<br />2.4 Satellite Data <br /> <br />Geosynchronous satellite imagery was obtained in the field in real- <br />time using a Geosynchronous Operational Environmental Satellite (GOES) <br />telephone line between the NWS, WSFO at Lubbock, Texas, and the HIPLEX <br />field operations center at Big Spring, Texas. Visible and infrared (IR) <br />imagery was received nearly continuously alternating every 30 min from <br />May 20 to July 29, 1979. These data were collected and gridding infor- <br />mation was checked in the field (Jurica et ale 1981). Digital imagery <br />for selected days was collected using the satellite ground station at <br />Colorado State University and was processed on the ADVISAR (All Digital <br />Video Imaging System for Atmospheric Research) system (Reynolds et al., <br />1978; Reynolds and Smith, 1979; Reynolds and Vonder Haar, 1979). <br />Video tape time-lapse sequences from the ADVISAR for most days were used <br />in the classification of mesoscale types along with the GOES photographs <br />as described by Matthews (1980). The video tape information was useful <br />for general classification; however, navigation was generally! 40 km <br />and resolution 10 to 30 km. GOES imagery generally had resolutions at <br />satellite subpoint of 4 km (visible) and 8 km (infrared) with some <br />higher 2 km resolution visible data. <br /> <br />GOES sectors received were generally KB-8 or KB-4 which cover the <br />central plains and the southern plains through southern Mexico, respec- <br />tively (Corbell et al., 1977, Ludwig, 1974). Occasionally, the <br />KA-4 2 km visible sector was received. <br /> <br />38 <br />
