AB: During March 2006 the Optical Remote sensing group at Chalmers University of Technology participated in the MCMA-2006 field campaign in Mexico City, performing measurements of air pollution using a set of different optical remote sensing instruments. This poster gives an overview of the techniques applied and results obtained. The techniques applied were:

1. Solar Occultation FTIR and UV spectroscopy from fixed locations throughout the MCMA area, yielding total columns of CO, CH₂O, SO₂ and NO₂.
2. Long Path FTIR measurements from site T0 located in the north part of central Mexico City. With this instrument line-averaged concentration measurements of CO and CO₂ was obtained in parallel with DOAS measurements performed by other partners.
3. MAX-DOAS measurements from site T0, yielding total column and spatial distributions of SO₂ and NO₂.
4. Mobile DOAS scattered Sunlight measurements of total columns of SO₂ and NO₂ in and around the MCMA area.
5. Mobile and stationary DOAS measurements in the vicinity of Tula and Popocatépetl in order to quantify emissions from industry and volcano.
