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

 

We are currently seeking a member of staff with an university degree or equivalent in Physics, Remote Sensing, Instrument engineering, or similar with at least 3 years practical experience in the processing of satellite data to generate calibrated Ll datasets in the visible, near- and/or thermal infrared and at least 3-5 years practical experience in Ll calibration/validation

 

Location: Darmstadt, Germany

Start Date: April 2017

Closing date: 8th February 2017

 

TASKS:

 

The tasks of the Contractor to be performed via the Key person will typically include:

  • scientific analysis of the radiometric and spectral calibration of Ll data from  OLCI and SLSTR,
  • analysing results of pre-launch and in-orbit calibration systems and characterisation data , including:
    • solar diffusers, straylight, nonlinearity, SNR, polarisation sensitivity,
    • spacecraft manoeuvres performed during or after commissioning,
  • developing in-depth knowledge of the instruments' operational processing chain,
  • applying calibration monitoring tools to OLCI and SLSTR, including:
    • pseudo-invariant calibration sites,
    • Rayleigh scattering over the sea,
    • lunar calibration,
    • deep convective clouds,
    • inter-calibration against collocated hyperspectral sounder observations,
  • developing specific components of the calibration monitoring tools to handle Sentinel-3 data,
  • analysing results of these tools to assess these sensors' performance,
  • performing comparisons with other instruments, such as AVHRR, VIIRS, MODIS to gain understanding of the performance of OLCI and SLSTR,
  • using the GEOCAL tool developed by ESA to monitor the  geometric performance of OLCI and SLSTR,
  • 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.

 

 

Qualifications and Experience

  • A university degree or equivalent in Physics, Remote Sensing, Instrument engineering, or similar
  • At least 3 years practical experience in the processing of satellite data to generate calibrated Ll datasets in the visible, near- and/or thermal infrared
  • At least 3-5 years practical experience in Ll calibration/validation

 

Essential Skills

 

  • Recognised expertise in the calibration of optical sensors -pre-launch or 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 Key person shall have a knowledge of radiative transfer in the solar and/or infrared spectral ranges and practical experience in applying them for surface and/or atmospheric applications, for example using MODTRAN
  • Proven experience in the use of (i) data analysis tools, such as Matlab/IDL, (ii) scripting languages, such as Perl/Python and (iii) high-level programming, such  as CIC++ in a Linux/Unix 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
  • 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.

 

 

Desirable Skills

 

  • Knowledge and practical experience with the calibration of similar optical sensors, such as MERIS, MODIS, OLCI, (A)ATSR 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.
