%X Nitrogen dioxide (NO2) plays a very important role among the anthropogenic trace gas. The tropospheric NO2 vertical column density (VCD) maps derived have been used to study many scientific applications, such as pollution emissions and pollutant distribution. This paper reviewed the NO2 inverse algorithm, Differential Optical Absorption Spectroscopy (DOAS), from satellite measurements, and also discussed the error analysis, validation and developing trends. Significant techniques are detailed for DOAS method, such as the ring effect algorithm, stratospheric NO2 concentration algorithm and air mass factor (AMF). After displaying the different accuracies of NO2 retrieved from satellite measurements, uncertainties are discussed for model parameters including cloud, a-priori NO2 profiles, aerosol layer, and so on. There are many important issues needing to be improved. These include the tropospheric NO2 retrieval algorithm, geostationary air quality satellite, and validation from ground-based measurements, Multi-Axis DOAS, and aircraft-based instruments.
