Abstract
The ToTAL -DOAS (Topographic Target Light s cattering – Differential optical Absorption Spectroscopy) is a novel atmospheric monitoring technique. The aim of our work has been enhancing a prototype, previously assembled within our research group, adding to it a temperature control and developing specific control software. The whole system offers the possibility of two dimension movement for spectra acquisition with a telescope of a field of view of approximately 0.03°, which let in signals in the near-UV and visible spectral range. The enhanced DOAS system is intended to be located on the roof of our faculty building to monitor SO2 and NO2 traces above the city of Montevideo. We are presenting the results of device's characterization.
