The APEX project (http://www.apex-esa.org) is offering a PhD position
within the Remote Sensing Laboratories (http://www.geo.unizh.ch/rsl/)
at the Dept. of Geography (http://www.geo.unizh.ch/) of the University
of Zurich (http://www.unizh.ch). The position offered is for those who
would like to become active in instrument calibration and processing
of imaging spectrometry data with particular interest in Earth remote
sensing, geoinformatics, spectroscopy and environmental issues.

APEX is a joint Swiss/Belgian and ESA (http://www.esa.int) funded
project and has a strong international component. APEX is an airborne
imaging spectrometer and the experiments includes the development of
hard- and software, the calibration, and the operation of the
instrument. The hardware component of APEX is being developed by a
Swiss/Belgian/French/German consortium, whereas the software (the
'Processing and Archiving Facility' (PAF)) is fully developed at
RSL. The operational phase will be under the guidance of VITO in
Belgium.

The core APEX team at RSL is composed of 4 researchers, whereas one
position of this team is now being offered in this announcement. The
PAF is the operational Level 0 to 1 processor. It converts the raw
instrument output to radiance at sensor in physical units [W/nm/m2/sr]
using the calibration parameters measured in the laboratory at DLR,
Oberpfaffenhofen. A first functional version has been tested and
released in February 2005. Future extensions shall add modules for the
analysis of the laboratory calibration measurements, the atmospheric
correction, and standard surface reflectance products.

The successful candidate shall ensure and document the proper
instrument calibration during the first years of operation, 2007/08.
This is the vital first step of all subsequent data analyses and
applications of APEX. It will be carried out in close cooperation with
our colleagues at DLR, HTS and Vito.

It involves the following task:

1) Develop a PAF module for the calculation of the calibration
parameters from the laboratory calibration measurements.

2) Update the PAF to maintain compatibility with the actual
instrument, which is currently being built.

3) Analyze the acceptance laboratory and flight campaigns.

4) Monitor instrument performance during subsequent operational
flights and laboratory measurements.

5) Participation in various project activities such as review of
industry milestone documentation, planning of flight campaigns,
development of novel APEX products (land, water, and atmospheric
parameters), etc.

6) Publish your findings in internationally accepted journals and
literature.

The applicant will be expected to have experience in either
spectrometer calibration or remote sensing. Programming skills,
e.g. C(++), Fortran, IDL, are essential. A background in physics or
engineering would be an advantage.

Requirements: At the time of job start, the candidate must have a
Masters Degree in science of an accepted University to qualify for
this position.

Salary: Swiss University standards, 50-75% employment.

Duration: Commencing autumn 2005 to autumn 2008 (funding
secured), extension likely, subject to individual skills.

Language: Fluency in English and/or German is a prerequisite,
knowledge of other languages (French, Dutch) an asset.

Location: Spectroscopy Lab (http://www.geo.unizh.ch/rsl/spectrolab/),
Department of Geography, University of Zurich, Switzerland.

Employment: The University of Zurich is an equal opportunity
employer. All non-resident aliens are subject to State rules of
eligibility to work. Support on obtaining work permits is available.

Please send your application by e-mail (plain text (no HTML mail) or
PDF) to Jens Nieke (mailto:nieke@geo.unizh.ch). Applications are
accepted until position is filled.

The application shall consist of:
1. Curriculum vitae.
2. Bibliography (numbered).
3. Description of the candidate's research achievements and
experience.
4. The names of one referee
(English, German, French, Dutch speaking, they will be
contacted only if candidate is selected for short list).

Zurich is the largest city in Switzerland and is located adjacent to
the Alps with easy access to outdoor recreation opportunities.
International connections are available through the nearby Zurich
airport and the multi-language ability of the Swiss offer a variety
of cultural events for all interests. Zurich hosts two Universities
(the University of Zurich (http://www.unizh.ch) and the Swiss Federal
Institute of Technology (http://www.ethz.ch)), totaling over 30'000
students and faculty.
