REMOTE SENSING FROM SPACE
Space-based observations provide unmatched spatiotemporal observations of the earth. We use multiple satellites to study methane, nitrogen oxides, carbon monoxide and carbon dioxide as well as surface hydrological properties (inundation and soil moisture). Some instruments we use include:

INSTRUMENT DEVELOPMENT/DEPLOYMENT
We actively work with instrumentation, with a particular focus on preparing instruments for deployment in challenging environments. We have specialized instruments for airborne measurements of ethane, methane, nitrous oxide, carbon dioxide, carbon monoxide, and water vapor.

AIRCRAFT CAMPAIGNS
Making observations from aircraft enables us to study emissions, uptake, chemical, and transport processes on scales ranging from local to global. We conduct this research on a range of platforms, from small propeller aircraft to larger platforms, such as the NSF/NCAR GV.

MODELING
To guide and interpret atmospheric observations, we use a variety of modeling tools, from simple box models to high-resolution lagrangian particle dispersion modeling and geostatistical inverse models.
