We analyzed the influence of the trajectory of air masses on the in situ measurements of aerosol properties (scattering and backscattering coefficients and scattering Ångström exponent) in Valencia (Spain) for the March 2006 to December 2009 period. The scattering (σsp) and backscattering (σbsp) coefficients were measured with a TSI 3563 integrating nephelometer. From the σsp and σbsp measurements, it is also possible to calculate the scattering Ångström exponent (αs).

The Guadalquivir valley favors the channeling of air masses from coastal areas to inland Andalusia. This paper presents a first approximation of the spatial variation along the Guadalquivir valley in some of the representative thermodynamic properties of air masses. We have selected three representative sites of its lower, middle and high course, analyzing all of them on their daily trajectories and hourly records of potential temperature, specific humidity and wind speed during the period 2000-2007.
