英文摘要 | The near-infrared solar spectral irradiance (SSI) is of vital importance for understanding the Earth's radiation budget, and in Earth observation applications. Differences between previously published solar spectra (including the commonly used ATLAS3 spectrum) reach up to 10% at the low wavenumber end of the 4,000-10,000cm(-1) (2.5-1 mu m) spectral region. The implications for the atmospheric sciences are significant, since this spectral region contains 25% of the incoming total solar irradiance. This work details an updated analysis of the CAVIAR SSI, featuring additional analysis techniques and an updated uncertainty budget using a Monte Carlo method. We report good consistency with ATLAS3 in the 7,000-10,000 cm(-1) region where there is confidence in these results due to agreement with other spectra, but similar to 7% lower in the 4,000-7,000 cm(-1) region, in general agreement with several other analyses. Plain Language Summary The total energy arriving to Earth from the Sun is well known, but how much of this is visible; ultraviolet or infrared light is also important. This paper presents measurements of the Sun's infrared energy that reaches Earth. This infrared energy heats up the atmosphere as it is absorbed by the surface and by gases such as carbon dioxide and water vapor. Knowing how much of this infrared energy reaches us is important for weather prediction and for simulations of climate change (which depends on the amount of energy arriving at and leaving the atmosphere). Previous measurements of the Sun's infrared energy from both the ground and from satelites show significant disagreement. Our measurements help resolve this disagreement, and will enable more accurate representation of the Sun's infrared energy in weather and climate predictions. |
