board space platforms. Currently, the Division of Satellites and Environmental Systems of the Weather Forecasting and Climate Studies Center (DSA/Cptec/Inpe) has made available the concentration of some greenhouse effect gases estimated using information from the Aqua satellite. This research Project aims to quantify the quality of the estimates of carbono monoxide, comparing them with field measurements, with data obtained from other satellites, with calibrated instruments recognized as “terrestrial truth” by the scientific community, in addition to the verification of the internal consistency through the comparison with results from models of air quality available from Cptec. It is important to observe that the quality of the remote soundings depends on the surrounding conditions imposed, as well as the appropriate choice of channels of the sounding system. In this context, we aim to contribute to the improvement in satellite products, restructuring algorithms in order to refine the inversion procedure under Brazilian climatic conditions and make available concentrations of carbon monoxide with quality control for researchers and users in general. In addition to scientific interest, it should be stressed that the better understanding of the emissions of greenhouse effect gases over Brazil is fundamental for the adoption of public policies which reduce biomass burning and deforestation, our greatest source of emissions.
