COMPUTER PROCESSING OF MESOSCALE RAWINSONDE DATA FROM PROJECT STORMY SPRING.

This report documents the data reduction procedures used for processing the mesoscale rawinsonde data obtained during Project Stormy Spring. Temperature and humidity data at each pressure contact about each half-minute and azimuth and elevation data at either two or ten times per minute were entered on punched cards. The 50-mb layer data for a series of soundings at one station were computed and used in another program to compute local time derivatives and single-station thermodynamic vertical velocities. Data at numerous isobaric and isentropic levels were obtained by interpolation. Data output took a variety of forms including listings of soundings, time sections, isobaric and isentropic plane sections, mechanical plots of soundings of Skew-T log P diagrams, time traces, punched cards, and magnetic tapes.
