“Diagnosing the Carbon Cycle from Remote Measurements of the Atmosphere”.
This seminar discusses the response of land and ocean sinks of carbon to weather and climate changes using atmospheric inverse modeling. Sourish Basu, who is an atmospheric modeler at NASA Goddard Space Flight Center, will explore the limitations of traditional in situ-based inverse models and the new insights provided by satellite measurements of greenhouse gases.
About the seminar
Understanding the response of the land and ocean sinks of carbon to changes in weather and climate has been a long standing goal in the geosciences. These sinks can be quantified through atmospheric inverse modeling, which infers surface fluxes from observed gradients of the gases in the atmosphere. Historically, these observations have been in situ, i.e., either the instrument is at the location of the measurement, or the instrument analyzes a gas sample collected elsewhere. In the past 15 years, remote measurements from satellite platforms have become popular as a way of providing measurements in hard-to-access parts of the world. In this talk, Sourish will give a brief description of atmospheric inverse modeling, the lessons we have learned from traditional in situ-based inverse models, their limitations, and the new information provided by satellite measurements of greenhouse gases.
About Sourish Basu
Sourish Basu is an atmospheric modeler at the NASA Goddard Space Flight Center in Maryland, USA. His primarily responsibility is understanding the carbon cycle through atmospheric measurements of CO₂ and CH₄, both in situ and remotely sensed. In addition to these measurements, he also uses isotopic measurements of the tracers to understand processes behind their sources and sinks.
