| Abstract |
In this study, the processing of SEVIRI data for marine applications developed for the southern North Sea by Neukermans et al. (2012, 2009) is generalized. The updated processing can be applied to any region in SEVIRI’s full viewing disk (centred on 0°N, 0°E) where the marine signal is sufficiently high (turbidity > ~1 FNU). Rayleigh and aerosol look-up-tables now account for all possible viewing and sun geometries. Parameters that can be derived from marine reflectance in a broad red band (560-710 nm) such as turbidity and suspended matter concentration can be studied at high temporal resolution. Marine reflectance from SEVIRI compared well with marine reflectance from MODIS-Aqua for several European and African coastal waters. The capabilities of high frequency imagery are well illustrated. For example, cloud clearing capabilities show improved coverage of a coccolithophore bloom and short-term changes in turbid coastal waters are observed on cloud-free days. |
