Vitrociset Belgium, a Vitrociset Group company, can claim almost 30 years of experience in the field of space operations engineering activities, starting in 1982 with the European Space Agency. Today Vitrociset Belgium is the Corporate Groups center of gravity for the Space activities in central Europe. With the headquarter located in Belgium and permanent offices presence close to ESAs centers ESOC D, ESTEC NL and ESAC SP, the company offers you major opportunities at its many sites abroad, an international environment and assignment to prestigious clients ESA, CNES, EUMETSAT, ASTRIUM. Summary of the role The job category of the position is for a Senior Scientist Remote Sensing Expert Optical. The key person support the Sentinel3 Optical Sensor Calibration, which will support the EUMETSAT Copernicus Sentinel3 Operations Team within the EUMETSAT Operations and Services to Users Department OPS with the support of the EUMETSAT Technical and Scientific Support Department TSS. The focus of this Sentinel3 Optical Sensor Calibration Expert consultancy is to support the calibration of the Ocean and Land Colour Imager OLCI and Sea and Land Surface Temperature Radiometer SLSTR instruments on the Sentinel3 mission, which EUMETSAT operates on behalf of the European Commission. Hence, the focus will be to provide an indepth understanding of the instruments calibration and characterization in orbit. The calibration data and instrument performance will be analyzed using existing tools and by developing inhouse tools for instrument calibration as well as vicarious and inter calibration to adjust and monitor the operational calibration systems. The Key person shall support the Calibration Team of INRC competence area, in close collaboration with the Ocean Colour and Surface Temperature Radiometry teams in the Marine Applications competence area, whose activities the consultant shall primarily support. Key Responsibilities scientific analysis of the radiometric and spectral calibration of LI data from OLCI and SLSTR, analyzing results of prelaunch and inorbit calibration systems and characterization data , including solar diffusers, straylight, nonlinearity, SNR, polarisation sensitivity, spacecraft manoeuvres performed during or after commissioning, developing indepth knowledge of the instruments operational processing chain, applying the calibration monitoring tools to OLCI and SLSTR, which will include a combination of pseudoinvariant calibration sites, Rayleigh scattering over the sea, lunar calibration, deep convective clouds, intercalibration against collocated hyperspectral sounder observations, developing specific components of the calibration monitoring tools to handle Sentinel3 data, analyzing results of these tools to provide information on these sensors performance, performing comparisons with other instruments, such as AVHRR, VIIRS, MODIS to gain understanding of the performance of OLCI and SLSTR, using GEOCAL tool developed by ESA to monitor geometric performance, providing recommendations to implement changes to the operational procedures and processing chains to improve the instruments calibration, working with the team responsible for generating L2 products for these instruments to assess and improve the instruments calibration, writing and reviewing documentation describing the instruments calibration and aspects of their L1 processing. Please send your CV to Ms Roxana Sasu at r.sasuvitrocisetbelgium.com Requirements A university degree or equivalent in Physics, Remote Sensing, Instrument engineering, or similar At least 5 years of experience in the processing of satellite data to generate calibrated Ll datasets in the visible, near andor thermal infrared. At least 5 years of experience in L 1 calibrationvalidation. Recognized expertise in the calibration of optical sensors both prelaunch and on orbit. The key person shall be able to demonstrate a good working knowledge of statistical techniques and understanding of the concepts of calibration and traceability. The Consultant shall have a good knowledge of radiative transfer in the solar andor infrared spectral ranges and experience in applying them for surface andor atmospheric applications. Proven experience in the use of data analysis tools, such as MatlablDL, scripting languages, such as PerlPython and highlevel programming, such as CCFORTRAN on a LinuxUnix environment, and an aptitude to learn further programming languages as required. Experience in the implementation of calibration algorithms. Very good communication skills both verbal and written are an important aspect of this role both between teams within EUMETSAT and with Industry and ESA And the following abilities To work effectively in a small team To work autonomously without close supervision To work to tight deadlines under changing conditions To analyse complex problems, distinguishing between critical and less critical information, and to synthesise and clearly present the results of such analyses. Additionally, the following experience would be considered advantageous Knowledge and practical experience with the calibration of similar optical sensors, such as MERIS, MODIS, OLCI, AATSR or AVHRR. Experience of working in an operational satellite environment. Experience of image analysis. Experience with a range of different data formats used in satellite remote sensing. Experience with Software build environments and version control tools. Fluency in English is mandatory. Please be advised that by submitting your CV or other content to us, you agree to the administration, processing and storage of any personal data for the purposes of recruitment processes. The agreement covers the processing of personal data by Vitrociset Belgium even after finishing the recruitment process to submit further proposals for employment and may be revoked at any time.
