LSGI Visiting PhD Student won the Prestigious “Zhu Kezhen” Prize from the Hong Kong Meteorological Society

Mr. Mingchen Zhu, a visiting PhD student from the Micro-Laboratory of Atmospheric Research and Geomatics Engineering (Micro-LARGE), Department of Land Surveying & Geo-Informatics (LSGI), the Hong Kong Polytechnic University (PolyU), has won the prestigious “Zhu Kezhen” Prize for the year 2021 from the Hong Kong Meteorological Society (HKMetS). The soon-to-be PhD graduate from the Southeast University, Nanjing, Mainland China, did 6-month visiting research in 2018 at Prof. George Liu’s Micro-LARGE Lab, an internationally recognized group for atmospheric water vapor observation, modeling, calibration and evaluation using advanced multi-sensors of satellite- and land-based instruments.  The “Zhu Kezhen” Prize is given only when one meritorious publication in the field of meteorology has been identified. This prize is set to commemorate the outstanding service of the founding Chairman, Mr. Patrick Sham Pak, to the Hong Kong Meteorological Society and in honour of the distinguished Chinese meteorologist, Zhu Kezhen. The prize comes with a certificate and cash HK$1,000. Mr. Mingchen Zhu is the 2nd recipient from the Micro-LARGE Lab.  The prize winning paper “Zhu M, Liu Z, Hu W (2020). Observing Water Vapor Variability During Three Super Typhoon Events in Hong Kong Based on GPS Water Vapor Tomographic Modeling Technique. Journal of Geophysical Research: Atmospheres, 125(15). https://doi.org/10.1029/2019JD032318.” was published in 2020 at the American Geophysical Union (AGU)’s Journal of Geophysical Research: Atmospheres by Mingchen Zhu and his supervisors Prof. George Liu at PolyU and Prof. Wusheng Hu at Southeast University. This study for the first time numerically characterizes the water vapor spatial and temporal variations during the life cycle of three super typhoons and demonstrates the effectiveness of using GPS/GNSS water vapor tomographic technique to study water vapor evolution during super typhoon events. This research allows forecasters to have a better understanding and forecasting of the water vapor spatial and temporal variations during tropical cyclones. Congratulations!

Signing of WSD Q-Leak’s MoU on collaboration on education and research

On 29th November 2021, Prof. CHEN Wu, Head of LSGI and Mr. MA Hon-Wing, Wilson, Assistant Director/Development from Water Supplies Department (WSD) of HKSAR Government signed a MoU about the use of the 24,000 sq. ft Q-Leak in Tsing Yi North Service Reservoir. Designed by the Associate Head, Ir Dr. Wallace Lai of LSGI, construction of Q-Leak was completed in late July 2021, and has become the first training hub in the world for providing holistic solutions for diagnosing underground pipe leakage. Jointly with WSD, LSGI will contribute to develop technologies and artificial intelligence/machine learning approaches. The Q-Leak will be a showcase to rest of the world how underground leak can be detected and diagnosed. Two parties will also join to provide education to  PolyU students, researchers and high school students through different STEM program.
