Caracterização e classificação das propriedades ópticas de aerossóis na atmosfera de Natal, Brasil
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Ambiental, 2016)
In this study the first characterization and classification of atmospheric aerosols over Natal (RN) based on the presented optical properties is envisioned. A Cimel solar photometer was used for obtaining the Aerosol Optical ...
An improved aerosol optical depth map based on machine-learning and modis data: Development and application in South America
(Taiwan Assoc Aerosol Res-taar, 2017-06)
In zones where aerosol properties have been poorly characterized, satellite-based (MODIS) and ground-based (AERONET) aerosol optical depth (AOD) values typically differ. In this work, we use machine-learning based methods ...
Multifilter rotating shadowband radiometer calibration for spectral aerosol optical depth retrievals over Sao Paulo City, Brazil
(OPTICAL SOC AMER, 2008)
Multifilter rotating shadowband radiometer (MFRSR) calibration values for aerosol optical depth (AOD) retrievals were determined by means of the general method formulated by Forgan [Appl. Opt. 33, 4841 (1994)] at a polluted ...
Satellite Retrievals of Aerosol Optical Depth over a Subtropical Urban Area: The Role of Stratification and Surface Reflectance
(2014)
We explore the relationship between satellite retrievals of aerosol optical depth (AOD) and surface aerosol mass
concentrations over a subtropical urban area, namely, Santiago, Chile (33.5°S, 70.6°W, 500 m.a.s.l.). We ...
Evaluación de aerosoles troposféricos del AMCM por medio de imágenes de satélite GOES
(2019-08-08)
RESUMEN:
La evaluación de aerosoles urbanos vía percepción remota ha incrementado su interés debido a las evidencias del efecto de los aerosoles en la transferencia de la radiación solar, el clima, la calidad del aire ...
Regional representativity of AERONET observation sites during the biomass burning season in South America determined by correlation studies with MODIS Aerosol Optical Depth
(AMER GEOPHYSICAL UNION, 2009)
This paper presents an analysis of ground-based Aerosol Optical Depth (AOD) observations by the Aerosol Robotic Network (AERONET) in South America from 2001 to 2007 in comparison with the satellite AOD product of Moderate ...
Análisis de un año de mediciones con fotómetro solar en el noroeste del conurbano bonaerenseOne-year analysis of measurements with solar photometer in the northwest of great Buenos Aires area
(Asociación Física Argentina, 2020-11)
Este trabajo presenta un primer estudio fotométrico de la carga aerosólica en la zona noroeste del conurbano bonaerense, específicamente en el campus de la Universidad Nacional de General Sarmiento (UNGS) en Los Polvorines. ...
Espessuras ópticas de aerossóis de uma região rural do estado do Rio Grande do Sul comparadas com uma região industrial do Brasil
(Universidade Federal de Santa MariaBREngenharia de ProcessosUFSMPrograma de Pós-Graduação em Engenharia de Processos, 2012-04-30)
Aerosols are solid or liquid particles suspended in air, which directly and indirectly interact with solar radiation and can be monitored through its optical depth. The aims of this study was to analyze the time series of ...
A method to improve MODIS AOD values: Application to South America
(Taiwan Assoc Aerosol Res-taar, 2016-06-27)
We present a method to correct aerosol optical depth (AOD) values taken from Collection 6 MODIS observations, which resulted in values closer to those recorded by the ground-based network AERONET. The method is based on ...
