abstract = "Between 2013 until 2015, Brazil's southeast region has been
affected by a strong drought event, generating disorders to the
population, mainly regarding to water supply at S{\~a}o Paulo
Metropolitan Area (SPMA). This research has the objective to
analyze the precipitation pattern observed at SPMA and to identify
possible relations with air pollution. We have used the aerosol
optical depth (AOD) data at SPMA during the summertime of 2013 to
2015 from AERONET and MODIS satellites. Trough the mean values of
AOD from MODIS between the years 2013 to 2015, it has been
observed higher AOD during August, September and October, with the
values of 0,11 (8% above average), 0,16 (55,44% above average) and
0,16 (55,44% above average), respectively. Comparing AOD from 2014
with the mean AOD from 2000 to 2015, there has been an increase of
27,76% in AOD in October. Also, higher AOD was observed during
2014, with maximum between August and October. Though it is usual
the occurrence of maximum AOD during the winter (April to
September), usually it is not common during October. This month is
characterized by the onset of the rainy season in the Central
Region of Brazil, and the AOD starts to decrease. Furthermore, it
was observed precipitation deficits in 2014, with strong
deviations from the long term mean associated with the persistent
drought since end 2013 to early 2015. In 2014, the total annual
precipitation observed at the official raingauge at S{\~a}o Paulo
city was 1253,3 mm, with a negative anomaly of 187,8 mm. In
October, the anomaly was -101,7 mm. Preliminary analysis suggest
AOD at SPMA is associated with precipitation patterns, possibly
associated with the reduction of the wet deposition. However, it
is not known if the decrease of precipitation is the cause or
consequence of the drought.",
