The IASI instrument was launched on the Metop satellite in October 2006. (Delayed from April 2006). Eumetsat is providing funds for the BAe146 to be involved in validation of IASI radiative transfer and some level 2 products.
Flights will be flown over oceans to coincide with METOP satellite overpasses. Further flights will be flown low level over specific land calibration sites to characterise land surface emissivity. There may also be co-incident flights with other platforms including US ER-2 or Proteus aircraft and French high altitude balloon.

Land Emiss aims to study the thermal infrared emissivity of a range of different land surface types. A UK based camapaign will be flown in the May-June 2006 period. In addition the possibility of including Land Emiss sorties during the DABEX and/or T-REX foreign detachments will be pursued.
A further period of UK-based flying is expected for summer 2007 and opportunities for flights over snow and ice will be investigated.

The overall aim of RICO is to improve the characterization of trade-wind cumulus clouds at all scales. Such clouds are very common over large region of the tropical oceans and therefore play a key role in the global energy balance. Since they are confined below the freezing level, they are dominated by warm-rain microphysical processes. A key detail aim is therefore to determine the dominant processes responsible for the rapid onset of precipitation, the candidates being turbulent or entrainment-related droplet spectral broadening, mixing between growing and dissipating clouds, cloud processing of CCN aerosol and ultra-giant nuclei. In-situ measurements of loud updraught strength, width and buoyancy excess will contribute to the validation of parametrization schemes for shallow convection. Boundary-layer and mesoscale processes that determine the spatial and temporal organization of the clouds will also be studied.
The experiment will be based on an island in Antigua. The requirement is to have a ground site from where radars can view the clouds well out over the ocean in easterly flows undisturbed by any land. A number of other aircraft may also participate, including the NCAR C-130 and Univ. of Wyoming King Air, together with a research vessel. Optimum conditions are expected to occur in December and January, with an absence of deep convection in the operating region. Two aircraft IOPs are proposed, either side of Christmas 2004.

The goal of this research is to understand and quantify the formation and growth of ice particles in cumulus congestus clouds. We aim to do this by making measurements in cumulus congestus clouds with the BAE 146 aircraft when possible in the vicinity of the dual-polarisation Doppler radar at Chilbolton. Key instruments have recently been developed that will significantly improve our ability to detect and observe the number concentration, size and shape of small ice crystals. Together they provide a suite of very sophisticated equipment for investigating the origins and development of the ice phase in supercooled clouds.
The campaign will be run in collaboration with the Convective Storm Initiation Project.

Based at Keflavik, Iceland. Feb 2007.

Objectives:

  • Improve our understanding and ability to predict interactions between the atmospheric circulation and the topography of Greenland, both locally and downstream over Western Europe.
  • Obtain hitherto rare in situ observations of high-impact weather systems and their associated air-sea fluxes in the coastal seas of Greenland.
  • Improve the numerical modelling and prediction of these weather systems, testing (for example) the boundary-layer and turbulence parameterisations, and thus improving the quality of the atmospheric forcing fields that are essential for accurate atmosphere-ocean coupling and the thermohaline circulation.
  • Improve the numerical modelling and prediction of high-impact weather systems over Europe through the use of targeted observations upstream in sensitive areas of the flow.
