OCO-2 in orbit

I am a postdoctoral scholar in the Wennberg group at the California Institute of Technology. My primary research focuses on applications of the Orbiting Carbon Observatory 3 (OCO-3) instrument. I will be involved in validating it after it launches in 2019. Once it is operational, I plan to use it in conjunction with the exisiting OCO-2 instrument to study how the diurnal variation in plant respiration affects atmospheric CO2 concentrations.

My previous research focused on the development and application of space-based measurements of NO2, and led to the development of v3.0B of the Berkeley High Resolution (BEHR) NO2 product. During my Ph.D., I used the BEHR product along with other satellite datasets to study NOx emissions from lightning and the oxidative chemistry in urban plumes. I continue to be interested in the combination of satellite measurements with forward and inverse models to study anthropogenic and natural emissions of trace gases to the atmosphere and the chemistry that controls the ultimate fate of those trace gases.
