Dr John Marsham's Homepage

I am a water@leeds Academic Research Fellow (Associate Professor), working on moist convection and precipitation within the National Centre for Atmospheric Science (NCAS-Weather) and the Institute for Climate and Atmospheric Science (ICAS), in the School of Earth and Environment (SEE) at the University of Leeds.

Research Interests

My research is focused on atmospheric convection and its role in weather, climate and the earth-system (particularly dust uplift). I was awarded the Royal Meteorological Society's L F Richardson prize in 2009 and the European Meteorological Society's Young Scientist Award in 2010. I am a member of Africa College and Water@Leeds.

My publication list is available (via Google Scholar).

Postgraduate Teaching

I used to teach an introductory IDL course for postgraduates. This was to some extent based on Hugh Pumphrey's (University of Edinburgh) IDL course. Notes are available (note icons at top left that step forward/back through these). Data used in the course are available (please note that is still work in progress).

Although these notes are a step-by-step introduction, I would also encourage people to look at the numerous examples in Andy Heap's (Centre for Global Atmospheric Modelling, The University of Reading) An Introduction to Using IDL in Meteorology. --- these notes contain some more sophisticated examples and also a good summary. There is also an online preview of IDL programming techniques available, as well as paper books (such as Practical IDL Programming by Liam Gumley). It's also worth looking at David Fanning's site , e.g. his slow-loops tutorial. If you do atmospheric science, Dominik Brunner's Basic IDL routines for atmospheric science are really useful. Once you think that you've really got IDL sorted you could always join the IEPA !

None of these notes really cover good and bad practise in scientific programming. For that you might want to consult Jason Lander's notes on How not to write a computer program.
