Satellite sensors are instruments mounted on satellites that are used to collect data and information about the Earth's surface, atmosphere, and oceans. These sensors can capture images, measure physical properties such as temperature and moisture, and detect various environmental phenomena such as wildfires, deforestation, and pollution. Satellite sensors are essential tools for monitoring and studying the Earth's environment, climate change, natural disasters, and other phenomena from a global perspective. They provide valuable data for scientific research, resource management, weather forecasting, and disaster response.
