An instrument based on the Multi Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) technique was designed and constructed to measure scattered sunlight in UV-visible region at different elevation angles. Slant column densities (SCDs) of specific gas absorbers such as nitrogen dioxide (NO2) formaldehyde (HCHO) are derived from measured spectra. In this contribution, technical characteristics performance instruments, their deployment a newly formed observational network within metropolitan area Mexico City, some results retrieved NO2 HCHO SCDs presented. These measurements provide more insight vertical spatial distribution these key atmospheric pollutants temporal variability, which also serve basis for present future satellite validation studies.
