Executive Summary

We propose to discover and correct biases in satellite microwave records of atmospheric temperatures and to assess their influence on current simulations of the atmospheric warming response to increasing greenhouse gas concentrations. If successful, these improvements in our ability to accurately simulate future climate change will increase our understanding of Earth’s climate sensitivity and better inform energy policy.
