Join Triple G for their final Colloquium of the fall semester when the MSU Geography Graduate Group welcomes Dr. Gretchen Keppel-Aleks. Dr. Keppel-Aleks is an Associate Professor in the Department of Climate and Space Sciences and Engineering in the College of Engineering at the University of Michigan. This event takes place on Friday, November 17, 2023, at 3:00 PM, in GEO Rm. 126. 

ABSTRACT

Atmospheric CO2 provides a global constraint on carbon exchanges between the atmosphere and oceans or terrestrial ecosystems. The concentration of CO2 in the atmosphere varies on diurnal, seasonal, interannual, and decadal scales, and these temporal scales of variability reflect the impact of different processes occurring over a range of spatial scales, from local to hemispheric. Here, I will describe research to leverage atmospheric CO2 observations together with remote sensing observations of terrestrial ecosystems, to develop estimates of carbon exchange. Such estimates can be used to understand the mechanisms that control the climate sensitivity of carbon exchange and can be used to evaluate predictive climate models.
