News

2018

• February 2018: Our paper has appeared in GMD describing how the SPARTACUS approach can be used to compute the 3D interaction of solar radiation with vegetation canopies, including a demonstration implementation in Matlab.

2017

• October 2017: Adept version 2.0 has been released: this C++ library combines array and automatic differentiation capabilities.
• July 2017: ECMWF model cycle 43R3 became operational: this cycle includes my new radiation scheme ecRad.
• 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. I have research links with colleages in the Radar Group and the Radiation Group.

• My ECMWF homepage
• The Clouds Group
• Publications
• Presentations
• Curriculum Vitae (PDF)
• Overview of research interests

Research profiles:

• Google Scholar
• ResearcherID
• ORCHID

Some freely available research codes I have written:

• Adept automatic differentiation library
• 3D fractal cirrus model
• Radar and lidar multiple scattering model
• Variational polarimetric retrieval of rain and hail
• C and Matlab implementation of the Self-Similar Rayleigh-Gans Approximation
• Matlab implementation of the SPARTACUS 3D radiation algorithm for vegetation

The following is free as in beer but not speech:

• Offline version of ECMWF radiation scheme "ecRad"
