Associate Professor Tristan Quaife

Associate Professor of Carbon Cycle Science

Responsibilities:

Departmental Undergraduate Admissions Tutor

Research Interests:

  • Modelling of the terrestrial carbon cycle -- focusing on the response of vegetation to climate change
  • Radiative transfer in vegetation -- including applications to optical remote sensing and retrieval of biophysical parameters
  • Data Assimilation for land surface and ecosystem models.

Research Projects

Active Research Projects:

  • I am a Principal Investigator on the National Centre for Earth Observation (NCEO). The focus of my work within NCEO is using satellite observations to test and constrain models of the land surface.
  • Through NCEO I am part of the UK Earth System Model (UKESM) Long Term Science Multi-Centre project.
  • I co-lead the TAMSAT group. TAMSAT is the University's operational rainfall product for Africa.
  • PASQUAL: an Innovate UK funded project looking at the use of satellite observations to assess pasture quality.
  • CALIBRE: a NERC funded project looking at the potential of agro-forestry to sequester green house gasses.
  • The Sentinel Synergy Study (S3) is funded by the European Space Agency and is looking at developing synergistic joint retrievals from the Sentinel-1 and Sentinel-2 missions.
  • PalEON is a long running NSF project, in which I am part of the modelling team.
Recently Completed Research Projects:

  • ERADACS: a NERC GCRF funded project, which finished in 2018, looking at enhancing resilience to drought in Africa.
  • MELODIES: a completed FP7 project to develop innovative and sustainable services, based upon Open Data, for users in research, government, industry and the general public in a broad range of societal and environmental benefit areas. The code we developed under this project is available here.

Postdoctoral & graduate student supervision

Post Doctoral staff:

  • Ewan Pinnington works on WP1 of the NCEO ODA programme and the ESA Sentinel Synergy project. He previously worked on the ERADACS project.
  • Ranjini Swaminathan works on the UKESM-LTSM developing new evaluation tools for Earth System Models.
Current PhD students:

  • Helen Johnson is based at the Met Office and is doing a part time PhD on the effect of black carbon deposition on snow with a specific focus on weather forecasts.
  • Amsalework Ejigu is working on data assimilation in JULES using the EMPIRE framework.
  • Victoria Boult is using Idividual Based Models and satellite data to look at the behaviour of African elephants. Lead supervisor: Prof Richard Sibly, Biology.
  • Kirsten Lees is researching the productivity of peatlands and how this might be observed with satellite data. Lead supervisor: Associate Prof Jo Clark, Geography.
Completed PhD students:

  • Ewan Pinnington worked with Forest Research to understand the information content in diverse observations of forest carbon stocks. The specific aim is to better define observation errors for the data assimilation problem. This was a NERC OPEN CASE award.
  • Renato Braghiere developed new representations of 3D structure for simple radiative transfer models.
  • Jennifer Price,funded by the National Centre for Earth Observation, graduated in 2015. Her thesis "Assessing the Definition of Plant Functional Types in a Dynamic Global Vegetation Model Using Earth Observation Data" uses remote sensing data to test and constrain a dynamic global vegetation model (SDGVM).

Other interests

  • I am on the Science Committee of the JULES land surface model.
  • Some years I am an instructor on the Flux Course summer school, which has been held at Niwot Ridge Colorado since 2007. This is an intensive, PhD/PDRA level, 2 week course focused on measuring and modelling carbon fluxes from forests.
  • Various software packages are available on GitHub. This includes extensive two-stream vegetation canopy and leaf geometry Python modules.
  • Code for my 2016 paper on Bayesian uncertainty in land cover data is available here. The paper is open access https://doi.org/10.3390/rs8040314 (see also publications list).
  • I have written, and maintain, software for accessing MODIS data using the SOAP protocol. The Matlab version is hosted by the ORNL DAAC and a python version can be obtained by emailing me (n.b. this is not the same as the python client on the ORNL website).
