Vacancy: KNMI 2015-20 We are seeking a PhD-student to improve and evaluate multi-decadal satellite measurements of formaldehyde (HCHO) and nitrogen dioxide (NO2) in order to test their use as Essential Climate Variables (ECVs). The PhD-project should lead to an improved understanding of the use and fitness for purpose of tropospheric NO2 and HCHO columns retrieved from the GOME, SCIAMACHY, OMI, and GOME-2 sensors. The successful candidate will: • Test and improve the use of land cover information for satellite retrieval algorithms of NO2 and HCHO • Investigate the overall quality of satellite retrieval algorithms by producing (theoretical) traceable algorithm errors • Comparison of NO2 and HCHO long-term data sets with independent reference data • Interpret and evaluate the satellite measurements against TM5 chemistry transport model simulations of tropospheric composition • Document the fitness for purpose of NO2 and HCHO data products for applications such as emission estimates, model evaluation, and trend analysis • Evaluate coherence of the NO2 and HCHO products with GCOS requirements and user requirement The research will be done in the framework of the EU project QA4ECV (www.qa4ecv.eu<http://www.qa4ecv.eu>) and within the OMI project at KNMI (www.knmi.nl/omi<http://www.knmi.nl/omi>). The Ph.D Student will be based at KNMI (4 days per week), and be registered at Wageningen University (1 day per week), working under the supervision of Dr. Folkert Boersma. We are searching for an excellent candidate with an M.Sc in physics, atmospheric sciences, computational sciences or a closely related discipline. Proven research experience is a strong asset. Experience with scientific programming is desirable. Candidates with good communication skills are preferred. More information can be obtained from dr. Folkert Boersma (+31 30 2206 618 / +31 317485524 ).The position is open until 12 June, and applicants can apply directly here: http://www.werkenvoornederland.nl/vacatures/detail/satellite-scientist-for-no2-and-hcho-satellite-data-phd-student Dr. K.F.
