InSAR

Nottingham University’s contribution to the project is the analysis of peatland condition and change in condition using peatland surface motion, also known as ‘bog breathing’.  This is measured using interferometric synthetic aperture radar (InSAR).  Surface motion, as measured in the field is an indicator of condition and resilience, with bogs in good condition displaying greater seasonal amplitude and resilience to drought.  Remote sensing of surface motion enables this understanding to be assessed at a landscape scale and the impacts of events e.g. droughts or restoration to be evaluated.  In the MOTHERSHIP project the InSAR derived results provide a bridge between the scales of field observation and ecohydrological modelling and that of the land surface models.
