Hello, Please find in attachment an advertisement for a Postdoctoral position in Paris, France. Thank you very much. Best regards, Irène Xueref-Remy Postdoctoral position Analysis of the variability of atmospheric CO2 and CO:CO2 emission ratios for quantification of emissions from traffic in the Paris megacity. Duration : 8 months Starting date : February 1st, 2014 (expected) Location : Laboratoire des Sciences du Climat et de l’Environnement LSCE CEA-CNRS-UVSQ Orme des Merisiers 91191 Gif-sur-Yvette CEDEX – France Responsible : Irène Xueref-Remy (tel : +33 1 69 08 98 01 / firstname.lastname@example.org) et Philippe Ciais (email@example.com ) Name of the project : CarboCount-City (KIC CLIMATE). The Carbocount City project aims to develop a service for cities to quantify, understand their greenhouse gas emissions in order to help them meet their emission reduction target. The elements of this service are developed by LSCE and partner corporate partners. Skills requirements : The candidate should have a phD in atmospheric Physics. Skills in data analysis using statistical tools using standard software packages (e.g. R, Matlab, IDL) are required. Due to the short length of the position, experience with atmospheric data analysis is an advantage. Position summary: More than 70% of global CO2 emissions come from urbanized areas, especially from megacities. Paris, the second largest megacity in Europe emits about 50 MtCO2 per year, mainly from car traffic and residential / commercial buildings. To date, knowledge from emissions is from inventories based on energy use statistics that are not independently evaluated using measurements, and not slidfrequently updated. During the combustion process of gasoline, CO2 is co-emitted with other species such as CO (and NOx) in proportion that are specific of each fossil fuel type and combustion type (e.g. different traffic conditions and car engines). The analysis of CO:CO2 ratios in the urban atmosphere can help understand the relative role of traffic based emissions among the total CO2 emitted. The candidate will use atmospheric CO2 and CO measurements to characterize the variability of atmospheric CO2 and CO:CO2 emission ratios from the traffic sector. The data will come from intensive field campaigns of atmospheric CO2 and CO measurements using a Cavity Ring Down Spectrometer into a mobile platform. Over a year and starting in November 2014, a total of 6 campaigns of 1500km/10 days each will be carried out in the Paris area, using on the same transect to facilitate comparison between the campaigns and available inventories and atmospheric model results. These data will be acquired and made available to the candidate. We seek for a young scientist who will process, calibrate and analyze the data for characterizing the diurnal, weekdays/weekend and seasonal variability of traffic-emitted CO2 and CO:CO2 emissions. The candidate will interact with the people in charge of gathering the field data and participate to some of the mobile field campaigns. The results from this work should be a slid scientific analysis in the prospect of the development of atmospheric tools to help cities authorities measure emissions from traffic. The candidate will interact with corporate partners, the Climate KIC people and stakeholders, as well as with atmospheric inversion modelers working in the Carbocount-City project to infer city-scale emissions over the Paris area, in view of the forthcoming COP21 event in 2015. Salary: The salary will be commensurate with experience, on the order of 33000 euros net per year, including full health care and retirement pension benefits. Applications: Applications should include a CV and a cover letter, and if possible the names of two reference persons, and sent to firstname.lastname@example.org, email@example.com and firstname.lastname@example.org.
