What connects the ever growing Serco workforce is a passion for delivering great service To keep ahead we have to constantly evolve and enhance the way we deliver our services and everyone in Serco has a role to play here. Serco provide the right environment to encourage ideas and a comprehensive Best Practice support network that enables them to put their ideas into action. If you share our values then join with over 100,000 colleagues globally who are equally as passionate about delivering great service as you. For our activities in EUMETSAT, we are currently looking for an Optical Sensor Calibration Expert. Package description Full details on application. Relocation assistance provided if applicable. Main responsibilities The focus of this Sentinel3 Optical Sensor Calibration Expert 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 characterisation in orbit. The calibration data and instrument performance will be analysed using existing tools and by developing in house tools for instrument calibration as well as vicarious and intercalibration 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. The tasks of the Key person will typically include scientific analysis of the radiometric and spectral calibration of Ll data from OLCI and SLSTR analysing results of prelaunch and inorbit calibration systems and characterisation 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, analysing results of these tools to provide information on these sensors performance, performing comparisons with other instruments, such as A VHRR, 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 Ll processing. Ideal candidate Essentials The key person shall have a university degree or equivalent in Physics, Remote Sensing, Instrument engineering or similar and the following specific technical skills and experience At least 5 years experience in the processing of satellite data to generate calibrated Ll datasets in the visible, near andor thermal infrared. At least 5 years experience in L1 calibrationvalidation. Recognised expertise in the calibration of optical sensors both prelaunch and on orbit. The Consultant 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 MatlabIDL, 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. Additionally, the key person should be able 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. Desirables 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 A VHRR. 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.
