News

2017

• February 2017: ECRAD, the offline version of the new ECMWF radiation scheme is now available under the OpenIFS license.

2016

• December 2016: I have extended the Self Similar Rayleigh Gans Approximation (SSRGA) to compute the full scattering phase function of snow aggregates observed in the microwave (Hogan et al., QJ). C and Matlab implementations of the algorithm are available on the SSRGA page.
• 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.

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.
