During the summer of 1980, the Burro series of liquefied natural gas (LNG) spill experiments were performed at the Naval Weapons Center, China Lake, California. These experiments involved 8 spills of LNG and one of liquid nitrogen, each of approximately 40 m/sup 3/, onto water. A large array of instruments was used to make measurements of gas concentration, temperature humidity, heat flux from the ground, and turbulence within the dispersing gas cloud. A separate instrument array made measurements of the wind field both upwind of the spill and over the area in which the gas was dispersing. Volume II contains appendices for: wind field data and flowlines; horizontal gas concentration contours; and vertical gas concentration contours.
