Comparison of Model Estimated and Measured Direct-Normal Solar Irradiance
Direct-normal solar irradiance (DNSI), the total energy in the solar spectrum incident in unit time on a unit area at the earth's surface perpendicular to the direction to the Sun, depends only on atmospheric extinction of solar energy without regard to the details of the extinction whether absorption or scattering. Here we report a set of closure experiments performed in north-central Oklahoma...
متن کاملSensitivity Analysis of Aerosol Parameter Estimations with Measured Solar Direct and Diffuse Irradiance
Sensitivity analysis of aerosol parameter (refractive index which consists of real and imaginary parts, size distribution which is represented by Junge parameter) estimations with measured solar direct and diffuse irradiance is made. Through experiments with the measured solar direct and diffuse irradiance, it is found that the results from the sensitivity analysis is valid and adequate. Keywor...

متن کاملConfronting a solar irradiance reconstruction with solar and stellar data
Context. A recent paper by Shapiro and colleagues (2011, A&A, 529, A67) reconstructs spectral and total irradiance variations of the Sun during the holocene. Aims. In this note, we comment on why their methodology leads to large (0.5%) variations in the solar TSI on century-long time scales, in stark contrast to other reconstructions which have <∼0.1% variations. Methods. We examine the amplitu...
متن کاملDependence of global temperatures on atmospheric CO2 and solar irradiance.
Changes in global average temperatures and of the seasonal cycle are strongly coupled to the concentration of atmospheric CO2. I estimate transfer functions from changes in atmospheric CO2 and from changes in solar irradiance to hemispheric temperatures that have been corrected for the effects of precession. They show that changes from CO2 over the last century are about three times larger than...
