Remote Sensing-Based Estimation of Carbon Sequestration in Hong Kong Country Parks from 1978 to 2004

This paper estimates the amount of carbon sequestered by vegetation and soil in the country parks of Hong Kong from 1978 to 2004. It does so by comparing satellite images of each country park from 1978, 1991, 1997, and 2004, and calculating the area of woodland, scrubland, and grassland in each image. The amount of carbon sequestered in both vegetation and soil is then estimated using aggregate...

Observation of increases in emission from modern vehicles over time in Hong Kong using remote sensing.

In this study on-road gaseous emissions of vehicles are investigated using remote sensing measurements collected over three different periods. The results show that a high percentage of gaseous pollutants were emitted from a small percentage of vehicles. Liquified Petroleum Gas (LPG) vehicles generally have higher gaseous emissions compared to other vehicles, particularly among higher-emitting ...

Satellite Remote Sensing for Geologic Carbon Sequestration Field Monitoring

Carbon dioxide is one of the major greenhouse gases generated by human activities which, by virtue of its impact on global climate through “Greenhouse Warming”, are implicated in extreme environmental impacts such as more prevalent and more intense storms, bushfires, floods, droughts and heat waves. In order to constrain the growth of atmospheric CO2, Geologic Carbon Sequestration (GCS) has bee...

Hyperspectral Remote Sensing for Geologic Carbon Sequestration Field Monitoring

In order to constrain the growth of atmospheric CO2, Geologic Carbon Sequestration (GCS) has been proposed as one “clean coal” technology for mitigating the more extreme impacts of global warming. An important issue to ensure the successful storage of carbon dioxide in geologic sequestration sites is the ability to monitor these sites for possible leakage. More understanding of CO2 storage proc...
