1. Remote sensing: Scientists use satellite data and other remote sensing technologies to monitor greenhouse gas emissions at a global scale. These technologies can provide information on the concentration and distribution of gases such as carbon dioxide and methane in the atmosphere.
2. Ground-based monitoring: Scientists also use ground-based monitoring stations to measure greenhouse gas concentrations at specific locations. These stations are equipped with instruments that can measure the levels of various gases in the atmosphere, providing valuable data for researchers.
3. Aircraft measurements: Scientists sometimes use aircraft to collect samples of air at different altitudes and locations. This allows them to study how greenhouse gas concentrations vary in the vertical and horizontal dimensions, providing important insights into sources and sinks of emissions.
4. Ocean monitoring: Oceanographers also monitor greenhouse gas emissions by studying the exchange of gases between the atmosphere and the ocean. This involves measuring carbon dioxide levels in seawater and studying how ocean currents transport gases around the globe.
5. Flux towers: Scientists use flux towers to monitor greenhouse gas emissions from specific ecosystems, such as forests or wetlands. These towers measure the exchange of gases between the vegetation and the atmosphere, allowing researchers to understand how different types of ecosystems contribute to overall emissions.
