Using MERIS data in the calculation of NO2 airmass factorsJ. Leitão, A. Heckel, A. Richter, T. Dinter, W. von Hoyningen-Huene, A. Kokhanovsky, and J.P. Burrows Accent Workshop Tropospheric NO2 measured by satellitesKNMI, De Bilt, The Netherlands, 10-12 Sept 2007
Focus of work – The improvement of the a priori assumptions used for the computation of the NO2 airmass factor (AMF). Why? – Aerosol and albedo can have great impact on NO2 AMF and currently the spatial and time variability of these are not considered in the AMF computation. What is the plan? – Include in the retrieval method data that can be continuously updated (real measurements and dynamical “climatology”). • How to do? • Using data of MERIS instrument • BAER algorithm retrieves AOT data, surface reflectance values and also cloud cover information • New dataset to be incorporated in the retrieval method of tropospheric NO2.
