WebMAX-DOAS aerosol extinction profiles have been compared to smoothed extinction profiles from a sun photometer (Frieß et al., 2011) and aircraft aerosol profiles (Wagner et al., 2011). Near-surface MAX-DOAS retrievals of aerosol extinction have been compared with in situ measurements of aerosols (Zieger et al., 2011). WebMass photometry is a revolutionary new method for analysing molecules. It enables the accurate mass measurement of single molecules in solution, in their native state and without the need for labels. This approach opens up new possibilities for bioanalytics and research into the functions of biomolecules. The amount of light scattered by a ... the lindworm story
