Improved understanding of the vertical distribution of simulated dust distribution in the Saharan Air Layer during the ICE-D field campaign with the WRF-CHEM model
(2016-01-11)
During the period of 4-27 August of 2015, the UK Ice in dust clouds experiment will take place in Cape Verde. UK_ICE-D will characterize aerosol particles and their ability to act as ice nuclei (IN) and cloud condensation ...
Observations of small ice in mixed phase clouds using and airborne SID2 Small Ice Detector
(2015-04-12)
Here we present observations of small ice crystals in mixed phase cloud systems using an aircraft mounted SID2 (Small Ice Detector 2) probe. It is likely that these small ice particles have formed through an immersion ...
Cloud characterization using a particle-counter dropsonde
(2015-04-12)
Routine meteorological data is obtained in the atmosphere using disposable radiosondes, giving temperature, pressure, humidity and wind speed. Additional measurements are obtained from dropsondes, released from research ...
Real-time detection of airborne asbestos by light scattering from magnetically re-aligned fibers
(2013-05)
Inadvertent inhalation of asbestos fibers and the subsequent development of incurable cancers is a leading cause of work-related deaths worldwide. Currently, there is no real-time in situ method for detecting airborne ...
Incidence of rough and irregular atmospheric ice particles from Small Ice Detector 3 measurements
(2013)
The knowledge of properties of ice crystals such as size, shape, concavity and roughness is critical in the context of radiative properties of ice and mixed phase clouds. Limitations of current cloud probes to measure these ...
Retrieving the size of particles with rough and complex surfaces from two-dimensional scattering patterns
(2012-12)
Scattered intensity measurement is a commonly used method for determining the size of small particles. However, it requires calibration and is subject to errors due to changes in incident irradiance or detector sensitivity. ...
Modelling diffraction by facetted particles
(2012-01-23)
A method to approximate azimuthally resolved light scattering patterns and phase functions due to diffraction and external reflection by strongly absorbing facetted particles is demonstrated for a cube and compared with ...
In-situ observations of volcanic ash clouds from the FAAM aircraft during the eruption of Eyjafjallajökull in 2010
(2012)
During April–May 2010 the UK Facility for Airborne Atmospheric Measurements (FAAM) BAe-146 aircraft flew 12 flights targeting volcanic ash clouds around the UK. The aircraft observed ash layers between altitudes of 2–8 km ...
A Miniature Airborne Particle Classifier (APC)
(2011-09-04)
The single greatest source of uncertainty in the estimates of climate sensitivity to either natural or man-made changes continues to be clouds (IPCC 2001, 2007). Much of this uncertainty arises from the lack of information ...
