SURVEILLANCE OF WATER QUALITY

AERIAL THERMAL-INFRARED SENSING WAS ADDED TO THE NEW YORK STATE WATER-QUALITY SURVEILLANCE PROGRAM IN 1970 THROUGH COOPERATION WITH THE U. S. GEOLOGICAL SURVEY. BECAUSE THERMAL RADIANCE CAN BE USED AS A NATURAL TRACER OF WATER CIRCULATION, IT IS USEFUL IN VERIFYING THE VALIDITY OF POINT-SAMPLE LOCATIONS AND HYDRODYNAMIC MODELS. MEASUREMENTS ARE NEEDED FOR ARCHIVAL THERMAL RECORDS. AIRBORNE EQUIPMENT CONSISTED OF A FIXED-FIELD RADIOMETER, LINE-SCANNER WITH THERMAL REFERENCES, A. C. AND D. C. AMPLIFIERS, TAPE RECORDER, DISPLAY SCREEN, AND FILM PRINTER. CORRELATIVE INFORMATION INCLUDED WEATHER DATA AND WATER-TEMPERATURE RECORDS FROM THE STATE AUTOMATIC WATER-QUALITY NETWORK AND OTHER SOURCES. DATA COLLECTION WAS MONITORED IN FLIGHT SO THAT PROPER AERIAL AND THERMAL DATA WOULD BE OBTAINED. THE QUANTITATIVE DATA PERMITTED OBSERVATION OF LOCAL WATER-HEAT BUDGETS. THERMAL-INFRARED IMAGERY IS USEFUL TO WATER MANAGERS IF IT IS CALIBRATED SO THAT REGIONAL INTERPOLATIONS BETWEEN EXISTING POINT MEASUREMENTS CAN BE MADE. IN ADDITION, THE PICTORIAL FORMAT CAN PRESENT DATA IN AN EXPEDIENT MANNER TO WATER PLANNERS, MANAGERS, AND USER. /AUTHOR/
