The understanding of the local mechanisms leading to ozone depletion has improved, the information contents of space radar images has been understood, future environmental monitoring procedures have been established.
The study of atmospheric conditions has been successfully established, improved, performed and evaluated with respect to ozone content.
A comparison of the data obtained in site (ozonometer M-124) and satellite (TOMS/Earth Probe) measurements of total ozone has been carried out. After smoothing down both time series of total ozone were got close, statistically relevant level of correlation between data sets became 0,8. Relationships of total ozone with main meteorological characteristics and changes of atmospheric circulation show circumstantially very well the mechanism of ozone transfer.
Texture analysis of single-sideband images ERS1/2 & JERS has shown that texture characteristics by data content of results can be divided in the following two groups:
- Variations, average values and range of values in L-band make it possible to clearly isolate forest and non-forest areas; forest boundaries can be seen here and there on winter images in C-band, but absolutely undiscernible on summer images;
- Homogeneity, contrast, entropy, correlation, etc do not almost depend on the type of earth covers: forest, fields, water table are absolutely indiscernible with a rare exception.
The compiled maps showing the coefficient of backscatter will form an integral part of the radio-metrical databank on the Baikal region in microwave bands now being established. They will also be used as the basis for modeling radio signal scatter mechanisms, as well as for joint analysis of ground and space data.
