Aerosol optical characteristics at BTN station
Entry ID: Aerosol_opt_char_at_BTN_station

Abstract: Measurements performed at BTN (Icaro Camp) in the austral summer 2001 - 2002
with the PREDE POM 01L sun-photometer. It detects direct solar radiative flux
as well as diffuse at selected scattering angles and at six wavelengths.
Aerosol optical characteristics were derived making use of Nakajima inversion
code SKYRAD. Aerosol optical depth was evaluated at 6 channels centered at 315,
400, 500, 870, 940, 1020 nm wavelength bands. The sampling time interval is
about 15 minutes. The air mass is also given. Data were collected under
cloudless-sky conditions. An in situ radiometer calibration is also performed
by means of a modified Langley plot.
