In-situ electron and ion measurements and observed gravity wave effects in the polar mesosphere during the MaCWAVE program
Langmuir probe electron and ion measurements from four instrumented rockets flown during the MaCWAVE ( M ountain a nd C onvective W aves A scending VE rtically) program are reported. Two of the rockets were launched from Andøya Rocket Range, Norway, in the summer of 2002. Electron scavenging by ice...

Two of the rockets were launched from Andøya Rocket Range, Norway, in the summer of 2002. Electron scavenging by ice particulates produced reductions of the electron density in both sharp narrow (≈1–2 km) layers and as a broad (≈13 km) depletion. Small-scale irregularities were observed in the altitude regions of both types of electron depletion.
