abstract = "Amazon forests play a fundamental role in the global carbon
balance as a carbon sink, but temperature elevations and frequents
extreme events as droughts and floods could make the forests a
source of CO2. Local atmospheric measurements of greenhouse gases
are needed to better understand how forest will respond to climate
change. The lower-troposphere greenhouse gas (GHG) monitoring
program over Brazilian Amazon Basin, has been collecting biweekly
GHGs vertical profiles in four sites since 2010. We aim to
understand the relationships between local deforestation and CO2
aircraft measurements in the Brazilian Amazon. We calculated
annual deforestation (using the Amazon Deforestation Calculation
Program - PRODES), land use and cover change data (using the
Brazilian Institute of Geography and Statistics - IBGE) and fire
data (using the Fire Monitoring System) in each annual influence
area at the four flight measurement sites of the Brazilian Amazon
from 2010-2017 (and also in the mean influence area of all years
by sites). We found that when we see total deforestation, it has a
relationship with global CO2 emissions in the Brazilian Amazon
biome. Fire has a strong relationship in the drought years, mostly
in 2012. Looking at each site, we found specific correlations with
deforestation, fire and land use. The biggest challenge was to
compare spatial analyzes of land use change and fire with punctual
data of airplane GHGs measurements. This study will contribute in
our understanding of anthropogenic activities over the Amazon
forest in a changing climate.",
