| Description du jeu de données | |||
| Résumé | The Photomètre Léger Aéroporté pour la surveillance des Masses d’Air (PLASMA, Karol et al., 2013) is an airborne Sun-photometer developped at Laboratoire d'Optique Atmosphérique (LOA, Lille, France). PLASMA2 operated from the SAFIRE Falcon 20 during AEROCLO-sA campaign. | ||
| Strategie d'observation | PLASMA2 is a sun-tracking photometer providing aerosol optical depths over a wide spectral range (from 340 to 1640 nm). | ||

| Instrument features / Calibration | PLASMA2 data have been pre- and post-calibrated with AERONET master Sun-photometers. The instrument has also been tested in a controlled chamber (CHARME, CHamber for Atmospheric Reactivity and Metrology of the Environment) thanks to Cécile Coeur. | ||

| Instrument environment | The aircraft was equipped with active and passive remote sensors as well as in situ probes to document aerosol optical and radiative properties over land and over maritime stratocumulus clouds. In addition to PLASMA2, the Falcon 20 also housed the LNG instrument measuring the atmospheric reflectivity at 3 wavelengths: 355, 532 and 1064 nm. The imager OSIRIS (3MI airborne prototype) allows to measure total and polarised radiances from UV to SWIR. A dropsonde releasing system, up‐ and down‐looking pyranometers and pyrgeometers, a nadir‐facing CLIMAT infrared radiometer, together with pressure, temperature, humidity and wind sensors, and optical sensors for cloud and aerosol microphysics completed the instrumental suite of the Falcon 20. | ||
