Modeling of aerosol and cloud optical depth

2011 IEEE Colloquium on Humanities, Science and Engineering, 2011
We have applied regression model together with statistical test, Pearson Correlation, to examine the relationships between aerosol optical depth (AOD), cloud optical depth (COD) and water vapor retrieved by Moderate Resolution Imaging Spectrometer (MODIS) in 2009 over Malaysia.

Long-term aerosol optical depth trend over Iran and identification of dominant aerosol types.

Science of the Total Environment, 2020
The paper focuses on analysis of long-term changes of aerosol optical depth (AOD) over Iran. It describes contributions of dominant aerosol in the aerosol load over Iran covering the period 1980-2018.

Review of aerosol optical depth retrieval using visibility data

, 2020
Both ground and satellite observation of aerosol are short of long-term and wide covering data. Aerosol optical depth (AOD) retrieved by visibility data can partly make up the lack of long-term aerosol observation data.

Fast Aerosol Optical Depth Retrieval from MODIS

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
Aerosol optical depth (hearafter called AOD) is an important geophysical parameter, and its retrieval from satellite data are both data and computationally intensive. This paper presents the implementation of parallel AOD retrieval from the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data, based on IBM System Cluster 1600 deployed ...

Aerosol Optical Depth Characterization in Middle and Polar Latitudes

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
The Aerosol Optical Depth (AOD) is a very important atmospheric parameter which knowledge will help to understand the atmospheric processes and to propose different scenarios related with climate change. AOD plays a main role in the energy radiation balance in the atmosphere and in the aerosol radiative forcing. In this paper an analysis of time series

Multi-sensor data assimilation of aerosol optical depth

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
As a result of increasing attention paid to aerosols in climate studies, numerous global satellite aerosol products have been generated. There exists, however, an outstanding problem that these satellite products have substantial discrepancies, that must be lowered substantially for narrowing the range of the estimates of aerosol's climate effects.

Aerosol optical depth in Northern Jordan

Renewable Energy, 1993
Abstract The depletion of the solar beam in northern Jordan is investigated during the two summer periods of 1990 and 1991. This paper discusses the effect of atmospheric constituents on the solar beam with the emphasis on the effect of aerosol optical depth.

Variability of aerosol optical depth and aerosol forcing over India

Advances in Space Research, 2006
Abstract Over the Indian continent, population is growing day by day and it is expected that soon India will become one of the world’s most populated countries. With the growing population, industrialization and urbanization, the aerosol loading in India is increasing that has significant impact on the weather/climatic conditions.
