Period
ADRES EQUIPMENT WAS INTRODUCED CA. 1980 & USED INTO THE MID1990'S.
Canada
A CONTROL MODULE (GCM= GMD CONTROL MODULE) FOR AES' GMD (GROUND METEOROLOGY DEVICE) RADIOSONDE RECEIVING STATION 940146 - 940153. THIS CANADIAN DEVELOPED & MADE EQUIPMENT WAS USED BY THE CANADIAN METEOROLOGICAL SERVICE IN ITS RADIOSONDE FORECASTING & RESEARCH PROGRAMME. THE ADRES WAS A COMPUTER-BASED SYSTEM CAPABLE OF PROCESSING & ANALYSING INPUT METEOROLOGICAL DATA RECEIVED FROM RADIOSONDES & PRODUCING ENCODED MESSAGES FOR TRANSMISSION.
Function
A CONTROL UNIT FOR THE TRACKING ANTENNA OF A RADIOSONDE RECEIVING STATION, USED TO OPERATE THE ASSEMBLY FROM THE OPERATIONS ROOM. IT CONTAINS TIME, RANGE, AZIMUTH, & ELEVATION DISPLAYS & CONTROLS. IT ALSO FUNCTIONED AS AN INTERFACE BETWEEN THE ANTENNA & A COMPUTER.
Technical
DEVELOPED IN THE LATE 1970'S, THE ADRES REPLACED THE ELECTROMECHANICAL SYSTEM OF DATA REDUCTION PREVIOUSLY USED WITH THE GMD, A SYSTEM WHICH REQUIRED CONSIDERABLE CALCULATION. IN THE MID 1990'S THE ADRES WAS REPLACED BY A SINGLE MINI-COMPUTER. ADRES STANDS FOR AEROLOGICAL DATA REDUCTION SYSTEM. THIS RADIOSONDE GROUND SYSTEM WAS REPLACED BY THE VAISALA SYSTEM WHEN THE VIZ/VALCOM RADIOSONDES [2004.0358-.0359, 2005.0041-.0042. 2005.0044] WERE REPLACED BY THE VAISALA RS80 RADIOSONDES [1987.0926, 1991.0096, 1991.0100, 1992.0002, 1994.0140-.0141, 2004.0360, 2005.0043], MOSTLY BETWEEN 1992 AND 1994. THIS EXTERNAL CONTROLLER IS USED WHEN THE RADIOSONDE IS RELEASED TO DIRECT THE GMD ANTENNA TOWARD THE RADIOSONDE AND TO SIGNAL THE MINICOMPUTER TO START STORING THE ANTENNA ANGLES WHICH ARE USED TO COMPUTE THE UPPER WINDS (REF. 4).
