The WAVECHASM (Wave-Induced Transport of Chemically Active Species in the Mesosphere and Lower Thermosphere) project, funded by the NERC in the UK and the NSF in the US, will bridge the gap between high-resolution regional models and global climate models in representing transport of constituents by gravity waves. It will contribute to a much deeper understanding of the key small-scale wave-induced constituent transport processes (advection, turbulent mixing, dynamical transport and chemical transport), their global characteristics and their impact on atmospheric chemistry.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-GB>By making use of a recent novel theoretical approach and developing this to incorporate these transport processes into a global atmospheric chemistry model (NCAR’s WACCM), this project will significantly enhance our ability to simulate the global constituent structure of the upper atmosphere. We will focus on the mesosphere and lower thermosphere (MLT, between 70 and 120 km), which is sensitive to upward propagating atmospheric waves from below, and solar radiation and energetic particle precipitation (i.e. space weather) from above, and is where interplanetary dust particles ablate. This role will be based at the University of Leeds (UK) but you will be expected to visit our project partners at the University of Colorado (Boulder, USA) twice during the project, for two weeks at a time.</span><span lang=EN-GB style='font-family:"Times New Roman",serif'><o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-GB>You will have a PhD (or have submitted your thesis before taking up the role) in meteorology, atmospheric physics, atmospheric chemistry, applied mathematics, geophysics or a closely allied discipline, together with a strong background in computer programming, code development and using large numerical codes and/or datasets.
