Data on total and spectral solar irradiance
Applied Optics, 1983This paper presents a brief survey of the data available on solar constant and extraterrestrial solar spectral irradiance. The spectral distribution of solar radiation at ground surface, computed from extraterrestrial solar spectral irradiance for several air mass values and for four levels of atmospheric pollution, is also presented.

, 2016 The importance of the reliable solar spectral irradiance (SSI) data for solar and climate physics is now well acknowledged. In particular, the irradiance time series are necessary for most of the current studies concerning climate evolution. However, space instruments are vulnerable to the degradation due to the environment while ground based ...

Solar spectral irradiance and total solar irradiance at a solar minimum
Geomagnetism and Aeronomy, 2014Results are presented for a wavelet analysis of solar spectral irradiance (SSI) in the ultraviolet to infrared range and total solar irradiance (TSI). The study is based on data collected by the Solar Radiation and Climate Experiment (SORCE) satellite from March 10, 2007 to January 23, 2010. Cross-wavelet analysis finds relationships of varying degrees

SOLAR SPECTRAL IRRADIANCE IN THE VISIBLE AND INFRARED REGIONS
Photochemistry and Photobiology, 1988Abstract— The analytical formulas previously developed for estimating the spectral irradiance reaching the ground in the ultraviolet are extended into the visible and infrared(350–3000 nm). This approach has two distinct features: (1) all physical inputs for calculating the direct irradiance are given in analytical form, and (2) the diffuse spectral ...

Solar Spectral Irradiance Monitor (SIM)
Metrologia, 2000The Spectral Irradiance Monitor (SIM) will measure the solar spectral irradiance between 0.2 µm to 2.0 µm to a relative standard uncertainty of 3 × 10−4 (1 s) and with a noise level of

Remeasuring the extraterrestrial solar spectral irradiance
SPIE Proceedings, 2003We will measure the solar spectral irradiance by deploying a CCD-array solar spectrograph to a high altitude favorable site, as part of a self-contained autonomous system with a calibration system using a monochromator and absolute photodiode "trap detectors." Data will be reduced using Langley extrapolation (and in the stronger absorption bands ...

Solar EUV and UV spectral irradiances and solar indices
Journal of Atmospheric and Solar-Terrestrial Physics, 2005Abstract Several experiments have measured solar EUV/UV flux in the last 10–15 years including SUSIM UARS, SOHO CELIAS SEM, and SOHO EIT and have generated multi-year spectral irradiance time series. Empirical models of these important sources of radiant energy are often based on solar activity proxies, most often, the solar 10.7 cm radio flux ...

Solar radiometry: Spectral irradiance measurements
Advances in Space Research, 1982The present measurement accuracy of the solar spectral irradiance is insufficient to derive the real long-term solar spectral irradiance variability at all wavelengths. Possible error sources are discussed. A series of new second generation solar irradiance photometers are now under construction which should considerably improve these measurements.

Total and spectral solar irradiance measured at ground surface
Applied Optics, 1982This paper presents the results of a series of total and spectral solar irradiance measurements made at ground surface (Table Mountain Facility, Calif., altitude 2.18 km). The spectral irradiance data are presented for the 0.3-3.0-microm spectral region for air mass 1.5.
