Development and validation of new data products from satellite sensors and their use in the study of mesoscale processes using a variety of sensors and techniques.
Particular interests include:
- Generating altimeter products for oceanography
- New products from the ESA Explorer missions SMOS (Soil Moisture and Ocean Salinity), CryoSat II and GOCE (Gravity field and steady-state Ocean Circulation Explorer)
- Preparing for the new ESA missions, including the Sentinel missions
- Applying new data technologies to data access tools
- Use of satellite altimetry and its combination with Sea Surface Temperature, ocean colour, model data and in situ measurements
Committee and Board Memberships:
Member of the NERC Administration/Science Administration Promotion Panel
Member of the NEODAAS Advisory Committee
Chair of the NOCS Facilities Sub-Committee
