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
