COMPLETED RESEARCH PROJECTS

Observational research projects are rarely 'finished' - the data sets are still valuable and analysis and modelling studies associated with them may continue for years, sometimes decades. The grants, however, do run out, and the formal projects. These are some projects for which the funding has ended...we're still working with the data.

SO-SAFE : Southern Ocean Sea-spray Aerosol Flux Experiment
A joint project with Will Drennan at the University of Miami - a CLASP aerosol probe was installed on Miami's Air-Sea Interaction Spar (ASIS) buoy to measure sea-spray aerosol fluxes as part of a major US field project - the Southern Ocean Gas Exchange Experiment (SO-GASEX or GASEX-III) - which took place during March-April 2008.

Balloon validation of remotely sensed aerosol properties
Based at the Chilbolton Observatory, this project aims to test new lidar retrievals of aerosol properties. A group from Leeds led by Dr Barbara Brooks made in-situ measurements of boundary layer structure and aerosol spectra using instruments carried by a tethered balloon during a month-long field campaign in April 2008. These measurements are being used to develop and test remote sensing retrievals of aerosol properties made using the multiple lidars installed at Chilbolton. Ulitimately the results of this study will be applied to satellite-based lidars to provide global information on atmospheric aerosol properties. Additional measurements of turbulence are being used to validate doppler lidar estimates of turbulence dissipation rate. The study is a joint project with Prof. Anthony Illingworth and Dr Ewan O'Connor at Reading University.

SEASAW : Field Observations of SEA Spray, Gas Fluxes, And Whitecaps
A SOLAS project to study surface exchange processes, particularly of CO2, and the production of sea-salt aerosol under high wind conditions. Two cruises on the RRS Discovery were undertaken: D313 (November-December 2006) and D317 (March-April 2007).

Atmosphere-Canopy Interactions over Complex Terrain: a field-based study of the effects of turbulent drag on atmospheric flow over forested hills, led by Dr Andy Ross.
