2011 – 2014
Fitsum was supervised by Ashish, Sivakumar and Raj, and worked on characterising uncertainty in GCM simulations, coming up with a metric that gave a standard error associated with GCM precip and temperature simulations that varied in space and time. This metric showed clearly that GCM structural uncertainty was the dominant source of uncertainty, and while this remained more or less unchanged over time, the scenario uncertainty increased as would be expected.
