GSICS Reference Solar Spectrum

GSICS/CEOS Reference Solar Spectrum Datasets

1. Whole Heliosphere Interval spectrum is an observationally-based spectrum covering 0.1 nm to 2400 nm at 0.1-nm spacing (although that’s smaller than the instrument resolution in some spectral regions) for a time representing solar minimum as based on observations during the 10-16 April 2008 period from multiple instruments. This is thought to supersede Thullier's traditional ATLAS spectrum for accuracy.

2. SAO2010 spectrum. Observationally based using a combination of several ground-, balloon-, and space-based instruments and covers the spectral region from 200 to 1001 nm with 0.04-nm resolution, thanks to the KPNO FTS. Accuracy is about 5%.
