Simulating observations of solar irradiance

Rising concentrations of carbon dioxide and other greenhouse gases in the atmosphere change how much solar radiation is reflected back into space. A proposed NASA mission, Climate Absolute Radiance and Refractivity Observatory (CLARREO), would make benchmark measurements of shortwave reflectance and longwave radiance spectra and of atmospheric refractivity to help researchers understand the changing solar reflectance and its effects on climate. To help mission planners and to determine the utility of solar reflectance data from CLARREO for understanding climate forcings and feedbacks, Feldman et al. (2011) introduce an observational system simulation experiment that calculates the signals of future climate forcings and feedbacks in top-of-atmosphere reflectance spectra. The simulation experiment allows mission planners to simulate CLARREO instrument measurements. They found that expected forcings from increases in anthropogenic emissions would be detectable and the proposed mission should help scientists understand climate forcings and feedbacks.
