Falcon measurement campaigns
The first PAZI related flight missions were conducted with the DLR Falcon in Jan/Feb 2005 as part of the TROCCINOX 2005 campaign in Aracatuba in the state of Sao Paulo, Brazil. Further information about TROCCINOX can be found on the TROCCINOX homepage.
Measurement focus and main scientific questions
- Measurements of H2O with emphasis in and near ice supersaturated regions
- Intercomparison of TDL and hygrometer instruments, including TDL validation
- How is water partitioned between gas phase and ice phase ?
- Can we confirm the relationships between vertical wind, relative humidity, and total ice crystal concentration known from previous measurements ?
- Measurements of aerosol and cirrus cloud properties
- Extend and complement original TROCCINOX goals for subvisible clouds
- How do aerosols grow and freeze in ice supersaturated air and can we establish a quantitative link to ice cloud properties?
- What are the relationships between ozone, NOy, lightning, and clouds ?
- Measurements of SO2 and nucleation mode particles
- Validation of global model predictions of tropical and subtropical SO2 and NOy concentrations
- How is SO2 transported in convection, in anvil outflow, and above convective cloud tops and can we quantify its abundance?
- Is new aerosol particle formation in clear air linked to SO2 and does it also occur within or nearby cirrus clouds ?
During the merged TROCCINOX-PAZI campaign Jan/Feb 2005 in Brazil the Falcon made six local flights with an enhanced in situ instrumentation onboard, and six further local flights with lidar/in situ instrument combination.
Data of these flights are included in the TROCCINOX data base (password protected). Analysis of data is ongoing.
