Dr. Timmy Francis

Profile

Timmy’s current research focusses on Perturbed Parameter Ensemble (PPE) modelling with the UKESM and UKCA models, which combined with Gaussian Process emulators will be used to quantify the magnitude and causes of uncertainty in marine sulfur gases and aerosols. His previous project at the university of Leeds focused on the climatic implications of future low carbon aviation, employing the UK Met Office Unified Model (UM) with a new contrail module. He has many years’ experience working with UM in various configurations (global, high resolution nests) as well as the UK Chemistry Aerosol (UKCA) model, on High Performance Computing facilities.

His previous research experiences include: operational fog/visibility forecast employing UKCA in high resolution (330m) nested configuration (Urban Modelling), Radiative forcing studies employing UM (nested, 1.5 km grid length) via double radiation call approach, Convection permitting model (UM-Regional, 4km) simulations of Mesoscale Convective Systems, CFMIP Observation Simulator (Satellite Simulator) Package (COSP) in UM (Global), Chemical transport modelling using GEOS-Chem and so on. He also worked extensively in the field measurements of aerosols and trace gases and their chemical analysis in laboratory. He developed an interest in paleoclimate as well, with stable isotopic studies on speleothems for Indian Sumer Monsoon reconstruction, luminescence dating of sand dunes, lake sediments etc. He also has experience simulating high energy particle – matter interactions using GEANT4.
