Short summary
We describe the University of Colorado 2-D-MAX-DOAS instrument and a retrieval to measure 3-D distributions of NO2. The spatial scale over which NO2 is probed is systematically varied by measuring NO2 at three different wavelengths. This has a significant effect on the comparison with the NO2 VCD as measured by OMI. The challenges and opportunities to validate satellites under inhomogeneous conditions as well as to pinpoint hydrocarbon chemistry around the measurement site are discussed.
