Atmospheric observations refer to the collection of data related to the Earth's atmosphere, including its composition, temperature, pressure, humidity, and other physical and chemical properties. These observations are crucial for monitoring and understanding weather patterns, climate change, air quality, and atmospheric phenomena such as storms and pollution. Atmospheric observations are conducted using a variety of methods and technologies, including satellite remote sensing, ground-based instruments like weather stations and radiosondes, and aircraft-based sensors. These observations help scientists track trends in atmospheric conditions over time, make predictions about future weather events, and determine the impacts of human activities on the atmosphere. Overall, atmospheric observations play a vital role in advancing our understanding of the Earth's climate system and in informing policies and decisions related to environmental protection and sustainability.
