This introductory webinar series will provide an overview of atmospheric CO2measurements from space with the OCO-2 and OCO-3 satellite missions. It will include a theoretical portion that will describe the instrument, how the measurement is made, & the characteristics of the measurement as well as the type of climate studies that such measurements can support. There will be a practical session where participants will learn how to access, search, filter & display XCO2 data using Jupyter Notebook.
