SNOW MAPPING

Satellite images serve as a vital source of information to understand and investigate different weather phenomena. As the climate changes, historical satellite images are analysed to better understand how weather conditions have changed over the years. This helps to understand weather dynamics that contribute to changes in climatic conditions making it possible to predict and monitor catastrophic events related to climate change such as droughts, floods and snow.
