What role does convection play in cloud feedbacks within a changing climate? What role does the self-organization of convective clouds play in the climate system? The NARVAL-II campaign contributes to answer these key questions in climate science by targeted observations of trade wind convection in the vicinity of Barbados.

For this purpose, the German research aircraft HALO was equipped with a comprehensive suite of cloud remote sensing instruments:

  • a cloud radar detected the vertical cloud structure,
  • microwave radiometers allowed quantitative estimates of water content in all phases,
  • sensors in the solar frequency range detected cloud geometry and the types of hydrometeors.

HALO was stationed at Barbados in August/September 2016 for three weeks and flew research missions for about 95 hours in total. The measurements and derived data products are provided to the scientific community via the HALO data base. NARVAL-II observations complemented the data record obtained during the NARVAL-I campaign in winter 2013/14 and the measurements during the NAWDEX campaign, which took place in September /October 2016 over the high North Atlantic.
