MetEOC-1

Overview

Climate forecast models are underpinned by remotely sensed data, but a factor of 10 improvement in measurement accuracy was required to discriminate between natural variabilities in climate and the ‘anthropogenic‘ (human-caused) contributions. Improved accuracy would result in improved climate forecasts and increased confidence in adaptation and mitigation policies.
The project provided new techniques and facilities to allow significant improvements to be made to the calibration and validation of instruments used to collect the data to better understand climate change. As these techniques started to be used to calibrate sensors, more robust information and advice could be delivered to policy makers, supporting far-reaching socio-economic decisions on mitigating and adapting to climate change.
