Dr Rob Parker

NCEO Leader and Research Fellow for ESM and Climate-Carbon Data Evaluation

School/Department: Physics & Astronomy, School of



My research interests centre around improving our understanding of key terrestrial processes relevant to climate change, in particular related to the carbon cycle, methane and wildfires.

My current position is as Research Fellow and NCEO Leader for Earth System Model and Climate-Carbon Data Evaluation for the National Centre for Earth Observation, based at the University of Leicester. I have over 15 years’ experience in using satellite data to retrieve concentrations of atmospheric constituents and analysing them to improve our understanding of the carbon cycle. I developed key satellite methane data products which are extensively used by the community for better understanding the global methane budget. I have expertise in using satellite data for evaluation of land surface and climate models and was awarded an international European Space Agency (ESA) Living Planet Fellowship on this topic.

I work as part of the UK Earth System Modelling Core Group, leading NCEO activities in climate model evaluation. I represent UKESM on the ESA Climate Modelling User Group. I currently lead several Digital Twin activities that bring together Earth system modelling, Earth Observation and Machine Learning to improve our understanding and predictive capabilities for the Earth system and the response to climate change.

I currently co-supervise 3 PhD students in Earth Observation at University of Leicester. I have previously supported the supervision of 5 students who have gone on to achieve their PhD and moved into successful careers including as founder of their own environmental company, working in investment banking and continuing to work in research (UK academia and NASA).

Current students:

  • R Barrio Guillo - Detecting Methane Hotspots from Space
  • N Kalaitzi - The Carbon Cycle of Urban Areas
  • D Orr - Satellite Observations of CO2 in Support of the Paris Agreement for Emission Reduction
