SRONs mission is to bring about breakthroughs in international space research. Therefore, the institute develops pioneering technology and advanced space instruments, and uses them to pursue fundamental astrophysical, Earth science and exoplanetary research. As national expertise institute SRON gives counsel to the Dutch government and coordinates national contributions to international space missions. SRON stimulates the implementation of space science in our society. Our Earth Science Group has a vacancy for a Postdoc Scientist fm Vacancy number 1401 Project Outline At the Paris climate conference COP 21 in December 2015, 195 countries adopted the first legally binding climate agreement to reduce greenhouse gas emissions, with the aim to limit global warming to well below 2oC by 2100. To support the monitoring of national emission reduction pledges, European scientists are preparing the launch of the Copernicus CO2 monitoring constellation. It will consist of 3 or 4 satellites for highresolution imaging of anthropogenic CO2 emissions. The challenge is to meet the required measurement sensitivity and accuracy, which are highly demanding for longlived greenhouse gases such as CO2. An important factor limiting the accuracy of space borne CO2 measurements is atmospheric scattering of light on aerosol and cirrus cloud particles. Several options are considered to mitigate such errors, including the deployment of a dedicated aerosol sensor on the spacecraft. The aim of this project is to investigate the benefit of this solution, as well as alternatives, using Observing System Simulation Experiments OSSEs. These experiments simulate the impact of scattering induced errors on CO2 emissions that are derived from the measurements using inverse modelling techniques. The OSSEs will address the estimation of anthropogenic CO2 emissions on spatial scales ranging from regional scale of countries to local scale of cities. The assumptions used in the OSSEs will be based on measurements from NASAs Orbiting Carbon Observatory 2, which has been collecting CO2 data since summer 2014. Tasks The successful applicant will design OSSE experiments using TM54DVAR regional scale and WRFCHEM local scale to test the performance of the CO2 monitoring system depending on the approach to mitigate systematic retrieval errors from atmospheric scattering. OCO2 data will be analyzed to ensure that the assumptions that are used in the inversion setup are realistic. The research will be conducted in cooperation with other international partners within two European H2020 projects CHE and SCARBO, requiring active participation at annual assemblies and project telecons and presentation of the achieved progress. As part of the SCARBO project, aircraft campaign will be conducted to investigate the synergy between remotely sensed CO2 and aerosol. The applicant will support the flight planning using model results and will assist in the interpretation of the data. The main outcomes will be published in peer reviewed journals. Requirements For this project we are looking for an ambitious, highly motivated and result driven scientist with a PhD degree in atmospheric physicschemistry, with experience in atmospheric inverse modelling of longlived greenhouse gases. Experience with the use of real observations in situ or satellite measurements is considered a clear asset. Good knowledge of the English language is essential, and the candidate should be capable to work both independently and in a team. Functional competencies Results oriented Analytical Can communicate clearly SRON core competencies Innovative Focused on collaboration Responsibility A global player Flexibility Employment conditions Employment of this fulltime position as a Scientist C at SRONUtrecht is by NWOI The Netherlands Organization for Scientific Research Institutes and will be for a period of 2 years.

Internal Research Fellow PostDoc in modelbased Verification Validation of autonomous systems
2018-05-18 14:25:31| Space-careers.com Jobs RSS
Research Fellow opportunity in the Directorate of Technology, Engineering and Quality. ESA is an equal opportunity employer, committed to achieving diversity within the workforce and creating an inclusive working environment. Applications from women are encouraged. Post Internal Research Fellow PostDoc in modelbased Verification Validation of autonomous systems This post is classified F2 on the Coordinated Organisations salary scale. Location ESTEC, Noordwijk, The Netherlands Description The Software Systems Division covers engineering, verifictaion and validation techniques for space systems, in particular in the functional domain. This includes missioncritical software, software technology for flight as well as ground systems, realtime software embedded in spacecraft systems and payloads, but also ground facilities software, including electrical ground support equipment, test benches, databases and simulation and modelling tools. Future missions will rely on an increased level of autonomy to enable more compplex missions and an increased perfromance. For the design of such missions, increased use is made of modelbased methods and tools, impacting the engineering information manageent along the life cycle of the development. The impact of this evolution on the verifictaion and validation process needs to be fully understood to ensure the required quality of these missions. Interested candidates are highly encouraged to visit ESA website www.esa.int Fields of activitiesresearch Future space exploration missions will require autonomous robotic systems with selfawarenessadaptation capabilities. Achieving acceptable performance and assurance levels for an autonomous robotic system will require substantial verification and validation activities. Coverage of these activities will take place at several levels and at several points in the Vcycle, and will be provided through both experimentation and test benches. Finally and importantly, the verification and validation approach must match the processes increasingly being adopted by space system integrators modelbased system engineering and increasingly virtual engineering, requiring the ability to switch effortlessly between the physical and virtual worlds and to apply consistent test conditions and test results analysis in either case. In this respect the Harwell Robotics and Autonomy Facility HRAF provides a framework for the testing and evaluation of autonomous robotic systems. Initiated a few years ago, its incremental development has focused on the HighLevel Architecture HLA based distributed simulation environment and planetary rover field tests. In support of this development, the research will address the verification and validation coverage for systemlevel testing on the bench as part of modelbased engineering for specifying, developing, testing and evaluating autonomous robotic systems. In particular, a simulationbased validation methodology, including worst case scenarios and reference use cases, will be defined, and the selected blackbox testing methods will be developed and evaluated on the HRAF. The research will involve SysML or equivalent modelling at system level and will consider a planetary rover as the main application. The post will involve collaboration at ESA Directorate level as well as with academic and industrial partners.

Internal Research Fellow PostDoc on FLEX, Sentinel 23 missions
2018-05-15 11:26:47| Space-careers.com Jobs RSS
Research Fellowship Opportunity in the Directorate of Earth Observation Programmes. ESA is an equal opportunity employer, committed to achieving diversity within the workforce and creating an inclusive working environment. Applications from women are encouraged. Post Internal Research Fellow PostDoc on FLEX, Sentinel 23 missions This post is classified F2. Location ESTEC, Noordwijk, The Netherlands Our team and mission The holder of this post will report to the Campaign Section in the Earth and Mission Science Division within the Science, Applications and Climate Department of the Directorate of Earth Observation Programmes. In the execution of the tasks, the holder of this post will work in close cooperation with other staff of the Division and the Directorate of Earth Observation Programmes. The Earth and Mission Science Division is a dynamic RD team leading research and development activities, in partnership with European and international industry and academia, aiming at advancing science, developing future missions, novel applications, supporting industry growth and contributing to maximize the science impact of existing and future missions. Interested candidates are encouraged to visit the ESA website www.esa.int Fields of activitiesresearch The partitioning of incoming radiation into plant transpiration, soil evaporation and sensible heat flux is key for the accurate representation in weather and climate models. The representation of these processes in these largescale models is still one of the largest sources of uncertainty in present and future scenarios and therefore it requires new approaches. In short, the components of radiation, surface responses and turbulent exchanges processes need to be treated with a holistic manner in order to understand and represent the landatmosphere interface. This approach emphasizes that the carbon and water cycles are very closely linked over land. Particularly relevant is how vegetation regulates the carbon dioxide assimilation and its transpiration, and the atmospheric feedbacks. This vegetation response depends on the plant stress, and the atmospheric moisture deficit, but also on radiation perturbation and surface heterogeneities. Several existing e.g. Sentinel2Sentinel3 and future missions e.g. FLEX, BIOMASS are addressing related topics. Furthermore there is a potential that High Priority Copernicus Missions HPCM e.g. LST, LBand SAR will aid in the holistic treatment of relevant processes. During summer 2018 the FLEXSense campaign is aiming at combining relevant, satellite, airborne and groundbased data in such a holistic manner. The basic objective of the campaign is to serve as a measurement and science benchmark for existing or upcoming missions with a strong focus on optical and radar remote sensing. An original aspect of the proposed work is the intensive use of airborne remote sensing products e.g. HyPlant, TASI, LBand SAR together with existing satellite data e.g. Sentinel23ab. In a first stage, together with ground truth observational data, these products will be employed to processdriven development, to constrain numerical experiments performed with a singlecolumn model and to validate the experiments. By utilizing the high spatial resolution data and frequency representative for coarser resolution will enable the candidate to determine the state of different ecosystem at the plot scale closely related to static heterogeneity, but also sudden changes on the vegetation responses. In a second stage, this remote sensing data can be assimilated to improve the assumptions and performance of the mechanistic models representing photosynthesis and stomatal aperture. Due to its very innovative concept and unique data, the full exploitation of the gathered campaign data from FLEXSense 2018 will require a dedicated effort to explore its full potential from a scientific perspective. In this context, the candidate will be involved in three main activities Perform model simulations with a state of the art singlecolumn soilvegetationatmospheretransfer model at the core sites of the campaign for at least one growing season. Carry out a dedicated research focusing on the scientific exploitation of the FLEXSense 2018 campaign data with special focus on the underlying physical processes, fostering new science results for the synergistic use of observations from existing and future missions. Support the scientific and technical supervision of science projects, carried out by external teams of experts and scientists, addressing mainly vegetation processes process understanding and characterization, enhancing models and the study of the processes and interactions between the vegetation and the lower atmosphere.
