Research theme area
This research is part of the RCGI project – 64 GHG project – D.1, which has the title: "Greenhouse gas emissions in the Amazon and data analysis system and services". In this project, a multidisciplinary team will build a computer system that integrates data associated with the emission of greenhouse gases in the Amazon, which integrate land use changes, remote sensing of greenhouse gases, meteorological parameters, forest degradation data, internal measures. in situ in soil and in fluxes and concentrations of greenhouse gases in the Amazon. The project will integrate land use change data from MapBiomas, INPE deforestation and fire detection systems, remote sensing and in-situ measurement of greenhouse gases data in an open access computational platform using machine learning and artificial intelligence techniques, with web access.

Abstract
Carbon fluxes in tropical forests are influenced by a set of meteorological variables
(temperature, precipitation, direct and diffuse radiation, cloud cover, etc.), as well as
atmospheric components such as aerosols, ozone and others. This proposal aims to study
the effects of changes in the meteorology, on the net carbon assimilation (Net Ecosystem
Exchange – NEE) by primary forest ecosystems in the Amazon. Aerosol measurements will
be made with MODIS, MISR and CALIPSO sensors, as well as new sensors such as ESA’s
Sentinel 5. Remote sensing measurements will be validated with NASA/AERONET network
solar photometer measurements and ground based measurements at the ATTO tower.
Cloud cover will be measured with CloudSat, precipitation with TRMM (Tropical Rainfall
Measuring Mission) and the radiation balance measured with the CERES (Clouds and the
Earth’s Radiant Energy System) sensor. Carbon fluxes will be measured using eddycorrelation
techniques on the ground, in the LBA program towers and also in the ATTO tower or derived from remote sensing using data from the OCO-2 satellite. Changes in temperature and relative humidity of the atmosphere due to the interaction of solar radiation with the high load of aerosols emitted from fires, will also be studied for several sites in the Amazon. In view of large-scale aerosol transport during fires, changes in carbon fluxes will be analysed across the Amazon region, where aerosols make important changes in the potential for forest ecosystems to absorb significant amounts of atmospheric CO2.
The combination of this large set of measurements will be integrated with a computational
Big Data approach and also using artificial intelligence and machine Learning algorithms.
The aim is to quantify the various drivers that control carbon fluxes in Amazonia.

Description
The applicant will contribute in line with the main objectives of the project:
Creation of databases for the spatial distribution of various meteorological components such as radiation, precipitation, cloud cover, water vapor column, liquid water content, precipitation, and vertical movements for all the Amazonia regions. Integration of these meteorological databases with patterns of land use change and greenhouse gas fluxes.
