based on EUMETSAT images could be elaborated. The analysis should also include other<br />
constraints: minimization of air mass fraction and glint avoidance.<br />
• Data processing. Ocean colour measurements from GeoOculus are characterised on one<br />
side by high frequent, spatial high resolution, which are superior to current LEO orbit data,<br />
on the other side by radiometrically less favourable conditions, including probably lower<br />
SNR, possibly spectral and spatial misregistration between bands and a very large viewing<br />
angle at higher latitudes.<br />
For detailed assessment and identification of required developments of data processing<br />
methods, the relevant processing chain should be analysed for sensibility to the<br />
characteristic of geostationary observation.<br />
Beside the traditional approach it should be studied to develop products which require<br />
simplified processing. The processing would either use directly TOA radiance without explicit<br />
atmospheric correction, or perform a simplified AC.<br />
