Latest news

• October 2011: New version of radar and lidar multiple scattering code released. New features include full Fortran 90 interface, full adjoint code for retrieval algorithms using quasi-Newton minimization and efficient modelling of multiple field-of-view and HSRL lidars.
• December 2010: Our ice cloud products derived from combining the CloudSat radar and Calipso lidar have been released. The method is described in the 2010 paper by Julien Delanoe and myself
• July 2010: Ever heard of the Equitable Threat Score, probably the most widely used verification measure in meteorology? It turns out it's not equitable: read paper
• June 2010: Atmospheric radiation schemes treat the spectral variation of gaseous absorption by splitting the spectrum into a number of bands. This seems not to be necessary, opening the way for much faster codes: read paper
• April 2010: Chilbolton lidars capture the moment when volcanic ash "touched down" in southern England

Research

My research concerns clouds, radiative transfer and remote sensing with radar and lidar. I lead the Clouds Group, although we overlap heavily with the Radar Group and many of us participate in Radiation Group meetings. Please note that I am not an expert on weather modification and so will be unable to answer any queries on this topic.

Not work

A desktop ammusement I wrote for Unix/Linux, now included in several Linux distributions.	A review of Reading Curry Houses in the style of an enduring sci-fi series.	Assorted holiday snaps.
