    • Cloud Ice Properties: In Situ Measurement Challenges 

      Baumgardner, Darrel; Abel, Steve; Axisa, Duncan; Cotton, Richard; Crosier, Jonathan; Field, P.R.; Gurganus, Colin; Heymsfield, Andrew J.; Korolev, Alexei; Kraemer, Martina; Lawson, Paul; McFarquhar, Greg; Ulanowski, Zbigniew; Um, Junshik (2017-04-10)
      Understanding the formation and evolution of ice in clouds requires detailed information on the size, shape, mass and optical properties of individual cloud hydrometeors and their bulk properties over a broad range of ...

    • The effective density of small ice particles obtained from in situ aircraft observations of mid-latitude cirrus 

      Cotton, Richard; Field, P.R.; Ulanowski, Joseph; Kaye, Paul H.; Hirst, Edwin; Greenaway, Richard; Crawford, I.A.; Crosier, J.; Dorsey, James (2013-10)
      The effective ice-particle density, parametrized through a mass–dimension relation, is widely used in ice microphysical schemes for weather and climate models. In this study, we use aircraft-based observations in mid-latitude ...

    • In-situ observations of volcanic ash clouds from the FAAM aircraft during the eruption of Eyjafjallajökull in 2010 

      Johnson, Ben; Turnbull, Kate; Brown, Phil; Burgess, Rachel; Dorsey, James; Baran, Anthony J.; Webster, Helen; Haywood, Jim; Cotton, Richard; Ulanowski, Zbigniew; Hesse, Evelyn; Wolley, Alan; Rosenberg, Philip (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 ...

    • Rough and irregular ice crystals in mid-latitude clouds
