Lasers shine light on climate change

A

(UH) team is developing an advanced laser-based instrument to help research into climate change for an atmospheric research aircraft.

Professor Paul Kaye, Dr Edwin Hirst and Dr Richard Greenaway at UH’s Science and Technology Research Institute (STRI) have been commissioned by the US University Corporation for Atmospheric Research (UCAR) to build the instrument for their new HIAPER (High-performance Instrumented Airborne Platform for Environmental Research) aircraft, based in Colorado.

The instrument, which is being tailored to UCAR’s requirements, will be used to study microscopic water droplets and ice crystals in clouds, providing information to meteorologists to help them to make climate prediction models more accurate.

Professor Kaye said, "We had already developed instruments for the Met Office and other researchers in the UK to help them understand some of the processes that take place in clouds and how these ultimately affect our climate and potential global warming. UCAR scientists became aware of this work and asked us to design and build a new instrument for their use. It’s a significant step for us because the HIAPER aircraft is a very exciting development to be contributing to."
