CADDIWA-2021 : Cloud in situ 1Hz data from CDP probe

The CDP cloud microphysics dataset contains in situ measurements collected during CADDIWA field campaign along the SAFIRE F20 flight track with a Cloud Droplet Probe (CDP).
The CDP (from the PMA plateform) was installed on a pod underneath the F20 starboard wing (inner position). The CDP is a cloud particle spectrometer that counts and sizes cloud droplets in the 2-50 micrometer range into 30 size classes with a resolution of 1 to 2 µm. The raw data (counts per second) is processed using DMT built-in sizing & counting algorithms. The probe sample volume is calculated using the true TAS (from F20 Core measurement dataset) and calibrated sample area.

Data acquisition was synchronized with the F20 GPS clock and the data is geolocalized using aircraft position. The dataset contains one file per flight, 8 files in total (1).

(1) : Due to a technical issue (laser diode failure) at the end of flight #7 (2021/09/11 AM), no CDP data are available for flight #8 (2021/09/11 PM). The data from flight #9 to #13 are taken with a spare instrument (CDP v1) installed on the F20 after flight #8.
