Mission-Long Spectral Irradiance Blue channel data of the SOHO/VIRGO/SPM

The mission-long spectral irradiance blue channel data of the SOHO/VIRGO/SPM. The Sunphotometer (SPM) is a part of the Variability of Solar Irradiance and Gravity Oscillations (VIRGO) aboard the Solar and Heliospheric Observatory (SOHO).

The SPM instrument is composed of a triple sunphotometer with three interference filters (402, 500, and 862 nm) and a silicon photodiode detector measuring the spectral irradiance in the solar continuum.

本数据集为太阳和日球层天文台（Solar and Heliospheric Observatory, SOHO）搭载的太阳辐照度与重力振荡变异性（Variability of Solar Irradiance and Gravity Oscillations, VIRGO）载荷中的太阳光度计（Sunphotometer, SPM）的全任务周期光谱辐照度蓝通道数据。其中，太阳光度计（SPM）是该载荷的组成部分。SPM仪器由一台搭载402 nm、500 nm与862 nm干涉滤光片的三重太阳光度计，以及用于测量太阳连续谱光谱辐照度的硅光电二极管探测器构成。
