| Summary: | Includes bibliographical references. === The term atmospheric haze is a condition of reduced visibility, caused by the presence of fine particulate matter in the atmosphere, which can originate from natural or anthropogenic sources. The "Brown Haze" is a phenomenon that is associated with Cape Town and can be described as brown coloured smog. It occurs over the winter months, mainly May to September, due to the strong temperature inversions and windless conditions that can occur during these months. These conditions lead to the build-up of pollutants emitted into the atmosphere. The Cape Town Brown Haze Phase Two study was used to obtain a detailed analysis of the atmosphere in a programme of lateral and vertical profiles through the Brown Haze. The field campaign took place from the 29th July 2003 to the 26th August 2003 around the Cape Town metropolitan region. |
