<br />SECTION VI <br /> <br />COMPUTER PROCESSED RADIOSONDE AND RADAR DATA <br /> <br />A. General <br /> <br />The purpose of this ~ction is to describe the graphic dis- <br /> <br />plays of radiosonde and radar data generated by the Data General <br /> <br />on-site computer. Equipment components used to process, display <br /> <br />and store the data are: <br /> <br />1. Computer - Data General, Nova 2/10 <br /> <br />2. storage device - Iomec, Model 2002 disk drive unit <br /> <br />3. I/O device - Teletype Model 33 printer with punched <br />paper tape printer /reader <br /> <br />4. Graphic Display - Tektronix 4010 W /CRT display <br /> <br />5. Hard Copy Printer - Tektronix 4610 attached to <br />the CRT display unit <br /> <br />6. Software - CIC developed programs written in basic <br />and machine language. The principal programs used <br />in the Muddy Road IV hail suppression and rain aug- <br />mentation program were: <br /> <br />a. Radiosonde data reduction and analysis <br /> <br />b. Radiosonde plot (Skew-T diagram) <br /> <br />c. Radar data acquisition, processing and display of <br />PPI and RHI maps. <br /> <br />d. steady-state convective cloud model with hail <br />calculations under natural and seeded conditions <br /> <br />e. . Hail model plots <br /> <br />f. Numerous other programs for use in housekeeping <br />and statistical routines are available on site. <br />Many of these are designed to assist analysts in the <br />evaluation of cloud seeding effects. <br /> <br />19 <br />
