In the frame of the first research cooperation project between the Optics Atmospheric Group of the University of Valladolid, Spain and the Camagüey Lidar Station entitled “Study of the optical properties of the tropospheric aerosols at Camagüey, Cuba”, two instruments have been installed at CLS for aerosols monitoring in the eastern part of Cuba.

The first instrument is a cascade particle impactor for studying the particulate matter at the surface according to the PM10 and PM1 standards.  The instrument is a DEKATI PM10 and is operative from February 7th 2008.

The second instrument already installed as part of the project is a sun photometer CIMEL model CE-138 with six interferential filters at the wavelengths of , 500, 670, 870, 1020 y 1640 nm.  The instrument is designed for conducted very precise measurements of solar direct and diffuse radiation.  It operates autonomously tracking the sun during the day and conducting several types of measurements.  The installation of the instrument began on September 24th 2008 and it became operative on October 9th 2008 at 18:43 GMT.
