Resolving uncertainty in climate change data

Further Information

Recorded: 14 October 2006

Speaker: Dr Nigel Fox, NPL

Related: TRUTHS Research

The technologies used in current Earth Observation satellites have intrinsic uncertainties (measurement errors) that do not matter for individual missions but matter a great deal when we need to study the small incremental changes over long periods of time that are typical of Climate Change.

Dr Nigel Fox describes the need for a calibration laboratory in space (called TRUTHS), that would enable scientists to correct errors in the data from other satellites. TRUTHS or a similar capability would enable scientists to improve the computerised climate models, helping us to better understand Climate Change and the impact of any measures we might take to reduce Global Warming.
