Conclusions Horizontal gradients can be determined from 4-azimuth MAX- DOAS observations => information on location of sources 3D-distribution of the sensitivity of MAX-DOAS depends strongly on wavelength and aerosol load horizontal area with box-AMF > 1 ranges typically from ~3 km to ~30 km spatial resolution of future satellite instruments maches that of MAX-DOAS observations (or is even finer)
