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，研究大气与山脉、山谷和海岸线等复杂地形之间的相互作用。我感兴趣的是基本的动力学和气候学的相互作用，以及这项工作的环境应用，如空气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关于以下主题的工作：* 气流动力学，以评估加拿大西海岸沿着的海上风力发电潜力（与博士生Bakri合作），使用合成孔径雷达（SAR）数据、浮标和模型。空气质量以多管齐下的方式确定空气污染源对我们呼吸的空气的贡献。与博士生Tereshchak合作，我们将在加拿大野外条件下测试最近开发的低成本连续空气质量传感器，并将其集成到多污染物移动的监测平台中，该平台将部署在多个固定位置以及车辆和无人机上，以绘制整个区域的空气质量。使用国家的最先进的空气质量模型，与博士生Onwukwe，我们将努力了解目前和未来的威胁，在西北BC省的空气质量由于液化天然气行业的未来发展。与博士生伊斯兰教，利用卫星遥感甲烷和全球化学运输模型，我们将获得一个独立的自上而下的估计甲烷排放量从加拿大西部的石油和天然气开发地区。由于甲烷是一种重要而强大的温室气体，这将有助于了解加拿大的温室气体排放量，并实现最近加拿大-美国协议中规定的40-45%的减排目标。空中生物群在风中的运动通过了解控制它们何时出现的气象学和携带它们的风来预测山松甲虫从一年到下一年的运动（与合作者Chen）。这将产生一个预测该流行病从一年到下一年的变化的模型。冰川质量平衡的气象驱动因素，以了解冬季雪及其转化和再分配如何滋养哥伦比亚盆地的冰川（与共同监督的博士生Mortezapour和合作者Menounos）。这将有助于模拟气候变化导致的高山冰川的命运。
