Site Description

From previous research undertaken into pollution levels within the Swansea conurbation, one of the major influences on ambient air quality is weather conditions. This effect is further enhanced by the topography of the lower Swansea valley. There is a need therefore, for high quality local meteorological data from the urban area under study to increase the understanding of the complex wind variations due to topography and land/sea effects.

The mast is located within the Hafod Air Quality Management area and is approximately 30m above seal level with the bottom of the valley floor being approximately 10m above sea level.

This 30m mast will allow data to be gathered with an integration period of 1 minute measuring temperature and wind profiles in the lowest atmospheric layer in the valley. All data will be utilised by various air quality models including Nowcaster which is primarily a street canyon air quality model computing pollution loadings on each individual road link.
