The Aethalometer calibration and determination of iron concentration in dust aerosols
This paper shows the use of the instrumental neutron activation analysis (INAA) technique to calibrate Aethalometer instruments’ response to iron oxides present in Saharan dust aerosol. The five samples selected for this calibration were collected with a seven-wavelength Aethalometer (model AE31) at...

| description | This paper shows the use of the instrumental neutron activation analysis (INAA) technique to calibrate Aethalometer instruments’ response to iron oxides present in Saharan dust aerosol. The five samples selected for this calibration were collected with a seven-wavelength Aethalometer (model AE31) at the summit of Pico mountain (2225
m ASL) in the Azores Islands. These samples correspond to measurements taken between the 31 October and 5 November, 2001. Analysis of these samples by the INAA technique gave a total mass of
