Studies of wintertime storms over the Tushar Mountains of Utah: final report to Utah Department of Natural Resources
(Colorado State University. Libraries, 1986-03-06) Rogers, David C., author; Rauber, Robert M., author; Grant, Lewis O., author; Department of Atmospheric Science, Colorado State University, publisher
Supercooled liquid water flux over the Tushar Mountains was estimated from three hour averages of the radiometer and rawinsonde observations. The amount of liquid water represented by this flux over the two-month project was 17,000 acre feet, or about 45 percent of the total annual runoff in the Beaver River watershed.

Satellite studies during the 1976-77, 1977-78 Sierra Cooperative Pilot Project: final report to the Office of Atmospheric Resources Management, Bureau of Reclamation
(Colorado State University. Libraries, 1979-02) Morris, K. Robert, author; Reynolds, David W., author; Vonder Haar, Thomas H., author; Department of Atmospheric Science, Colorado State University, publisher
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 have been analyzed in detail using the CSU ADVISAR. Temporal variations in cloud top temperature were charted and synoptic and mesoscale cloud features have been studied. Results show the highest precipitation and lowest cloud top temperatures below -35°C, occur about one or two hours ahead of the surfacecold front within the frontal band. Following the frontal passage an unstable convective orographic cloud remains over the Sierra for up to 8 hours with cloud top temperatures around -15°C well within the seeding window range. Mesoscale features including banded and cellular convection and cloud streets have been observed by the satellite with their effects often showing up in the precipitation gage records. Large convective lines and cells were tracked onshore and were found to move with the winds somewhat below the 50 kPa level. Cells intensify in the Central Valley of California usually dissipating as they climb the Sierra Trajectories of large cells curve to the left upon encountering the foothills becoming nearly parallel to the mountains under certain conditions. Precipitation is greatest on the west slopes of the Sierra due to the orographic effect. Lee-side precipitation appears to be dependent on the presence of high cold cloud tops which lead to precipitation particles being carried over the crest.

Tropical cyclone and related meteorological data sets available at CSU and their utilization
(Colorado State University. Libraries, 1982-02) Gray, W. M., author; Buzzell, E., author; Burton, G., author; Department of Atmospheric Science, Colorado State University, publisher
This report has been prepared to familiarize the international meteorological community with the comprehensive collection of tropical cyclone and other meteorological data which are available on our research project. We provide a rationale for the research philosophy behind the assembling of these data sets over the last decade, describe the data and indicate how other researchers may use them for their own the research purposes. In particular, we summarize the rawindsonde compositing philosophy and the other research techniques employed on our project. We describe our data processing procedures, the various formulations we have used for different research purposes, the coordinate systems employed and the data availability by region. Our research accomplishments, types of compositing runs, and a list of publications are also presented. These data sets and their software support represent a considerable manpower and financial investment. An investment that is now able (we believe) to provide a high return in the form of new knowledge on tropical cyclones and other weather systems. We are currently exploring a number of exciting avenues. The possibilities are quite broad and we encourage other research workers to help exploit this resource.

A pilot project of weather modification for the San Juan Mountains of the Colorado River Basin: final report
(Colorado State University. Libraries, 1974-02) Grant, Lewis O., author; Chappell, Charles F., author; Crow, Loren W., author; Fritsch, J. Michael, author; Mielke, Paul W., Jr., author; Department of Atmospheric Science, Colorado State University, publisher
This is the final report on the preparation of a design program to apply results from experimental programs for augmenting orographic precipitation to a Pilot Project that would have the goal of providing "...sound scientific and engineering evaluation of precipitation creases over a large area by operational-type application of cloud seeding techniques...", (Kahan, 1969). The report describes: (1) the purpose of the project; (2) the scientific and technological basis; (3) the design constraints; and, (4) the details of the design. The design itself includes descriptions of: (1) the experimental hypothesis; (2) the site selection; (3) the experimental procedures (randomization. etc.); (4) the data collection requirements; (5) the operations procedures; and, (6) the evaluation techniques to be employed.

Larimer County, Colorado, air pollution and outlook
(Colorado State University. Libraries, 1970-12) Riehl, Herbert, author; Herkhof, Dirk, author; Department of Atmospheric Science, Colorado State University, publisher
Planning for economic and population growth in presently rural areas would be considerably aided from the standpoint of air quality, if an assessment of future air pollution in terms of expected population growth, as a parameter, could be made. This paper attempts to make such an estimate for the foothills area just east of the Colorado Rockies near the northern border of the state. Three problems are taken up in succession, limiting attention to particulate pollution. At first, "pollution potential", defined as the probability of incidence of air pollution episodes of some minimum duration, is calculated from winds obtained during a field experiment. On the average, 10 episodes per winter taking up one quarter of a winter's time may be expected; this is a substantial fraction of total time. Next, the mechanisms of present air pollution accumulation and depletion were studied preliminary to developing daytime and nighttime models for future pollution. It is shown that a nighttime model without turbulence can reconstruct the present pollution map quite faithfully, whereas turbulent upward flux must be added in daytime, not unexpectedly. In the models, it is possible to express future pollution density in terms of wine speed and pollution source strength. Assuming a rate of 50 per cent population increase per decade, estimates of average pollution and so of pollution distribution are prepared until the year 2000.

(Colorado State University. Libraries, 1973-02-12) Grant, Lewis O., author; Brier, Glen W., author; Mielke, Paul W., Jr., author
A comprehensive analysis of the cloud seeding activities in the San Luis Valley of southern Colorado is in progress. Several more months will be required for its completion. Certain tentative conclusions are now possible. These are presented in summary form and in ·some detail in the following sections. It is planned that a technical report will be prepared and submitted to a scientific journal for publication at the completion of the study.

The Department of Atmospheric Science at CSU: a 20 year perspective
(Colorado State University. Libraries, 1982) Colorado State University. Department of Atmospheric Science, author
The CSU Department of Atmospheric Science was founded in 1962. It now has a faculty of 13 (full time), a student body of over 70 graduate students and an additional research associate and supporting staff of about 60. As part of the 20th year reunion celebration of our Department on July 1982 we have taken this occasion to issue this brief report on how our Department has grown and developed through these 20 years. Rather than having one or two people sit-down and write this report by themselves, we have decided to have a number of our current faculty members and Herbert Riehl tell the story of our Department's development in their own unedited words. A wide range of points of view are brought forth, although admittedly from the faculty point-of-view. We recognize that a similar report from our former and present graduate students, staff, and research associates might give a somewhat different perspective. But it is the faculty that have been here the longest and seen our Department evolve the most. The older faculty have primarily concentrated on our Department's development during the 1960's while the younger faculty the developments during the 1970's. This report also lists background statistical information on who has been a member of our faculty, our graduates with their degree thesis titles, and also other information on our Department's current research associates, and support staff.
