Description du jeu de données
RésuméThe SAFIRE (Service des Avions Français Instrumentés pour la Recherche en Environnement) Falcon 20 was deployed during the FENNEC SOP in June 2011 to study the atmospheric boundary layer dynamics, the radiative budget as well as dust emission and transport over the Sahara.
Strategie d'observationThe Falcon 20 performed eighteen flights from the Island of Fuerteventura (Canary Islands), fourteen of which were made over the central Sahara, for a total of 65h (see Figure 1). The Falcon 20 was equipped with the nadir pointing backscatter lidar LNG (de Villiers et al., 2010) allowing the measurement of atmospheric reflectivity at three wavelengths (355, 532 and 1064 nm) to analyze the structure and radiative characteristics of desert dust plumes. The Falcon 20 was also equipped with a dropsondes launching device, radiometers (broad-band up- and down-looking pyranometers and pyrgeometers), the radiometer CLIMAT (Legrand et al., 2000) as well as in situ PTU (pressure /temperature/humidity) and wind sensors. The Falcon consistently flew at an altitude of 11 km amsl.
