[Met-jobs] PhD-student - Improving and interpreting NO2 and HCHO satellite data at KNMI and Wageningen University

From "Boersma, Folkert (KNMI)" <folkert.boersma@knmi.nl>

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:
