    Description: Satellite instruments such as the backscattered ultraviolet (BUV) apparatus, have been in operation for a number of years. One current difficulty is the validation of the ozone inferences obtained from the BUV measurements using independent instruments. For higher altitudes rocket instruments are necessary. Two instruments currently under development include a chemiluminescent detector described by Hilsenrath et al. (1969) and a filter photometer rocket ozonesonde (Rocoz) developed by Krueger and McBridge (1968). The present investigation is concerned with an analysis of the Rocoz system, the information content of the measurements, and the utility of the system for intercomparison with the BUV system. It is found that the sampling characteristics of the Rocoz and BUV systems exhibit some fundamental differences. However, their results can be related through knowledge of the relation between pressure and altitude. This is best obtained through the solution of the hypsometric equation using rocket temperature measurements.

    Description: A rocket carrying an optical ozonesonde was launched at 1822 GMT on Sept. 29, 1977 in support of the STRATCOM 8 balloon. The integral ozone amount above the balloon ceiling altitude of 40 km was measured as .0117 atm-cm with an uncertainty less than + or - 7%. The ozone density at 40 km was 6.77 x 10 to the 17th power mol/cu m. Ozone densities in molecules/cu m at higher altitudes were 2.28 x 10 to the 17th power at 45 km, 6.72 x 10 to the 16th power at 50 km, 2.20 x 10 to the 16th power at 55 km, and 7.26 x 10 to the 15th power at 60 km. In addition, the ozone distribution was measured at lower altitudes from the tropopause at 17 km to 40 km.

    Description: Complete data from a total of 43 meteorological rocket soundings of the stratosphere and mesosphere conducted from Barrow, Alaska; Churchill, Canada; Wallops Island Va.; and Kourou, French Guiana are presented. These data consist of temperature, pressure, density, and wind profiles from 35 acoustic grenade soundings that cover the 30 to 90 km altitude range, and temperature, pressure, and density profiles from 8 pitot probe soundings that cover the 25 to 120 km altitude range. Errors for each of the 35 acoustic grenade soundings are also included.

    Description: Complete data from a total of 26 meteorological rocket soundings of the stratosphere and mesosphere conducted from Barrow, Alaska; Churchill, Canada; and Wallops Island, Va., are presented. These data consist of temperature, pressure, density, and wind profiles from 16 acoustic grenade soundings that cover the 30- to 90-km altitude range, and temperature, pressure, and density profiles from 10 pitot probe soundings that cover the 25- to 120-km altitude range. Errors for each of the 16 grenade soundings are also included. No analysis of the meteorological significance of the data is attempted.

    Description: During the period March 1977 through May 1977, three regular monthly ozone profiles were measured at Wallops Flight Center and three regular monthly ozone profiles were measured at the Churchill Research Range. One additional flight was conducted at Wallops Flight Center in support of Nimbus 4 SBUV. Data results and flight profiles for the period covered are presented.

    Description: Atmospheric measurements between 30 and 90 km using two rocket-borne techniques - the inflatable falling sphere and the acoustic grenade - are compared in order to determine temperature measurement compatibility. The falling sphere, deployed at 115 km, is tracked by precision radar to determine winds as well as accurate drag parameters needed to deduce density from which temperatures are derived. The acoustic grenade technique uses sound arrivals at the ground from grenades ejected at 2-km intervals to determine temperature and wind between 40 and 90 km. The available data were obtained during an in-situ techniques-comparison with the remote sounders aboard Nimbus 6 during the summer and winter of 1975.
