Since 1979, Italian ACS has been a Software System Integrator. As a Payload Data Ground Segment specialist, ACS develops componentssubsystemsground stations for satellite data acquisition, processing and dissemination. The company is active in geospatial multisource applications development for planning and management of environmental risks infrastructures and realtime handling of large data streams. ACS offer to their customers the complete range of services from the collection of user requirements to operational activities support. Our German subsidiary ACSD provides consultancy service at EUMETSAT Darmstadt. Selected candidate will sign a permanent fulltime contract and work at EUM premises. Besides an opportunity to work in international environment, ACS can offer a competitive salary, attractive benefits package tailored to specific needs, training and career growth within ACS group, support for relocation to Darmstadt. For our activities in Germany, we are looking for a person to provide Optical Sensor Calibration Expert support. TASKS 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 ofOLCI 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. Mandatory A university degree or equivalent in Physics, Remote Sensing, Instrument engineering, or similar Fluency in English At least 5 year experience in the processing of satellite data to generate calibrated Ll datasets in the visible, near andor thermal infrared. At least 5 year experience in L 1 calibrationvalidation. Recognised expertise in the calibration of optical sensors both prelaunch and in orbit. A good working knowledge of statistical techniques and understanding of the concepts of calibration and traceability. 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 EUMETSA T and with Industry and ESA EU national or valid work permit for Germany CV in Europass format 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.
