Seven photometers of the aeronet network installed in the argentine territory: statistical analysis of the data and characterization of the aerosols

Abstract

On April 20th, 2017, a new sunphotometer of the AERONET - NASA network was installed inPilar, province of
Córdoba, at the dependencies of the National Meteorological Service in order to measure the aerosol load of the
region and especially to detect the biomass burning events that affect the center and north of the territory, and
subsequently arrive to the province of Buenos Aires and La Pampa due to the wind transport. Afterinstalling this
new instrument, the network has now 7 sunphotometerin the country, performing sistematic measurements. The
first equipment was installed at CEILAP-UNIDEF (MINDEF-CONICET) - CITEDEF, on October 17th, 1999 in
Buenos Aires. In this work the results obtained from a statistical analysis of the measurements from the 7 active
stations are presented: CEILAP-BA, CEILAP-RG, CEILAP-Comodoro, CEILAP-Bariloche, CEILAP-Neuquén,
Trelew and Pilar-Córdoba, to determine the monthly averaged values, aerosol optical depth tendencies, Ångstrӧm
coefficient and classification of the typical aerosol-suspended type for each station.
