“…The method for the optical calibration of the SIS'22 is based on the calibration described on [11] and according to from [12] to [18]. This calibration model assumes that the light wavelength, the temperature, and the relative position of the radiative source can be considered as independent variables.…”

“…The lateral channels have similar behavior. This function will give us information about the angular response of the optical channels by measuring the photocurrent of each channel when the irradiance and the temperature are fixed and only the light incidence angle is changing for the zenith and azimuthal coordinates by using a high precision rotating setup [11]. The angular dependence calibration test has been done in INTA facilities on 13 th and 14 th of July of 2018.…”

This work presents the procedure and results of the optical calibration of the SIS'22 Solar_Irradiance_Sensor (SIS'22) of METEO, the meteorological stations for the Exomars 2022 Kazachok lander. The calibration procedure applied for this multichannel radiometer is an update of the ones carried out on the DREAM-SIS for the Schiaparelli [11]lander in ExoMars '16 and RDS (Radiation_and_Dust_Sensor) for the NASA/JPL Perseverance rover [7], both sensors designed and calibrated by INTA. The main innovation introduced since the DREAMS SIS is the inclusion of some corrections in the models to improve the uncertainties and improve the detectivity limit in low light conditions. Some of the changes introduced are also related to the new challenges that this instrument faced compared to the DREAMS SIS, which had an important impact on the calibration of the mean throughput and the angular dependence (ARF): Narrower FoVs, the necessity of a new characterization of the ARF and its "blocking zone", the use of UV channels, some channels were designed to measure diffuse light in spite of direct sun light, improvement of the offset characterization and a new spectral correction in order to reduce uncertainties.

“…RDS has taken the heritage from previous developments not only for its design but also for its calibration process. The method [29] developed for the calibration of the DREAMS-SIS sensor was followed and improved for the RDS discrete photodetectors. In the camera case, the process was divided into two steps.…”

The Radiation and Dust Sensor is one of six sensors of the Mars Environmental Dynamics Analyzer onboard the Perseverance rover from the Mars 2020 NASA mission. Its primary goal is to characterize the airbone dust in the Mars atmosphere, inferring its concentration, shape and optical properties. Thanks to its geometry, the sensor will be capable of studying dust-lifting processes with a high temporal resolution and high spatial coverage. Thanks to its multiwavelength design, it will characterize the solar spectrum from Mars’ surface. The present work describes the sensor design from the scientific and technical requirements, the qualification processes to demonstrate its endurance on Mars’ surface, the calibration activities to demonstrate its performance, and its validation campaign in a representative Mars analog. As a result of this process, we obtained a very compact sensor, fully digital, with a mass below 1 kg and exceptional power consumption and data budget features.

NASA’s Mars 2020 (M2020) rover mission includes a suite of sensors to monitor current environmental conditions near the surface of Mars and to constrain bulk aerosol properties from changes in atmospheric radiation at the surface. The Mars Environmental Dynamics Analyzer (MEDA) consists of a set of meteorological sensors including wind sensor, a barometer, a relative humidity sensor, a set of 5 thermocouples to measure atmospheric temperature at ∼1.5 m and ∼0.5 m above the surface, a set of thermopiles to characterize the thermal IR brightness temperatures of the surface and the lower atmosphere. MEDA adds a radiation and dust sensor to monitor the optical atmospheric properties that can be used to infer bulk aerosol physical properties such as particle size distribution, non-sphericity, and concentration. The MEDA package and its scientific purpose are described in this document as well as how it responded to the calibration tests and how it helps prepare for the human exploration of Mars. A comparison is also presented to previous environmental monitoring payloads landed on Mars on the Viking, Pathfinder, Phoenix, MSL, and InSight spacecraft.
