Satellite Informatics System for Surface Particulate Matter
Distribution
People are most concerned about their local
environment. To get their attention about Air Quality (AQ), it
is important to have specific AQ information down to their
neighborhood. Currently, this is not available in HK, or
anywhere else.
Based on satellite remote-sensing data, we have developed
algorithms to calculate the surface Particular Matter (PM)
distribution with resolution down to 1 km. The validity of our
algorithms has already been proven with air quality monitoring
station data from the EPD. |

Study of Wind Energy Resources over Hong Kong
The purpose of this Study of Wind Energy Resources over Hong Kong website is to promote a better understanding of the potential to use wind energy in Hong Kong. The main feature of the Study of Wind Energy Resources over Hong Kong website is an interactive map that can be used to provide estimates of wind speed and energy in Hong Kong during any period from 1 January 2004 to 31 December 2006. Estimates can be given for specific points, or for selected areas. The website also provides maps illustrating Hong Kong's land classifications as well as the distribution of wind resources within the city. |

Removal of
Organic Aerosols and Odors in Cooking Exhaust
A large amount
of cooking fume and odor are generated in the restaurant
kitchens. This cooking fume has been found to be harmful to
human if the concentration is high. It is also a serious air
pollution problem in Hong Kong. A removal system based on the
integration of novel and matured technologies is proposed to
remove this problem. The system uses a laminar-flow hood with a
proven oil droplet filter, to remove most of the fume (~70%)
generated during cooking. The remaining fume and odor are
concentrated by an adsorption/ desorption unit and then
destroyed by thermal degradation in the burner of the gas stove.
Any trace combustion products can be catalytically removed, if
necessary. |

Mobile Real-time Air Monitoring
Platform (MAP)
MAP
stands for Mobile real-time Air monitoring Platform,
a project funded by the Hong Kong Jockey Club and it is a new
concept to obtain high intensity and continuous air quality data
from a moving platform. MAP is a vehicle equipped with
state-of-the-art equipment and instruments to monitor air
pollution on the road in a real-time, in situ
mode, in contrast to the conventional stationary techniques.
Real-time mapping is more cost effective than the stationary
because of the high quality and intensity of the data and its
ability to cover a much larger territory in a short time.

Aerosol
Generated During Toilet Flushing
Since the outbreak of SARS in spring
2003, concern has arisen over hygiene in washroom. The
institute thus launched a study on aerosol generated around
toilet bowl during flushing, in hope of obtaining an insight
into the possibility of spread of bacteria at the flushing
progress.

Integrated
Assessment System for Renewable Energy Resources
We propose to create a common platform for integrated assessment
of the quantity and quality of these RE resources over Hong Kong
and Guangdong. The system will help our professionals to
provide more specific RE resources assessment and
recommendations to their clients, and also help our industries
to better plan their investments as they try to enter into this
rapidly growing market in Guangdong. |

River Estuary Pollution Project
(PREPP)
The objective of the Pearl River
Estuary Pollution Project (PREPP) is to use a combination of
traditional and new technologies to gain a solid understanding
of the status of selected toxic pollutants, sediment,
phytoplankton and nutrient levels in the Pearl River Estuary.
Given the dramatic growth of industry and population in the
area, this information is urgently needed to ensure that
government pollution monitoring and control strategies are in
line with the most serious threats to ecology and human health. |

Pollution Index Forecast Model
(APIFM)
In Hong Kong, there are more than 6.8 million people
in an area of about 1100 km2, and an additional 20
million population in the surrounding Pearl River Delta area.
The rapid growth of industry, the population and the overall
economy in H.K. exerted substantial pressure on the environment
in this region. The 1998 annual report from the HK
Environmental Protection Department (EPD) pointed out the
'continuing poor air quality over Hong Kong', and also suggested
that 'Hong Kong and mainland China may affect each other's air
quality, but to what extent depends very much on the weather
conditions and the type of pollutants involved'. The continuous
monitoring and understanding of air quality (AQ) is therefore a
subject of interest for both the government and the public. |

Wind Monitoring System (WMS)
The natural topography and the terrain on Lantau
Island cause strong wind along the railway track to be amplified
by wind gaps. The wind may reach intensities that may hamper the
normal operation of the airport train service. Meteorological
sensors are installed at strategic locations for on-site
measurements and small-scale numerical flow field modeling.
The system is designed for maximum reliability and minimum
down-time. It is a robust system with redundant hardware and
control processes that automatically handle defective sensors
and/or data communication without interrupting the real-time
data collection. Under very extreme conditions when sensors are
not in operation, the system has the intelligence to estimate
the wind condition by regression using historical data and data
from the nearby sites.
