Having obtained the detailed daily preceiptation records <br />on punched cards, these data could then be analyzed by machine prooesses. <br /> <br />Using the guidanoe of findings of Step No.1, it should be <br />possible to give a much more complete ana1,ysis of the precipitation <br />frequenoy patterns and to study them as related to actual streamflow, <br />either by small seotions of the Upper Colorado 'Basin or the entire <br />main stem flow below several oambined stations. <br />. . . . <br /> <br />It is a well known fact th/l.t IllD8.ll quantities of precipita- <br />tion contribute practically nothing to stream flow. With daily <br />preoipitation data on punched ca1'ds it would be easy to analyze <br />these, eliminating the lower precipitation quantities to thus test <br />for the highest correlation between preoipitation records andstresm- <br />flow data. <br /> <br />It is expected th/l.t at this stage same adClitional effort, <br />shouJ.d be expended to include snow pack: data which would expan4 the <br />compos~te record of precipitation totaJ.s contributing subsequently <br />to stream flow. Since snow pack: measurements are made only on a <br />month-t_onth basis iiuring the winter months, the,y may not lend <br />themselves well to machine tabulations, but certainly could be used <br />for cross reference to the preoipitation quanti-tiestreated in the <br />punched card analyses. . <br /> <br />FACILITIES <br /> <br />The placing of precipitation (and temperature) reoords on <br />punch cards wouJ.d be performed at the Colorado State University <br />Researoh Foundation under the direction of Dr. A. R. Chamberlin. <br />Punch card data since 1948 are available fram the United States <br />Weather Bureau on an exchange basis. <br /> <br />PERSONNEL <br /> <br />Gll1Ieral supervision of this phase of meteorological research <br />wouJ.d be the responsibility of Dr. Morris E. Garnsey and the Bureau <br />of Economic Researoh, University of Colorado. Mr. Loren Crow, <br />consulting meteorologist, and Mr. Rioh/l.rd Schluesener, meteorologist <br />at Colorado state University, wOuld carry out this study in collabor- <br />ation with Dr. A. R. Chamberlin. The staff meteorologist, Mr. Norman <br />J. Macdonald of High Altitude. Observatory wouJ.d also act in an <br />advisory capacity. . <br />
