Dr Rick Thomas is a innovative measurement scientist specializing in the use of novel instrumentation for climate and air quality research. He launched Big Sky Science Ltd (named after the inspirational skies of his Lincolnshire birthplace) to help provide practical solutions to urgent local and global environmental issues.
His background includes work at Scripps Institution of Oceanography in California, where he developed a turbulent flux measurement package to resolve ambient 3D wind vectors from an unmanned aerial vehicle (UAV) and successfully used it alongside aerosol, cloud and water probes to investigate aerosol-cloud-climate interactions. Including flying up to 14,000ft in altitude and 100 nautical miles horizontally in the Indian Ocean.
He has developed many other instruments, including recently i) a gas sampling device for a UAV helicopter platform used to obtain isotopic methane information from 9,000ft above the southern Atlantic Ocean and ii) lightweight meteorological sensors comfortably carried by racing pigeons to measure fine-scale microclimate variability above urban areas. His PhD was in earth atmosphere exchange of trace gases and particulates using turbulent flux measurement techniques.
Rick has also led five iterations of a hands-on summer school to disseminate all aspects of drone use for the environmental sciences.
