About the Lecture:
The world’s nations are gathering to pledge targets for future greenhouse gas emissions. How well can we determine whether a nation is meeting its emission targets?
Gases are mixed rapidly, albeit incompletely, in the atmosphere. This rapid mixing confounds the problem of climate treaty verification. I will review the global carbon cycle, the activities that release CO2, and how the land and oceans have absorbed about half the CO2 we have emitted into the atmosphere.
I will also review the Measurement, Reporting and Verification (MRV) of climate treaty verification. A new satellite, the Orbital Carbon Observatory 2, successfully launched on July 2 2014, delivers unprecedented observations of CO2 variations in the atmosphere. I will present a “top-down” approach for estimating carbon dioxide emissions from the atmospheric CO2 variations. Satellite and in-situ CO2 observations together with raw weather observations are assimilated into a global carbon-climate model, so that surface sources and sinks of CO2 can be inferred as required for mass conservation.
This public lecture is sponsored by the Department of Atmospheric Sciences.
