Low-volume sampling on weekly filters is operated since 2002 at PDM. The aerosol-laden air is conducted through two distinct sampling lines towards specific filters. The air sampling volume is about 400 m3 per week. Each filter integrates the whole weekly air volume. Filter specificitions are motivated by the post analysis: The filter dedicated to the […]
The TSI model 3750 Condensation Particle Counter is an instrument that detects airborne particles down to 7 nanometers in diameter at an aerosol flow rate of 1.0 liter per minute, over a concentration range of 0-100 000 #/cm3.The aerosol sample is drawn continuously through a heated saturator in which butanol is vaporized and diffuses into […]
The Optical Particle Sizer performs measurements of the size distribution of aerosols samplings between 0.8 µm and 10 µm. This part of the size distribution of aerosols is measured continuously and gives information mainly for the coarse mode. L2B data available under ACTRIS framework at https://ebas.nilu.no/data-access/ (research key “Pic du Midi”).
The Ecotech Aurora 3000 nephelometer simultaneously measures at 450 nm (blue), 525 nm (green) and 635 nm (red) to enable analysis of the interaction between light and aerosols. The nephelometer includes measurements that allow both standard integrating scattering measurements of 9 – 170° and also the backscatter 90 – 170°. Scattering and back scattering properties […]
(Filter absorption photometer) The aethalometer Magee Scientific AE33 enables to perform continuous measurements of aerosol Black Carbon (mostly named eqBC for equivalent Black Carbon, as the principle of measurement is based on optical attenuation). The aerosol-laden air stream is drawn through a spot on a filter tape at a measured flow rate. Simultaneously, the tape […]

This instrument is part of the French national observation service SNO NDACC-FR and the international network NDACC. Data access: https://ndacc-aeris.ipsl.fr/#/stations/LZA https://ndacc.larc.nasa.gov/stations/lannemezan-france Le spectrophotomètre de Dobson doit son nom au chercheur de l’Université d’Oxford, G. M. B. Dobson qui, vers 1920, fut l’un des premiers à s’intéresser à l’ozone atmosphérique. Cet instrument mesure la quantité totale […]
Modèle Rupprecht & Patashnick TEOM 1400ab La mesure des particules est réalisée par une micro-balance oscillante. La taille des particules prélevées est limitée par une tête de coupure à 10 µm (PM10). Une tête de coupure à 2.5 µm (PM 2.5) est également disponible. L’échantillon est ensuite prélevé sur un filtre conique dont la fréquence […]
