We present a new solar irradiance reference spectrum 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.
我们展示了一种新的太阳辐照度参考光谱，它代表了太阳活动周期24和25之间太阳活动极小期的情况。总太阳辐照度和光谱太阳辐照度传感器-1（TSIS-1）混合太阳参考光谱（HSRS）是通过应用一种改进的光谱比方法开发的，该方法将非常高光谱分辨率的太阳谱线数据归一化到TSIS-1光谱辐照度监测仪（SIM）和立方星紧凑型SIM（CSIM）的绝对辐照度尺度。高光谱分辨率的太阳谱线数据包括空军地球物理实验室的紫外太阳辐照度气球观测数据、欧洲光谱紫外测量质量保证地面傅里叶变换光谱仪太阳辐照度观测数据、基特峰国家天文台太阳透过率图集以及半经验太阳伪透过率光谱图集。TSIS-1 HSRS的光谱范围为202 - 2730纳米，光谱分辨率为0.01至约0.001纳米，在460至2365纳米之间的不确定度为0.3%，在该范围之外的波长处不确定度为1.3%。
