Information Technologies in Remote Sensing of the Earth

The work is devoted to the problem of obtaining estimates of the height of ash, which was erupted into the atmosphere as a result of an explosive eruption of a volcano, using satellite data. The main ways to solve the problem are described. The work describes the possibilities of estimating the height of a volcanic ash cloud based on various satellite data in the information system of remote monitoring of the activity of volcanoes “VolSatView”. Two possibilities are described for obtaining an estimate of the heights of top cloud of ash: an estimate using meteorological forecast data and an estimate based on a comparison of observations from low-orbit and geostationary satellite systems. It is told about the main advantages and disadvantages of the implemented methods. An estimate of the measurement accuracy of the described technologies is also given.
