Calder, Ian R.
Ian Rainy Calder - 14 May 2009 (UK)
Professor Ian Calder was Director of the Centre for Land Use and Water Resources Research at Newcastle University, UK, and Coordinator of the IUFRO Task Force on Forest and Water Interactions. Ian Calder was a specialist in forest hydrology, land use and integrated water resources management. He held a BSc in Physics and special maths, and a PhD in Cosmic Ray Physics (Leeds University). For many years he worked at the Insttiute of Hydrology in the UK before taking up the post in Newcastle. He was a member of the Global Forest Expert Panel on Adaptation of Forest to Climate change coordinated by IUFRO.
Ian Calder made significant contributions to the study and modelling of interception and evapotranspiration by tree canopies, including novel instrumentation such as the use of large sheets for collecting throughfall, a large natural lysimeter at Plynlimon, and gamma rays for measuring interception storage. He was one of the first people to use stochastic models of interception by trees. While at the Institute of Hydrology he carried out major studies at Plynlimon, Wales, and in India, Malawi, and Java. An important modelling paper (Calder et al., 1985) showed that even simple soil moisture deficit models could reproduce observed soil moisture deficit rather well, even under rather extreme conditions. Adding model complexity added little or no predictive power.
