Satellites and Climate Understanding

NASA has expanded its fleet of Earth-observing instruments to 80, with recent launches including the Global Precipitation Measurement (GPM) mission and the Orbiting Carbon Observatory (OCO-2). These missions aim to enhance understanding of precipitation and carbon dioxide's impact on global warming. Instruments on the International Space Station, such as RapidScat and CATS, provide valuable data on wind speeds and cloud formation. The upcoming SMAP mission will focus on soil moisture and the water cycle. Satellite data is crucial for weather forecasting, climate modeling, and aiding decision-making in agriculture and resource management.
