Analysis of Aerosol Optical Thickness in Timisoara from AERONET Global Network Observations
نویسندگان
چکیده
Original scientific paper Aerosol particle thickness measurements were performed at the "Politehnika" University in Timisoara (Romania) during March 2011 using a CIMEL SUN solar photometer, as part of the global AERONET network. The aerosol optical thickness (AOT) represents a parameter of optical visibility in an atmospheric air column from the instrument towards the sun, affected by the presence of aerosol particles (e.g. smoke particles, desert sand). Precision analyses were performed to determine the types of aerosols present. Results were recorded during June 2011. The aerosol optical thickness (AOT) was increased on the 9th of June because of sands that drifted on air currents from Northern Africa to the western part of Romania.

The MODIS Aerosol Algorithm, Products and Validation
The MODerate resolution Imaging Spectroradiometer (MODIS) aboard both NASA's Terra and Aqua satellites is making near global daily observations of the earth in a wide spectral range (0.41 to 15 μm). These measurements are used to derive spectral aerosol optical thickness and aerosol size parameters over both land and ocean. The aerosol products available over land include aerosol optical thickn...

Atmospheric aerosol, as particulate matter suspended in the air, exists in a variety of forms such as dust, fume and mist. It deeply affects climate and land surface environment in both regional and global scales, and furthermore, lead to be hugely much influence on human health. For the sake of effectively monitoring it, satellite remote sensing data are used to inverse aerosol optical depth a...
متن کاملValidation of MODIS aerosol retrieval over ocean
[1] The MODerate resolution Imaging Spectroradiometer (MODIS) algorithm for determining aerosol characteristics over ocean is performing within expected accuracy. A twomonth data set of MODIS retrievals co-located with observations from the AErosol RObotic NETwork (AERONET) ground-based sunphotometer network provides the necessary validation. Spectral radiation measured by MODIS (in the range 5...

In this paper, a global validation package for satellite aerosol optical thickness retrieval using the Aerosol Robotic Network (AERONET) observations as ground truth is described. To standardize the validation procedure, the optimum time/space match-up window, the ensemble statistical analysis method, the best selection of AERONET channels and the numerical scheme used to interpolate/extrapolat...
متن کاملValidation of MISR Aerosol Optical Thickness Measurements Using AERONET Observations over the Contiguous United States
Aerosol optical thickness (AOT) data derived by the Multi-angle Imaging SpectroRadiometer (MISR) from Jan 2001 to Feb 2002 were compared with AOT measurements from 16 Aerosol Robotic Network (AERONET) sites over the contiguous United States. Overall, MISR and AERONET AOTs were strongly correlated (correlation coefficient = 0.81). Regression analysis showed that MISR AOT retrievals had a positiv...
