摘要

The optical properties of aerosols have an important meaning in atmospheric research issues. This work proposes a seasonal and inter-annual characterization of the Aerosol Optical Depth (AOD) at 500 nm through a transition region Pantanal, Cerrado (Cerrado characteristics) in the south central region of the State of Mato Grosso. AOD 500 nm data were acquired from the network AERONET 2001 to 2013. The daily values AOD 500 nm have a seasonal pattern, with minimum and maximum in the wet and dry seasons, respectively. The minimum values were mostly around to 0,02 in the wet season while the maximum values close to 5,23 in the dry season. Regarding the inter-annual characterization, it was found that is not a periodic behavior with large variations from year to year. The monthly averages of AOD 500nm were correlated with the monthly records of fire outbreaks in the State of Mato Grosso, however, there was no statistically significant correlation, which shows that this relationship exists, but it is not simple.
