Measurement of atmospheric trace gases using solar absorption spectroscopy in the Inner Tropics — •Mathias Palm1, Cornelius Becker2, Thorsten Warneke1, Christof Petri1, and Justus Notholt1 — 1Universität Bremen — 2Meterologische Dienst Suriname
Measurements of atmospheric trace gas distributions in the inner tropics are sparse. The AG Notholt of the Universität Bremen has been active since 2004 in Paramaribo, Suriname, 6N. Until 2012 measurements were only conducted on campaigns during the dry periods in spring and autumn.
Since 2012 measurements could be extended to cover the whole year. We show the first results of whole year measurements above Paramaribo and compare them to independent measurements from satellite and some first model results. This is of interest because the inner tropical convergence zone (ITCZ) sweeps over Paramaribo and allows measurements of the southern and northern atmosphere and the transition thereof.
One trace gas, HCl, which is linked to Ozone depletion, shows since a few years a very distinct seasonal cycle. First attempts of the interpretation of those measurements will be shown and discussed.
