News

2016

• August 2016: EOS have highlighted our work on how to represent 3D radiative effects into weather and climate models, just published in JGR: Part 1 (lead author Sophia Schaefer) and Part 2.
• March 2016: ECMWF model cycle 41R2 became operational: this cycle includes my changes that have improved temperatures at coastlines and improved stratospheric climate.

2015

• June 2015: Version 1.1 of the Adept automatic differentiation software library has been released. Changes since version 1.0 include OpenMP parallelization of Jacobian calculations and use of the more permissive Apache 2.0 license, allowing it to be used in proprietary software.
• February 2015: Have a look at these three papers in Early View in the Bulletin of the American Meteorological Society: Stein et al. summarises our thunderstorm work in the DYMECS project, Illingworth et al. describes the forthcoming EarthCARE satellite with an example from my synergy algorithm, and Wood et al. describes the 2009-2010 ARM deployment in the Azores.
• January 2015: The software license of my radar and lidar multiple scattering model has been changed to Apache 2.0, which places fewer restrictions on the user.
• January 2015: Very well done also to another of my PhD students, Mark Fielding, who successfully defended his thesis on 13 January and has already published two papers.

Research

My research concerns radiative transfer, clouds and remote sensing with radar and lidar. Since April 2014 my primary affiliation is ECMWF, where I have responsibility for the radiation scheme. My past and present University of Reading activities are described on the Clouds Group web page, and I co-supervise three PhD students with Christine Chiu. I have close research links with colleages in the Radar Group and the Radiation Group.
