PhD-project title: Satellite retrieval of phytoplankton biomass
Global retrieval of phytoplankton biomass by combining information from high-spectrally and high spatially resolved satellite data in order to determine phytoplankton biomass from satellite data with higher accuracy.
The goal mentioned above will be achieved by these steps:
- DOAS-retrieval of phytoplankton functional-types using SCIAMACHY data and build-up of one year data set of the distribution of various phytoplankton functional types.
- Validation of the distribution of various phytoplankton functional types retrieval from SCIAMACHY.
- Retrieval of an improved chl-a product from MERIS using the info on varying phytoplankton absorption and phytoplankton groups and on diffuse attenuation derived from SCIAMACHY data to determine more accurate chl-a from MERIS.
- Validation of new chl-a retrieval from MERIS and global processing of chl-a from MERIS
