“…The availability of ground-based data in addition allows effective and cost-effective monitoring of climate change in remote areas using SAR data. The SAR C-band enables the effective study of various objects [5][6][7][8][9][10][11][12][13][14][15] and especially wet snow and ice 3,4,[16][17][18][19] . Using SAR data, we studied the type of changes in the digital value of the reflected signal (Q) from various objects, including water in different phase states.…”

Data-driven innovations bring significant benefits to societies directly affected by global warming, as they underpin Global and European climate change policy. The application of a synchronous approach and interoperability of data from different sources for environmental monitoring in one of the most vulnerable to climate change regions in the World is the aim of this research. The research was conducted at Hannah Point peninsula, near the Bulgarian Antarctic base "St. Kliment Ohridski" on Livingstone Island, South Shetland Islands, Antarctica. The study area has high ecological importance for tracking the dynamics of processes not only on a local but also on a global scale. Various research sites with different groups of objects serving as environmental benchmarks were selected to be studied. The study objects include snow cover, wet snow, water, ice (including sea ice), herbaceous vegetation, lichens, mosses, soils, and sand. For each of the objects, ground GPS points were defined and in situ spectrometric measurements were performed. Data from an innovative automatic recording weather station (AWG), as well as various indicators and indices based on the spectral reflectance characteristics of the investigated objects in the optical and microwave range, were used. For their generation were used satellite images from Sentinel-1 and Sentinel-2 sensors of European Space Agency. Multiple optical indices were used to demonstrate the changes in the state of the objects for the summer season of 2022-2023. The data obtained and models used will serve the Bulgarian initiative for the construction of the Digital Twins, which is being on pilot developed in the Department of Aerospace Information (SRTI-BAS) and could be used by a wide range of scientists in the field of polar research as well as for climate change education. Open Data were used in this study, to promote the Open science policy and FAIR principles as much as possible.

With the increase of temperatures in the summer, the danger of self-ignition of landfills for household waste increases, because of the biochemical processes that take place inside them. The most recent example is the municipal landfill for non-hazardous waste near the town of Dupnitsa. The self-ignition started on July 23, 2021 and continued to smolder for almost a week, which led to a great danger of burning the area around it or poisoning the population. It is believed that one of the main reasons is the great depth of the accumulated waste. There is an urgent need to do quality control of most of the landfills for municipal waste in our country. Some of them are located next to major river arteries or international roads. Non-compliance with the requirements for maintenance, management and operation hides a serious potential for an ecological catastrophe. It is essential that stricter measures are taken and that these landfills are monitored. The aim of the present work is to reveal the possibilities and potential of aerospace data and to show different methods for processing, interpretation, and visualization. They can easily identify, map, and survey a waste disposal site. Optical images of the multispectral instrument (MSI) of the Sentinel 2 platform and radar (SAR) data from the Sentinel 1 platform of the Copernicus program of the European Space Agency were used. Thermal bands from the Landsat 5 - 7 (ETM) and Landsat 8 (OLI/TIRS) sensors of the Landsat program were used to calculate the land surface temperature. Satellite images have been orthogonized, and composite images between optical and radar data have been created for better visualization.
