Satellite retrievals are a method of extracting information about the Earth's atmosphere, surface, and various features from satellite observations. This involves analyzing data collected by satellites to create detailed images, measurements, and other types of information that can be used for a variety of applications such as weather forecasting, climate monitoring, and environmental research. Satellite retrievals typically involve complex algorithms and data processing techniques to derive accurate and meaningful information from the raw satellite data. Researchers in this field work to improve the accuracy and reliability of satellite retrievals and develop new techniques to extract valuable information from satellite observations.
