    Episodic nature of wet deposition of acidic material at a site in south-east England (1997)
    Springer
    Water, air & soil pollution 96 (1997), S. 73-91 
    Details
    ISSN: 1573-2932
    Keywords: acid deposition episodes ; acid rain ; back trajectory analysis ; precipitation scavenging ; sub-event chemistry ; sub-event sampling
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract The causal factors for episodic deposition of acidic material in rainfall cannot be fully understood from conventional daily network data. A brief review of the meteorological conditions leading to episodes is given. A definition of ‘episodicity’ was considered and applied to a 6 month data set collected at high temporal resolution using a microprocessor based acid rain monitor at a site in south-east England. The deposition was highly episodic for all of the measured variables when data from individual rain events were considered. Combining the data into daily averages resulted in changes of episodicity classification for several chemical species. A large percentage of the total deposition recorded during the field experiment occurred in a 5 day period when there was an independent report of ecological damage at other locations in England. Nitrate deposition showed the highest degree of episodicity with 51% of the 6 month total occurring during the 5 day episode. Meteorological details of the transport and wet deposition processes during this period were examined. Back trajectory analysis indicated that the episode was the result of pollutant loading in eastern and central Europe of the air masses reaching the site together with an absence of upwind precipitation scavenging.

    Acid deposition during two contrasting frontal rainfall events (1997)
    Springer
    Water, air & soil pollution 96 (1997), S. 93-106 
    Details
    ISSN: 1573-2932
    Keywords: acid deposition ; acid rain ; back trajectory analysis ; precipitation events ; precipitation scavenging ; sub-event chemistry ; sub-event sampling

    Notes: Abstract Analysis of the chemical composition of rain at high temporal resolution provides additional information on wet deposition processes. High resolution data was obtained using a microprocessor-based acid rain monitor at two sites in SW Scotland and SE England. Meteorological details of the transport and wet deposition processes during two frontal rain events were examined and related to rainfall composition. Rapid depletions of ion concentrations during heavy rainfall in the first event were interpreted using a rainfall scavenging model. The sub-event data for the second event showed the influence of frontal discontinuities. Increasing ionic concentrations during this second event were attributed both to the change in air mass, and to diminished upwind precipitation scavenging.
