In-situ and remote measurements made on the Airborne Research Australia (ARA) Grob Egrett T520 Aircraft for the CWVC EMERALD-2 Campaign based in Darwin, Australia, during November and December 2002

The dataset contains aircraft position information plus Cloud Particle Imager and Forward Scattering Spectrometer Probe (CPI-FSSP)(University of Manchester Institute of Science and Technology -UMIST) to measure cloud microphysical properties, turbulence and temperature probes (Aberystwyth/ARA), Tropospheric Airborne Fourier Transform Spectrometer (TAFTS) (Imperial College) which is a far infra-red spectrometer, an ozone monitor and frost point hygrometer (Aberystwyth/DLR-Deutsches Zentrum für Luft- und Raumfahrt - the German Aerospace Center) and a water vapour Tunable Diode Laser analyzer (TDL)(Aberystwyth)

The EMERALD projects were airborne measurement campaigns designed to study dynamical, microphysical and infra-red radiative properties of cirrus clouds, using both in-situ and remote measurement techniques. The ARA Grob Egrett T520 aircraft which flew above the cirrus clouds looking down in conjunction with the ARA King Air aircraft below looking up.

These data are part of the NERC Clouds, Water Vapour and Climate (CWVC) programme.
