Abstract
A weak tropical depression moved out of the Gulf of Mexico on Sept. 19–20, 1969. With the blocking action of a surface High and in the absence of steering currents aloft, the Low became stationary on the Florida coast for approximately 48 hr. Torrential rains occurred in a small area 60–65 mi to the east and 50 mi inland from the point where the Low made landfall. Record-breaking floods resulted. The 23-in. maximum point rainfall was about 9 in. greater than the previous maximum rainfall of record produced by a 1924 tropical storm in the same area. The location of the area of maximum rainfall with respect to the point of landfall of the Low's center closely follows the pattern previously reported for the more intense hurricanes and tropical storms.

Abstract
In June 1982 a multi-detector infrared grating spectrometer was carried by a balloon to an altitude of 39 km at Palestine, Texas, where it measured intensities of solar radiation transmitted by the stratosphere before and during sunset. The instrument detected radiation continuously in eight spectral intervals in the infrared, including two in the 9.6 μm absorption band of ozone, two near 6.6 μm in the water vapor absorption band, and one in the 11.3 μm band of nitric acid. These data permitted retrievals of concentrations of ozone, water vapor and nitric acid at 1 km intervals between the altitudes of 25 and 39 km. The ozone retrieval was compared with in-situ measurements made by ECC-sondes, which were available below 32 km. The measurements by the two systems were in good agreement. No in-situ data were available to be compared with the retrieved ozone profile above 32 km or with the water vapor and nitric acid retrievals. However, these retrievals agreed qualitatively with other measurements made in past years.
