Abstract

The scientific objectives of the CLimate Absolute Radiance and REfractivity Observatory (CLARREO) new start recommended by the National Research Council Decadal Survey prioritize high accuracy measurements of infrared spectra, tested for systematic error, tied to international measurements standards, and suitable for testing long-term climate forecasts (of 10 years or more). We present the results from a realistic proof-of-concept study for this mission concept and examine the prospects of testing and improving long-term climate forecasts from ensembles of coupled General Circulation Models (GCMs) such as those participating in the Intergovernmental Panel on Climate Change 4th Assessment Report (IPCC-4AR).
