<br />Section 6. - Photographs <br /> <br />Three types of photographic data were routinely collected during the 1985-86 <br />CRADP winter activities. These were (1) surface time-lapse 16 mm photography <br />of the Grand Mesa from the roof of the Montrose office, (2) 35 mm B&W photos <br />of snow particles from the snowlab at Island Lake, and (3) 35 mm color photos <br />from the aircraft. Some 35 mm color photos were taken from Montrose on March <br />18 (11 photos) and 19 (4 photos). Some 35 mm B&W photos were taken near Delta <br />on March 18. The aircraft photos are totaled in the aircraft section of this <br />inventory. <br /> <br />The Montrose 16 mm camera was again at 38 291201lN, 107 5111911W, 1792 m (5880 <br />ft) msl. The camera was operated daily from about 1340 to 0040 GMT (0640 to <br />1740 MST) at one frame every 2 minutes. From November 27 to February 3 the <br />hours were about 0715 to 1715 MST because of shorter daylight hours. During <br />special experiments the camera was occasionally panned to record snow from <br />clouds far downwind of seeding locations at about one frame per second. <br /> <br />The periods of missing data within the October 23, 1985 to April 2, 1986 <br />operational period were: <br /> <br />0917-1505 851127; 0830-1551 851223; 0917-1626 860115; 1246 860126-0803 860127; <br />0653-1654 860202; 1419-1552 860218; 1611 860301-1203 860302; all MST. <br /> <br />The snowlab photo totals were: <br /> <br />860213-20. 860310-20. 860311-1. 860314-8. 860318-87. 860319-38. <br /> <br />6-1 <br /> <br />
