VAP : Aerosol Intensive Properties (AIP)

Instrument Categories

The aip1ogren value-added product (VAP) computes several aerosol intensive properties. It requires as input calibrated, corrected, aerosol extensive properties from the Aerosol Observing Station (AOS). Aerosol extensive properties depend on both the nature of the aerosol and the
amount of the aerosol. Intensive properties are independent of aerosol amount, depending only on the nature of the specific aerosol. The intensive properties of hygroscopic growth factor, aerosol single-scattering albedo, hemispheric backscatter fraction and angstrom exponent are produced at a one minute sample rate. The submicron scattering and absorption fraction are produced on an hourly sample rate.
