PROJECT INFO: DLR ECLIF3 Q2 2021 aircraft campaign; 09 April - 19 April 2021; Oberpfaffenhofen / Germany
FLIGHT NUMBER: Q2 #02
First version of data (V1)
The dataset is reduced to only include far field encounters with valid ice measurements at relative humidity over ice above 100% and at stable engine conditions and for AEI uncertainties smaller than 100%.
The dataset was further reduced to only include encounters where ice particle number concentration and CO2 concentration correlate more than 60%.
Delta_z is calculated by subtracting Falcon GPS altitude at time of detection by Airbus GPS altitude at time of emission. Therefore negative values indicate detection below emission altitude and positive values indicate detection above emission altitude.
Inform the PI (Christiane.Voigt@dlr.de) on intended data use and publication.
