Review technologies that help us monitor the pulse of the planet. Learn about systems that directly measure carbon dioxide and methane emissions from both natural sources like wetlands and permafrost and human-made sources like agriculture and fossil fuels. Study how modern technologies - drones, satellites, aerial systems - are revolutionizing the way we measure carbon emission from energy production and use. Petroleum and Geosystems Engineering 379 (Topic: Global Carbon Monitoring Sys) and 379 (Topic 22) may not both be counted.
