Earth Observation & Climate Earth Observation & Climate

The Earth Observation, Climate and Optical scientists research a wide range of areas relating to the application of metrology to Earth Observation, from the calibration of optical instruments to the uncertainty analysis of biophysical products.

Earth Observation & Climate Change

NPL's Earth Observation and Climate Change activities include providing traceable measurements for Earth Observation Instrumentation and support for Vicarious Calibration. This involves many collaborations, which are providing international support for our satellite mission proposal ‘TRUTHS’.

In recent years, there has been an increasing demand for improved accuracy and reliability of Earth Observation (EO) data, stimulated not only by our desire to understand better the workings of our planet and the cause and impact of climate change, but also because improvements in models allow us to discriminate better between data. A further driver is the increasing reliance on the combination of data from different sensors and sources (satellites, aircraft and in-situ) to establish more sophisticated data products.

It is also essential that all measurements and associated instrumentation used for any quantitative purpose in remote sensing be fully traceable to SI as part of the Quality Assurance process, as recommended by the Committee of Earth Observation Satellites (CEOS) in 2001.

To achieve our objectives, we work closely with many partners, as well as the Centre for Carbon Measurement and the Global Sensing and Satellite Centre (GloSS)

Measurement needs

Please tell us about any measurement needs you may have. Some examples of these might be:

  • Issues relating to product inspection
  • Issues relating to process control
  • Training requirements
  • Obtaining specialist calibration or testing support
  • Problem solving on measurement issues
  • Demonstrating or assessing measurement system or product performance

Your input will help us to develop our future work.
