MONITORING OF SHORT-LIVED SNOW COVERAGE BY RADAR AND OPTICAL DATA FROM SENTINEL-1 AND SENTINEL-2 SATELLITES
Journal Title: Ecological Engineering and Environment Protection (EEEP) - Year 2017, Vol 2, Issue 2
Abstract
Snow cover monitoring shows the great importance of this rainfall, the time-lines of the data from this event, and the spatial range and area of the observed object. The main aim of the presented research is to trace the use of different satellite data and approaches to track the dynamics of the development of the short-lived snow coverage. The subject of the study is short-lived snow coverage and its dynamics for 12 and 13 March 13, 2017 for Sofia city area, Bulgaria. The objects were analyzed and mapped according to ESA data, acquired by sensors Sentinel-1 SAR and Sentinel-2 MSI. Results have been obtained for quantitative changes of wet snow cover and its dynamics. The data used are with a high time-spatial resolution, which is imperative when it is need to study a short-lived event such as the wet snow coverage. The importance of this monitoring is that the remote sensing and reliable data required calculating models of climate, natural disasters and crashes have been obtained.
