Measurement of trace gas emissions using Mobile-DOAS and UV-cameras at Montevideo Harbour

摘要

The growth of vessel traffic has increased atmospheric pollution affecting not only the port areas, but also the surrounding cities. For this reason, initiatives have been taken to regulate these emissions at international level. As far as our country is concerned, an effort is also being made to have tools that allows the monitoring of emissions. In this work we present results of monitoring carried out using the DOAS technique in two ways. On one hand, high resolution spectra acquired from mobile platforms and zenith observations were analysed. From the available spectral region (315-460 nm), total columns of NO_2 and SO_2 were obtained and their provenance identify. Afterwards, we calculate the emitted flows. On the other hand, sensitive cameras were used in the UV region with selective filters, in order to obtain SO_2 images and therefore, calculate the emission flows of specific vessels.
