Earth Observation

Remote sensing obtains information about the ocean from a distance, usually from satellites or aircraft, and can be used to measure a wide variety of parameters from ocean temperature to plankton dynamics. These observations from space provide unique information which greatly aids understanding and management of our environment and are vitally important because they can observe vast areas of the Earth that are difficult to access and sample using traditional methods.

Our activities are centred on the remote sensing of the Earth’s ocean and atmosphere, whilst not ignoring the intimate connections between the ocean, the atmosphere and terrestrial, estuarine and lacustrine environments. We have a focus on several research areas:

  • Phytoplankton dynamics and ocean colour
  • Validation of Earth observation data
  • Exploitation of Earth observation data
  • Provision of EO services to NERC and European agencies
 

Finally, the group is also exploiting new capabilities from the ESA Sentinel programme for innovative applications, and, potentially, commercial services, such as for the aquaculture industry, working with PML Applications Ltd.

PML's use of satellite data

Making a difference

Our Earth Observation group enjoys a global reputation and has a proven track record in both pure and applied Earth observation science, and comprises experts in many complementary fields including remote-sensing, physics, meteorology, engineering, data visualisation and computing. PML also develops applications to address environmental questions, provide services for others and is working to commercialise its research via PML Applications Ltd.

With a flexible approach to problem solving, scientific investigation and interpretation, and a willingness to share its expertise and to work co-operatively world-wide our Earth Observation group is a partner in a multitude of national and international projects, latterly with the European Space Agency (ESA) and the Copernicus Programme, as well as NERC, BBSRC and Defra research programmes.
