TRUTHS satellite calibration mission

NPL in space

Improving Earth observation data to drive improved climate change modelling

TRUTHS is a climate mission, led by the UK Space Agency (UKSA), which will be delivered by the European Space Agency (ESA) to enable in-flight calibration of Earth observation (EO) satellites. TRUTHS will help deliver improved confidence in Earth Observation data gathered from space and the forecasts driven by this data.

TRUTHS stands for Traceable Radiometry Underpinning Terrestrial- and Helio- Studies and will enable upgrade of the performance of the EO system, both in space and on the ground. The mission will facilitate the development of a global, climate observatory, delivering data of unprecedented accuracy with SI traceability - establishing a 'standards laboratory in space'

 
TRUTHS - An introduction

 

TRUTHS will allow rigorous testing of model forecasts to support decision-making on climate adaption strategies. The  mission will enable a 10 fold improvement in accuracy of EO data, which will, in turn, drive a halving of the time required for climate scientists to make unequivocal determinations of changes to the earth’s temperature. The mission provides 'benchmark'  measurements with uncertainties small enough that future change, from a background of natural variability, can be detected in as short a time as possible.
