“…In situ ocean measurements from the Argo network [6] have reached the state-of-the-art accuracy of ±0.3 W/m 2 on the EEI [7]. However, since these measurements are averaged over at least one decade, they contain large sampling uncertainties at shorter timescales and are therefore not suited for short-term climate monitoring [8]. Next to the in situ ocean measurements, broadband satellite observations of the ERB are another well-established scientific method to evaluate EEI values [9].…”

“…During the Earth Radiation Budget Experiment (ERBE) mission [13], the low-resolution ERB measurements obtained using WFOV radiometers were compared with the higher resolution measurements from the scanning radiometers. The latter provided measurements with a better spatial resolution and avoided the thermal offset problems of WFOV radiometers [8]. Hence the CERES program continued with scanning radiometers [11,12].…”

“…However, no measurement technique has yet reached the absolute accuracy of 1 W/m 2 required to make significant measurements of the EEI. Alternative observation methods to determine the EEI have been summarised by Wong et al [8], but have not demonstrated sufficient accuracy either [4]. For all these reasons, and considering advances in instrument technology and the availability of small satellite platforms [8], the determination of the EEI using broadband non-scanning WFOV instruments has recently received a renewed interest.…”

Design and Analysis of a Next-Generation Wide Field-of-View Earth Radiation Budget Radiometer

Climate on Earth is determined by the Earth Radiation Budget (ERB), which quantifies the incoming and outgoing radiative energy fluxes. The ERB can be monitored by non-scanning wide field-of-view radiometers, or by scanning narrow field-of-view radiometers. We propose an enhanced design for the wide field-of-view radiometer, with as key features the use of a near-spherical cavity to obtain a uniform angular sensitivity and the integration of the shuttered electrical substitution principle, eliminating long term drifts of the radiometer and improving its time response. The target absolute accuracy is 1 W/m 2 and the target stability is 0.1 W/m 2 per decade for the measurement of the total outgoing Earth’s radiation. In order to increase the spatial resolution and to separate the total outgoing radiation into reflected Solar and emitted thermal radiation, we propose the joint use of the radiometer with wide field-of-view Shortwave (400–900 nm) and Longwave (8–14 μm) cameras. This paper presents the concept and design of the novel wide field-of-view radiometer, including simulations and analyses of its expected performance. We focus on mechanical design and the measurement characteristics based on optical and thermal analyses. In combination with the cameras, we obtain an estimated accuracy of 0.44 W/m 2 .

“…In the case of a satellite constellation, the instrumental calibration (pre-flight calibration with the same primary standard source, in-flight calibration to monitor aging with the same process) aspects will have to be studied in detail to guarantee accuracy and precision for each satellite. Indeed, the determination of top of atmosphere global net radiation budget using broadband non-scanner instruments remains complex due to outstanding calibration challenges [46]. .…”

The UltraViolet and infrared Sensors at high Quantum efficiency onboard a small SATellite (UVSQ-SAT) mission aims to demonstrate pioneering technologies for broadband measurement of the Earth’s radiation budget (ERB) and solar spectral irradiance (SSI) in the Herzberg continuum (200–242 nm) using high quantum efficiency ultraviolet and infrared sensors. This research and innovation mission has been initiated by the University of Versailles Saint-Quentin-en-Yvelines (UVSQ) with the support of the International Satellite Program in Research and Education (INSPIRE). The motivation of the UVSQ-SAT mission is to experiment miniaturized remote sensing sensors that could be used in the multi-point observation of Essential Climate Variables (ECV) by a small satellite constellation. UVSQ-SAT represents the first step in this ambitious satellite constellation project which is currently under development under the responsibility of the Laboratory Atmospheres, Environments, Space Observations (LATMOS), with the UVSQ-SAT CubeSat launch planned for 2020/2021. The UVSQ-SAT scientific payload consists of twelve miniaturized thermopile-based radiation sensors for monitoring incoming solar radiation and outgoing terrestrial radiation, four photodiodes that benefit from the intrinsic advantages of Ga 2 O 3 alloy-based sensors made by pulsed laser deposition for measuring solar UV spectral irradiance, and a new three-axis accelerometer/gyroscope/compass for satellite attitude estimation. We present here the scientific objectives of the UVSQ-SAT mission along the concepts and properties of the CubeSat platform and its payload. We also present the results of a numerical simulation study on the spatial reconstruction of the Earth’s radiation budget, on a geographical grid of 1 ° × 1 ° degree latitude-longitude, that could be achieved with UVSQ-SAT for different observation periods.
