Development of Atmospheric Monitoring System for Auger North

The Pierre Auger Northern Fluorescence Detector will measure air-showers over distances of 40 km. Vertical Aerosol profile of the atmosphere at the Pierre Auger Northern site will be measured using the side-scatter method over the 40 km baseline. An atmospheric monitoring telescope (AMT) will use a 3.5 m$^2$ mirror optimized for UV reflection to focus light from a laser onto a cluster of phototmultiplier tubes. The AMT has been built and final testing and modifications are being carried out before its installation later this year. A remotely programmed, 355 nm YAG laser with a final beam energy of 5 mJ is being used. The automation of the laser and the AMT is controlled via a single board computer (SBC). This talk will present an overview of this R\&D program.
