Visible and infrared image data from the scanning radiometer on the NOAA-2 and NOAA-3 satellites are received by a VHF "APT" Station at Colorado State University. In addition to producing the regular hard-copy photographs, the taped signal is specially processed by electronic means, converted from analog to digital form and further processed in the computer. Details of the processing steps and equipment will be described and the meteorological application...

During the evening hours of 31 July 1976 heavy precipitation fell along the Colorado Front Range resulting in flash flooding in the Big Thompson Canyon causing the death of 139 people with 35.5 million dollar damage. This report utilizes GOES-1 infrared (IR) imagery to estimate the heavy convective precipitation during the Big Thompson Flood.

Digital imagery from the SMS 2 geostationary satellite was recorded for analysis in support of the Sierra Cooperative Pilot Project. Imagery of five storms during the 1976 77 and 1977 78 seasons of the project were analyzed. Results show the highest precipitation and lowest cloud top temperatures below 35° C occur about one or two hours ahead of the surface cold front within the frontal band. Following the frontal passage an unstable convective orographic...

For several days at the end of January and the beginning of February 1972, the components of short-wave radiation were measured over a snowfield in a valley of the Rocky Mountains at a height of 2700 m above sea level.
