Since 2002 I have worked for The Met Office Hadley Centre as a climate scientist.
Mostly I have been collecting and analysing weather observations from the last 250 years - making long, homogenous records of surface weather, which can be used to quantify recent climate changes and to put them in context. This has lead to new historical analyses of sea-surface, land surface, and upper-air temperatures, and surface pressure patterns. I've also been looking at proxy weather data (tree-rings, corals, and pollen samples) from longer ago, and comparing them to climate model simulations.
I'm also interested in using observations and proxy data to validate Climate Models and constrain model-based predictions of future climate.
