History

UPDATE2017-06-06
In V0 we did not included good-quality wind-data because of one pending wind-tunnel calibration. More reliable wind-data is now included in the newest V2. As an addition, there is an extra file of each record (called *_additional.nc) including black carbon measurements and some low-rate sensor raw-data.

Description du jeu de données
RésuméThe aircraft ALADINA is equipped with meteorological sensors for observing temperature (slow and fast sensor available), humidity (two different sensors available) and the wind speed vector (calculated from the flow angles alpha and beta of a five-hole probe, together with dynamic pressure and attitude). Further, an upward and a downward looking pyranometer are available. The data can be used to estimate cloud coverage, but cannot be used as absolutely calibrated values. Additionally, time, latitude, longitude, altitude and attitude of the aircraft are available. The data are provided for each of the records separately. A document providing the time sections for the different parts of the flight (vertical profiles, straight legs) is additionally included.
Strategie d'observationThe typical flight of around 30 to 40 min duration consisted of at least one vertical profile up to 1000 m (in case of low clouds: directly below the cloud base) and a star pattern with straight legs of at least 1 km length at constant altitude, with several altitudes for each flight.
