Role

Tom Gardiner

Tom Gardiner is a Principal Research Scientist at NPL and he leads atmospheric science research within the environmental measurements science area. In addition to his role at NPL, Tom sits on the steering group for the Global Climate Observing System (GCOS) Reference Upper-Air Network (GRUAN).

Current interests

Tom has over twenty years' experience with NPL. He is a specialist in the development and implementation of advanced trace gas monitoring techniques, and the assessment of the calibration requirements and uncertainty analysis of such measurement techniques. He has internationally leading expertise in the development of the complex optical systems required for Differential Adsorption Lidar (DIAL) and he leads research with universities to develop new laser sources for atmospheric sensing.

Biography

Tom has a first class honours degree (BSc) in Physics from the University of Birmingham.

Tom's work on advanced trace gas monitoring techniques has included the development of new laser-based techniques for remote sensing systems, including a novel injection-seeded optical parametric oscillator, and a near-infrared tuneable diode laser spectrometer.

His experience with Fourier Transform Spectrometers includes use of a high resolution instrument as a mobile transfer standard for the Network for the Detection of Atmospheric Compositional Change (NDACC); leading NPL's involvement in a European project investigating the use of FTIRs for remote profile measurements in the troposphere; and the development of a radiatively-calibrated FTIR facility for absolute measurements of solar absorption in the atmosphere. He has extensive field measurement campaign experience. These campaigns have included ground-based measurements involving a Fourier Transform Spectrometer and a Laser Heterodyne Spectrometer, and balloon- and aircraft-based measurements with a tuneable diode laser absorption spectrometer.

Tom also has over eighteen years' experience in DIAL measurements. This has included operation and management of the system on measurement campaigns at petrochemical refineries and storage facilities, chemical works, landfill sites, coking plants and retail gasoline filling stations, as well as developing new non-linear optical sources for infrared DIAL measurements.
