General <br /> <br />The purpose of this section 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 in Muddy Road IV <br /> <br />and V to process, display 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 <br />punched 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 <br />basic and machine language. The principal pro- <br />grams used in the Muddy Road hail suppression <br />and rain augmentation programs were: <br /> <br />a. Radiosonde data ~eduction and analysis <br /> <br />b. Radiosonde plot (Skew-T diagram) <br /> <br />c. ' Radar data acquisition, -processing -and 'dis- <br />play of PPI and RHI maps <br /> <br />d. Steady-state convective cloud model with <br />hail calculations under natural and seeded <br />conditions <br /> <br />e. Hail model plots <br /> <br />f. Numerous other programs for use in house- <br />keeping and statistical routines are available <br />on site. Many of these are designed to assist <br />analysts in the evaluation of cloud seeding <br />effects. <br /> <br />18 <br />
