CO2 monitoring from space is becoming an increasingly important and relevant capability in support of climate studies and to inform policy decisions. This introductory four-part webinar series will provide an overview of atmospheric carbon dioxide measurements 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, and the characteristics, limitations and validation of the measurement. There will be a discussion of the type of climate studies that such measurements can support. There will also be a practical session where participants will learn how to access, search, filter and display XCO2 data using Jupyter Notebook.


This training is also available in Spanish.

(2022). ARSET - Measuring Atmospheric Carbon Dioxide from Space in Support of Climate Related Studies . NASA Applied Remote Sensing Training Program (ARSET).

By the end of this training attendees will be able to:

  • Understand the characteristics and limitations of XCO2 measurements from space
  • Understand the type of climate studies that these measurements can support
  • Be able to open and visualize XCO2 data from OCO-2

This webinar series is intended for local, regional, federal, and non-governmental organizations from climate agencies to use CO2 remote sensing data in climate studies.
