[Met-jobs] MTG IRS Scientist

HAMTEC Consulting a provider of quality consultants to the aerospace industry.


We are currently seeking a University educated engineer who shall have at least five year’s experience with the retrieval of geophysical properties from hyperspectral infrared observations


Location: Darmstadt, Germany

Start Date: As soon as Feasible

Closing date: 12 August 2011




The consultant will be integrated into the MTG-IRS science support team within EUMETSAT MET Divisions. This team provides in-house hands-on knowledge of IRS Level 2 processing. It supports the procurement, verification, calibration, and product validation of the operational implementation of the L2PF IRS Level 2 processing. To support procurement, the team will provide specifications, test data, and software tools. The team will formulate their initial specifications in an Algorithm Theoretical Basis Document that describes the physical principles of end-to-end product processing in the L2PF, and then transfer these, developing them in sufficient detail to allow a software contractor to implement them, into a Product Generation Specification (PGS). The team will also provide test data to verify that the contractor has implemented the specification correctly. The team procures input test data (simulated upwelling spectra as recorded by the IRS instrument) through study contracts with external entities. The team generates output test data using several software tools, the most important of these being an existing end-to-end prototype processor. The consultant will support these activities, primarily through further development and maintenance of the prototype processor, preparation of test data, and application of the prototype processor to test data. The current prototype processor is an implementation of a Bayesian methodology to optimally estimate the Earth/Atmospheric state from a combination of a-priori information and hyperspectral infrared satellite observations.


In particular the tasks will include:


  • Support the maintenance of the Algorithm Theoretical Basis Document (ATBD), describing the physical principles of the L2PF IRS Level 2 product processing.
  • Support the generation of the Product Generation Specification (PGS), specifying the processing in sufficient detail to allow a software contractor to implement it.
  • Support the development and maintenance of prototype processor capable of extracting geophysical information from hyper-spectral space-borne observations in line with the functional description documented in the ATBD.
  • Support the development and maintenance of test datasets that can be used to demonstrate the functionality implemented in the prototype processor and to verify the correct implementation of the functionality described in the PGS.
  • Support the generation of static application data for the processing modules embedded in the prototype processor and, later, the operational processor.
  • Create reports and presentations, including internal reports, on aspects of the tasks above;
  • Any other tasks deemed appropriate by the technical officer in support of the overall aim of the tasks above..


Qualifications and Experience

·        A University degree in a relevant discipline

·        Five years experience with the retrieval of geophysical properties from hyperspectral infrared observations


Essential Skills

Desirable Skills


·        Processing of raw Fourier transform spectrometer observations into radiometrically and spectrally calibrated spectra,

·        Statistical methods to derive geophysical parameters from hyper-spectral infrared observations,

·        Rapid algorithm prototyping and test data generation in support of the above,

System software engineering including

·        Configuration Control;
