NASA | Aqua AIRS: Visions of Weather and Climate

The video discusses the AIRS instrument on NASA's Aqua satellite, highlighting its role in improving weather forecasts and understanding climate systems. AIRS provides a 3D view of the atmosphere, aiding NOAA in enhancing weather predictions by six hours. It also helps in understanding the climate by studying water vapor and carbon dioxide, crucial for analyzing natural and human-induced climate change. The data reveals CO2's role in the greenhouse effect and tracks its global movement, uncovering unexpected emission sources in the southern hemisphere.

Describe the seasonal cycle of carbon dioxide as mentioned in the text.
