The polar mesosphere is characterized by a very high radar backscattering coefficient. Both radar and in situ rocket spectra indicate that two qualitatively different scattering mechanisms are operating: one turbulent and one edge-like. Fourier analy

During the DYANA campaign, a Skylark VI rocket, known as SISSI-1 and containing an infra-red grating spectrometer and other onboard instruments including an atomic-oxygen sensor, was launched at dawn twilight from Esrange, Kiruna, Sweden. Molecular v

A Super Arcas rocket, MISTI B, was launched as part of the Polar Mesospheric Summer Echoes (PMSE) salvo to measure electron density irregularities using rf and dc probes. Large and small scale structures in the electron density were measured on rocke

We report about a quantitative comparison of rocket observations of electron density fluctuations and simultaneous 53.5 MHz radar measurements that were obtained during the MAC/SINE campaign in northern Norway in summer 1987. Out of three rockets lau

Two radars respectively operating at 53.5 MHz and 224 MHz have been used to simultaneously measure the polar mesospheric summer echoes (PMSEs) during the launch of a sounding rocket designed to measure the fluctuations in the electron density in the

The altitude distribution of O(³P) above White Sands, New Mexico (33°N), was investigated in situ at 1900 hours MST (0200 UT) on December 2, 1975. A rocket-borne OI 1304-A resonance-scattering system provided data over the altitude range 75-126 km

A positive ion mass spectrometer was included in a Black Brant rocket pay load fired from Poker Flat, Alaska, on March 16, 1972, in the Ice Cap 72 program. Measurements were obtained between 100 and 145 km on ascent and down to 72 km on descent durin

In the Energy Budget Campaign two rockets, one from Andoya Rocket Range, Norway, and one from Esrange, Sweden, each carrying a liquid helium cooled infrared spectrometer, were simultaneously launched as part of salvo B. The launches occurred during t
