Second, based on the experiment study by using the VF921-256 spectrometer, some characteristic parameters, such as aerosol spectral optical deepth, ozone column content, diffuse-to-global irradiance ratio and aerosol size distribution were retrieved, which are necessary to OAE.

Features of the aerosol optical depth of Beijing under the classification of the surface visibility.;

With Langley method, the data is anlyzed to get aerosol optical depth from 350 nm to 2500 nm.

The data measured with sun photometer CE318 are used to culculate the aerosol optical depth(AOD) in Urumqi during the period from April 2002 to March 2003.

Modulation on widening photonic forbidden band of one-dimensional photonic crystal by optical thickness;

The observation and analysis of atmospheric aerosol optical thickness over Beijing Area;

Effects of particle concentration and optical thickness on flame temperature field reconstruction;

Experiment of cloud optical thickness retrieval using SCIAMACHY instrument in oxygen A-band channel;

In this paper, we present a ground based retrieval method for determining the cloud optical thickness and effective particle radius and discuss the impact of cloud inhomogeneity on.

The cloud optical thickness, cloud particle effective radius and cloud top temperature are important parameters to determine cloud radiative properties, and it’s absolutely necessarily to make use of satellite data to get a worldwide information.
