ACRIDICON-CHUVA
Sept. - Oct. 2014, Manaus, Brazil
Aerosol, Cloud, Precipitation, and Radiation Interaction and Dynamics of CONvective Cloud Systems - Cloud Processes of the Main Precipitation Systems in Brazil: A Contribution to Cloud Resolving Modeling and to the GPM (Global Precipitation Measurement)
To obtain a better understanding of the interaction of aerosols, clouds and radiation in convective clouds, simultaneous measurements of all aspects is desireable. To this end, the ACRIDICON-CHUVA campaign was conducted in September 2014 with the German research aircraft HALO. During the same period, the CHUVA project obtained a multitude of ground-based measurements. In addition, the ARM Aerial Facility (AAF) Gulfstream-1 (G-1) was deployed simultaneously to the Amazon to obtain measurements of cloud, trace gas, and aerosol properties.
The HALO integration phase took place in Oberpfaffenhofen during July/August 2014. Despite several unexpected bureaucratic problems, several test flights were conducted to ensure that all instruments worked properly and to train the operators. The measurement phase at Manaus (Brazil) started with the ferry flights (via the Capverdes) on September 01 and 02, 2014. These ferry flights were already used as measurement flights. At Manaus, we conducted 14 scientific flights between Sept. 06 and Oct. 01, before returning to Germany with two ferry flights, again via the Capeverdes, on Oct. 03 and 04.
