I am a meteorologist who studies the interaction between the atmosphere and complex terrain such as mountains, valleys and coastlines. I am interested in the fundamental dynamical and climatological interactions, as well as environmental applications of this work such as the movement of airborne biota and the transport of air pollutants. This proposal is to continue and extend current work on the following themes: Airflow Dynamics to assess offshore wind power production potential along Canada's west coast (with PhD student Bakri) using synthetic aperture radar (SAR) data, buoys and models. Air Quality to determine the contribution of air pollution sources to the air we breathe in a multi-pronged approach. Working with PhD student Tereshchak, we will test recently developed low-cost continuous air quality sensors in Canadian field conditions and integrate these into a multi-pollutant mobile monitoring platform that will be deployed at multiple fixed locations as well as on a vehicle and an Unmanned Aerial Vehicle to map air quality across an area. Using state-of-the-art air quality models, with PhD student Onwukwe, we will work to understand current and future threats to air quality in northwest BC due to future development of the Liquified Natural Gas industry. With PhD student Islam, using satellite remote sensing of methane and a global chemical transport model, we will obtain an independent top-down estimate of methane emissions from the oil and gas development regions of western Canada. As methane is an important and potent greenhouse gas, this will contribute to understanding Canada's greenhouse gas emissions and to meeting the targeted 40-45% reductions in the gas, arising from the recent Canada-US agreement. Movement of Aerial Biota by the Wind to predict the movement of Mountain Pine Beetles from one year to the next by understanding the meteorology that controls when they emerge and the winds that carry them (with collaborator Chen). This will result in a model to predict the movement of the epidemic from one year to the next. Meteorological Drivers of Glacier Mass Balance to understand how winter snow and its transformation and redistribution acts to nourish glaciers in the Columbia basin (with co-supervised PhD student Mortezapour and collaborator Menounos). This will contribute to modelling the fate of alpine glaciers due to a changing climate.

我是一名气象学家，研究大气与复杂地形（如山脉、山谷和海岸线）之间的相互作用。我对基本的动力学和气候相互作用以及这项工作的环境应用感兴趣，例如空气中生物群的运动和空气污染物的运输。该提案将继续并扩展目前在以下主题上的工作：气流动力学（与博士生Bakri一起）利用合成孔径雷达（SAR）数据、浮标和模型来评估加拿大西海岸的海上风力发电潜力。以多管齐下的方法，确定空气污染源对我们呼吸的空气的贡献。我们将与博士生Tereshchak合作，在加拿大的现场条件下测试最近开发的低成本连续空气质量传感器，并将这些传感器集成到一个多污染物移动监测平台中，该平台将部署在多个固定地点，以及车辆和无人机上，以绘制整个地区的空气质量地图。利用最先进的空气质量模型，与博士生Onwukwe一起，我们将努力了解液化天然气行业未来发展对不列颠哥伦比亚省西北部空气质量的当前和未来威胁。与博士生Islam一起，我们将利用卫星甲烷遥感和全球化学运输模型，对加拿大西部石油和天然气开发地区的甲烷排放量进行独立的自上而下的估计。由于甲烷是一种重要且有效的温室气体，这将有助于了解加拿大的温室气体排放情况，并有助于实现最近美加协议中提出的减排40-45%的目标。通过了解控制山松甲虫出现时间和携带它们的风的气象学，预测山松甲虫每年到下一年的运动（与合作者陈）。这将产生一个模型来预测流行病从一年到下一年的运动。冰川物质平衡的气象驱动因素，以了解冬季积雪及其转化和再分配如何滋养哥伦比亚盆地的冰川（与共同指导的博士生Mortezapour和合作者Menounos）。这将有助于模拟气候变化对高山冰川命运的影响。
