1. TSIS-1 Reference Solar.

The new solar irradiance reference spectrum is representative of solar minimum conditions between solar cycles 24 and 25. The Total and Spectral Solar Irradiance Sensor-1 (TSIS-1) Hybrid Solar Reference Spectrum (HSRS) is developed by applying a modified spectral ratio method to normalize very high spectral resolution solar line data to the absolute irradiance scale of the TSIS-1 Spectral Irradiance Monitor (SIM) and the CubeSat Compact SIM (CSIM). The high spectral resolution solar line data are the Air Force Geophysical Laboratory ultraviolet solar irradiance balloon observations, the ground-based Quality Assurance of Spectral Ultraviolet Measurements In Europe Fourier transform spectrometer solar irradiance observations, the Kitt Peak National Observatory solar transmittance atlas, and the semi-empirical Solar Pseudo-Transmittance Spectrum atlas. The TSIS-1 HSRS spans 202–2730 nm at 0.01 to ∼0.001 nm spectral resolution with uncertainties of 0.3% between 460 and 2365 nm and 1.3% at wavelengths outside that range.

2. 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.
