Space-based CO2 measurements have become an important capability in support of climate studies and to inform policy decisions. This intermediate, three-part webinar series will build on the previous CO2 training from 2022, providing a more in-depth review of OCO-2 and OCO-3 measurements along with demonstrations of case-studies. The latter will focus on how to read, visualize and interpret the data, how to account for quality flags in an analysis, how to use the data from the OCO missions to analyze impacts of an El Niño event on atmospheric CO2 and carbon sources and sinks, and how to examine spatial variations of CO2 over a metropolitan area. The demonstration will be conducted using Jupyter Notebook.

This training is also available in Spanish.

(2024). ARSET - Applications of Carbon Dioxide Measurements for Climate-Related Studies. NASA Applied Remote Sensing Training Program (ARSET).

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

  1. Identify the characteristics and limitations of the NASA Orbiting Carbon Observatory, OCO-2 and OCO-3 XCO2 measurements.
  2. Access and download data through the Distributed Active Archive Center (GES DISC), and open and visualize XCO2 data from OCO-2/OCO-3 in GES DISC Earthdata.
  3. Interpret XCO2 data from OCO-2/OCO-3 for global, regional, and local scales.
  4. Assess the  level of confidence to place in XCO2 measurements using the quality flags incorporated into each dataset.
  5. Analyze OCO-2 data for assessing the impacts of  an El Nino event on Level 2 CO2 concentrations and Level-4 fluxes over tropical regions. 
  6. Analyze OCO-3 data for assessing the variations in Level-2 CO2 concentrations over a metropolitan area.
