[Met-jobs] GOME-2 Level 1 Calibration & Validation Consultant

From "Simon Davidson" <recruit@hamtec.co.uk>
To <met-jobs@lists.reading.ac.uk>
Date Tue, 29 Mar 2011 14:59:19 +0100

Location: Darmstadt, Germany

Position: Contract

Rate: € TBD per day

Start Date: July 2011

Duration:  2 years plus a one year option

Tasks

This consultancy is primarily to support the calibration and validation of GOME-2 level 1 data products. The main focus of the activity is the calibration and validation of the GOME-2 UV/Visible radiance and polarisation sensitive data, the evaluation of the long-term degradation signatures in GOME-2 data and methods for generation of degradation correction factors, cross-calibration and validation activities both with instruments of a similar class and GOME-2 instruments on Metop-A and Metop-B, and investigation of problems indicated by feedback from level 1 data users.

Associated with this activity is the development of prototype software to support the analysis and supporting documentation such as algorithm specifications, test data descriptions and validation reports. The consultant will be fully integrated in the LEO Support Team within the Meteorological Division but will also be expected to interface with experts across EUMETSAT as required.

The tasks of the Consultant will include:

  • analysis of in-flight calibration performance of the GOME-2 instruments on Metop- A and Metop-B
  • evaluation of the applicability of the on-ground characterisation key data to the inorbit situation of GOME-2 including radiometric and polarisation sensitivity key data including angular dependencies
  • analysis of the long-term degradation signatures on GOME-2, including from all inflight calibration sources, sun and Earthshine data
  • evaluation of methods for generation of degradation factors
  • cross-calibration and validation of level 1 radiance and polarisation data both with instruments of a similar class and GOME-2 instruments on Metop-A and Metop-B
  • development of software for the purposes of analysing the in-flight calibration performance and long-term degradation performance of the GOME-2 instrument
  • investigation of problems indicated by feedback from level 1 users
  • development of software for cross-calibration and validation activities
  • testing and validation the algorithms and analysis procedures developed;
  • provision of support to the Meteorological Operations Division for long-term instrument monitoring and implementation and validation of the any proposed inorbit corrections within the operational processing environment;
  • interfacing with experts across EUMETSAT as needed;
  • collaboration with expert groups and the wider scientific community outside EUMETSAT as appropriate;

The tasks of the Consultant will be carried out mainly at EUMETSAT facilities in Darmstadt, but travel within Europe may be required for certain activities.

Profile

The GOME-2 level 1 Cal/Val consultant shall have the experience and capability to fulfil the assigned tasks with a minimum of supervision and have good inter-personal skills. He/she shall be familiar with satellite instrument characteristics for Earth observation, in particular calibration and validation of moderate spectral resolution data in the UV/Visible part of the spectrum.

He/she shall have the ability to write concise and comprehensive scientific and technical reports.

In addition to having a University degree (or equivalent) in a relevant discipline, the Consultant shall have a minimum of 5 years experience in the field of remote sensing product data analysis including at least 2 years of experience of UV/Visible calibration and validation.

Specifically the consultant shall have experience in:

  • remote sensing data analysis using UV/Visible satellite data;
  • calibration and validation of level 1 satellite data products;
  • use of (vector) radiative transfer models;
  • the EPS missions and instruments;
  • writing concise and comprehensive scientific and technical reports;
  • demonstrated skills in a higher programming language;
  • specification, design and coding of complex product processors;
  • testing and verification of complex data processing systems;

The following areas of expertise would be an advantage:

  • quality control of satellite data and products;
  • operational product processing environments;
  • knowledge of SQL;
  • software build environments and tools (e.g. make, imake, eclipse, insure++);

·       source code control system, (e.g. Subversion or CVS).
