About the Book

Sharing is caring!

Air pollution has received considerable attention by local and global communities (Wald et
al, 1999). Many major cities have established air quality monitoring stations but these
stations tend to be scarcely distributed and do not provide sufficient tools for mapping
atmospheric pollution since air quality is highly variable (Wald et al, 1999). Satellite remote
sensing is a valuable tool for assessing and mapping air pollution as satellite images are able
to provide synoptic views of large areas in one image on a systematic basis due to the
temporal resolution of the satellite sensors. Blending together earth observation with
ground supporting campaigns enables the users or governmental authorities to validate air
pollution measurements from space. New state-of-the-art ground systems are used to
undertake field measurements such as Lidar system, automatic and hand held sunphotometers
etc. The rise of GIS technology and its use in a wide range of disciplines
enables air quality modellers with a powerful tool for developing new analysis capability.
Indeed, thematic air pollution maps can be developed. Moreover, the organization of data
by location allows data from a variety of sources to be easily combined in a uniform
framework. GIS provides the opportunity to fill the technical gap between the need of
analysts and decision-makers for easy understanding of the information.
