博士项目：利用图形处理器与机器学习技术研究云层及野火烟柱中的三维辐射现象

该博士项目致力于开发一种蒙特卡洛光线追踪算法，以模拟云层与野火烟柱中的三维辐射相互作用，从而提升气候和太阳预报的精度。申请者将与计算机科学同行合作进行 GPU 优化工作，并研发机器学习去噪技术，以加快光线追踪算法的运行效率。

Your job: This PhD project is part of ORCRIST: Optimized Ray-tracing for Cloud-Radiation Interaction Simulations in 3D using GPUs and Machine Learning, funded by the NWO Open Technology Programme. Sunlight and heat radiation move through the atmosphere in three dimensions, yet almost every weather and climate model still treats radiation as a purely vertical process. We want to change that. As a PhD candidate in Wageningen, you will help build the first Monte Carlo ray tracer for the atmosphere that is fast enough for forecasting, and use it to find out how 3D radiation shapes clouds, solar energy availability, climate sensitivity and wildfire plumes. You will work in a tandem with a fellow PhD student in computer science at Leiden University, who focuses on GPU optimization, while you lead the physics. Together you will develop a machine-learning denoiser that brings the ray tracer to operational speed. Your research has a clear route to society: throughout the project you will work with a user committee of KNMI, weather forecasting company Whiffle, TNO, software company VORtech and Columbia University. Your duties and responsibilities include: Setting up three benchmark simulations in the GPU-accelerated model MicroHH: solar energy forecasting, tropical climate, and a real wildfire plume. Developing a 3D thermal radiation solver within the RTE-RRTMGP-CPP ray tracer, including smart strategies for sampling radiation sources. Quantifying how 3D radiation changes clouds, surface irradiance and plume dynamics compared to conventional 1D radiation. Co-developing a physics-informed machine-learning denoiser with your Leiden colleague, and evaluating it together with the user committee in operational settings. Publishing your results in leading journals and presenting them at international conferences and to users from the field. You will work here: We are: ​The mission of Wageningen University & Research is “To explore the potential of nature to improve the quality of life”. Under the banner Wageningen University & Research, Wageningen University and the specialised research institutes of the Wageningen Research Foundation have joined forces in contributing to finding solutions to important questions in the domain of healthy food and living environment. With its roughly 30 branches, 7,600 employees (6,700 fte) and 13,100 students and over 150,000 participants to WUR’s Life Long Learning, Wageningen University & Research is one of the leading organisations in its domain. The unique Wageningen approach lies in its integrated approach to issues and the collaboration between different disciplines.

In addition to these first-rate employee benefits, you will receive a fully funded PhD position and you will be offered a course program tailored to your needs and the research team. The gross salary for the first year is € 3204,- per month rising to € 4051,- in the fourth year in according to the Collective Labour Agreements for Dutch Universities (CAO-NU) (scale P). This is based on a full-time working week of 38 hours. We offer a temporary contract for 18 months which will be extended for the duration of the project if you perform well. We encourage development and internal mobility within our organisation. Our recruitment and selection policy sets out the conditions that apply specifically to you as a (former) employee. If you have any questions, we are happy to help. You will work on the greenest and most innovative campus in the Netherlands, in an international and open working environment. Coming from abroad: Wageningen University & Research is the university and research centre for life sciences. The themes we deal with are relevant to everyone around the world and Wageningen, therefore, has a large international community and a lot to offer to international employees. Because we expect you to work and live in the Netherlands our team of advisors on Dutch immigration procedures will help you with the visa application procedures for yourself and, if applicable, for your family. Feeling welcome also has everything to do with being well informed. Wageningen University & Research's International Community page contains practical information about what we can do to support international employees coming to Wageningen. Furthermore, our Welcome Center can assist you with any additional advice and information about for example housing, opening a bank account, dual career programs or schooling. Finally, certain categories of international staff may be eligible for a tax exemption on a part of their salary during the first five years in the Netherlands.
