Remote Measurements Of Clouds And Fog

ASPEN SYSTEMS PROPOSES AN INNOVATIVE APPARATUS FOR REMOTE MEASUREMENT OF CLOUD AND FOG PARAMETERS, SUCH AS WATER CONTENT. THIS LIDAR APPARATUS USES STATE-OF-THE-ART LASER TECHNOLOGY TO MEASURE THE PROPERTIES OF A CLOUD OR FOG (CONSTITUENT, WATER DROPLET SIZE AND CONCENTRATION) REGARDLESS OF AMBIENT LIGHT CONDITIONS (DAY OR NIGHT) OR LOCATION OF DEPLOYMENT (GROUND BASED OR AIRBORNE). THE PROPOSED LIDAR IS BASED ON STIMULATED RAMAN SCATTERING (SRS) OCCURING IN LIQUID DROPLETS, AND WE CALL IT "SRS LIDAR". UNIQUE TO THE SRS LIDAR METHOD IS THAT IT GENERATES SIGNALS SIGNIFICANTLY STRONGER THAN STATE OF THE ART LIDARS. IN ADDITION, IT IS AN EXCLUSIVE MEANS FOR THE MEASUREMENT OF THE WATER DROPLET DIMENSION AND SIZE DISTRIBUTION. THIS WILL PROVIDE SDIO AND THE US ARMED FORCES WITH AN ENHANCED CAPABILITY OF PREDICTING WEATHER CONDITIONS AND ENHANCE IMAGES ACQUIRED BY SPY SATETILES AND RECONNAISSANCE AIRCRAFT. IN PHASE I WE WILL PERFORM A LABORATORY DENONSTRATION THAT WILL PROVE THE FEASIBILITY OF THE PROPOSED CONCEPT. ACCORDINLY, AN ENSEMBLE OF WATER DROPLETS WILL BE DIAGNOSED. BASED ON THE EXPERIMENT RESULTS AND CALCULATIONS OF A MODEL, A DESIGN OF A DEPLOYABLE SRS LIDAR WILL BE MADE. A PROTOTYPE OF THE APPARATUS WILL BE ASSEMBLED AND TESTED IN PHASE II.
