<span style="font-size:12.0pt;font-family:"Times New Roman",serif;mso-fareast-language:EN-GB">The first project is WAVECHASM (Wave-Induced Transport of Chemically Active Species in the Mesosphere and Lower Thermosphere), funded by the
</span><span style="font-family:"Times New Roman",serif">NERC</span><span style="font-size:12.0pt;font-family:"Times New Roman",serif;mso-fareast-language:EN-GB"> in the UK and the NSF in the US. It aims to 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. This role will be based at the University of Leeds (UK) but the successful candidate must be willing to spend periods of time at the University of Colorado (Boulder,
USA) working with project partners. <o:p></o:p></span></p>

varibility at small-scales affects thermospheric density and how that leads to changes in atmospheric drag on satellites and space debris. It will focus on improving our ability to represent atmospheric joule heating in state-of-the-art upper atmosphere models
to enable better short-term (~24 hour) forecasting of satellite and debris orbit predictions as well as inform the long-term (100-year) predictions of the space environment population.<o:p></o:p></span></p>

<span style="font-size:12.0pt;font-family:"Times New Roman",serif;mso-fareast-language: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. Experience of working directly on research problems related to the earth’s mesosphere and lower thermosphere
would be beneficial.</span> <span style="font-size:12.0pt;font-family:"Times New Roman",serif;mso-fareast-language:EN-GB">
