“…The emissivity of the cavity (15°C that corresponds to a wavelength of 10 lm) can also influence the TSI measurements. The emissivity of the SOVAP cavity is close to 0.94 and can vary up to 1.5% (Dury et al 2007). C 3 correction that depends on the emissivity takes into account the contribution of the internal thermal emission of the active shutter and its variation during the mission (less than 0.05 W m À2 ).…”

“…One of the RMIB radiometers, VIRGO-DIARAD (Dewitte et al 2004), acquired TSI measurements as part of the VIRGO experiment (Fröhlich et al 1995(Fröhlich et al , 1997 onboard SoHO from 1996 until the present, which represents one of the longest TSI-measurement time series. As a reminder, the DIARAD radiometer is part of VIRGO together with two PMO6V-type radiometers as discussed in Section 1.…”

“…The SOVAP cavity is covered with diffuse black paint (Nextel black velvet). Measurements of the reflectance and ageing characteristics (0.32-14.3 lm wavelength range) of common black coatings were performed by Dury et al (2007). They highlight that the diffuse reflectance remained flat and below 4% for wavelengths between 0.32 and 2.5 lm (solar absorptance is close to 0.96).…”

“…This effect would change the SOVAP TSI measurements by a maximum of 0.5 W m À2 over time. Dury et al (2007) shows that the coating is sensitive to thermal ageing effects (thermal cycling). Physical inspection revealed that the surface of the coating had become cracked after thermal ageing.…”

From the SOlar VAriability PICARD (SOVAP) space-based radiometer, we obtained a new time series of the total solar irradiance (TSI) during Solar Cycle 24. Based on SOVAP data, we obtained that the TSI input at the top of the Earth's atmosphere at a distance of one astronomical unit from the Sun is 1361.8 ± 2.4 W m À2 (1r) representative of the 2008 solar minimum period. From 2010 to 2014, the amplitude of the changes has been of the order of ± 0.1%, corresponding to a range of about 2.7 W m À2 . To determine the TSI from SOVAP, we present here an improved instrument equation. A parameter was integrated from a theoretical analysis that highlighted the thermo-electrical non-equivalence of the radiometric cavity. From this approach, we obtained values that are lower than those previously provided with the same type of instrument. The results in this paper supersede the previous SOVAP analysis and provide the best SOVAP-based TSI-value estimate and its temporal variation.

“…The stray light protector was built of aluminium which was sandblasted, anodized, and painted with NEXTEL velvet black paint. According to Dury et al (2007), the regular and diffuse single scattering reflectance of this coating is typically less than 5 % in the whole spectral range of both spectrometers. Simulations showed that these baffles attenuate incident light that originates from angles more than 15 • outside the FOV by at least 2-3 orders of magnitude.…”

Abstract. The new spectrometer of the Munich Aerosol Cloud Scanner (specMACS) is a multipurpose hyperspectral cloud and sky imager designated, but is not limited to investigations of cloud-aerosol interactions in Earth's atmosphere. With its high spectral and spatial resolution, the instrument is designed to measure solar radiation in the visible and shortwave infrared region that is reflected from, or transmitted through clouds and aerosol layers. It is based on two hyperspectral cameras that measure in the solar spectral range between 400 and 2500 nm with a spectral bandwidth between 2.5 and 12.0 nm. The instrument was operated in ground-based campaigns as well as aboard the German High Altitude LOng Range (HALO) research aircraft, e.g., during the ACRIDICON-CHUVA campaign in Brazil during summer 2014.This paper describes the specMACS instrument hardware and software design and characterizes the instrument performance. During the laboratory characterization of the instrument, the radiometric response as well as the spatial and spectral resolution was assessed. Since the instrument is primarily intended for retrievals of atmospheric quantities by inversion of radiative models using measured radiances, a focus is placed on the determination of its radiometric response. Radiometric characterization was possible for both spectrometers, with an absolute accuracy of 3 % at their respective central wavelength regions. First measurements are presented which demonstrate the wide applicability of the instrument. They show that key demands are met regarding the radiometric and spectral accuracy which is required for the intended remote sensing techniques.
