Hello,

There is a PhD studentship available at the University
of Exeter (UK), on ground-based and airborne remote sensing
techniques for the estimate of volcanic ash plumes.

NERC GW4+ DTP PhD studentship: Developing Resilience to
Icelandic Volcanic Eruptions (DRIVE).

University of Exeter

The Met Office Volcanic Ash Advisory Centre (VAAC) is responsible for providing 
forecasts of volcanic ash from Icelandic volcanoes and has established a new 
network of ten ground-based lidar/sunphotometer sites across the UK providing 
independent estimates of the mass concentration of volcanic ash. This network 
uses a combination of particle size distribution and aerosol optical depth 
measurements derived from sun-photometers with lidar retrievals of aerosol 
vertical distribution and depolarisation to estimate the aerosol concentration. 
These novel retrievals are associated with considerable uncertainties 
associated with implicit assumptions. The Met Office is also resourced with the 
Met Office Civil Contingency Aircraft (MOCCA; 
http://www.metoffice.gov.uk/publicsector/emergencies/civil_contingency_aircraft)
 equipped with a lidar and in-situ instrumentation for sampling aerosols.
DRIVE will have unique access to data from these facilities and will use 
in-situ observations to assess the accuracy of the lidar and sun-photometer 
remote sensing retrievals. It will utilise the relatively frequent occurrence 
(6-8 events per year) of mineral dust events over the UK, as mineral dust has 
proved a good proxy for volcanic ash in terms of size distribution, density, 
non-sphericity and composition.
