Ian Strangeways obtained his first degree in electronic engineering, physics and maths from Bangor University, followed by a PhD in meteorological instrumentation from Reading University. After 24 years at the Institute of Hydrology, where he was head of Applied Physics, concerned with measuring the hydrometeorological environment, he became Director of TerraData, a consultancy in meteorological and hydrological data collection. He has written three books - Measuring the Natural Environment, now in its second edition (Cambridge University Press 2003), Precipitation; Theory, Measurement and Distribution (Cambridge University Press 2007) and just recently Measuring Global Temperatures: Their Analysis and Interpretation (Cambridge University Press 2010). He has also written many papers on the topic of data collection, climate measurement and instrumentation and has written extensively for the Royal Meteorological Society’s (RMetS) magazine Weather for which he received the Gordon Manley Award in 2005. He is on the committee of the RMetS Special Interest Group on Meteorological Observing Systems, which he also chaired for three years. He has travelled extensively to many remote parts of the world advising on the monitoring of the weather, rivers, water resources and flooding. He has given talks at major national and international conferences and has been an external lecturer on the subject at Newcastle University and the Open University as well as instructing students overseas. He is a Fellow of the RMetS and an Associated Member of the British Hydrological Society and the Institution of Civil Engineers. Currently he is researching the uncertainties in climate science.
