    Synopsis of D- and E-region electron densities during the energy budget campaign (1982)
    In:  Other Sources
    Details
    Publication Date: 2011-08-18
    Description: Electron density profiles from ground-based and rocket-borne measurements conducted at three sites in northern Scandinavia under various degrees of geophysical disturbances are presented. These data are checked against an instantaneous picture of the ionospheric absorption obtained via the dense riometer network. A map of the riometer absorption and measured electron densities over Scandinavia is given.

    Case study of modeled and measured D-region plasma densities (1989)
    In:  CASI
    Details
    Publication Date: 2013-08-31
    Description: Two of the many sounding rockets launched as part of the MAC/Epsilon campaign are particularly suited to test the validity or quality of D region models. The measurements covered atomic oxygen, neutral temperatures and fluxes of charged particles. With these parameters as inputs, one is thus in the position to assess their relevance for the measured parameters, i.e., ion composition, transition heights of clusters and negative ions and total plasma density. The two IOMAS payloads are believed to be the only night flights with associated measurements of atomic oxygen extending below the ledge at about 80 km.

    Plasma phenomena observed in the MAP/WINE campaign (1989)
    In:  CASI
    Details
    Publication Date: 2013-08-31
    Description: The wealth of plasma data gathered in the MAP/WINE campaign allows insight into the generation of electron densities on a large, and the nature of the ions on a small scale. The associated measurements of winds and charged particles help to understand the morphology of the midlatitude ionization which turns out to correlate poorly with geomagnetic activity, but at least slightly with the prevailing winds. A somewhat clearer connection seems to exist between stratospheric warmings and radio wave absorption minima. On the local scale the interpretation of the rocket measurements of positive ions was helped by simultaneous observations of temperatures and atomic oxygen. The relevance of the description winter anomaly for high latitude electron density profiles are examined.

    Synopsis of the D- and E-regions during the energy budget campaign (1985)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: Electron density profiles derived from rocket-borne measurements are presented. These data were obtained at two different sites in northern Scandinavia under various degrees of geophysical disturbance. The observed electron density profiles are related to ionospheric absorption as observed with the dense riometer network in that area.

    Small-scale structure of O2(+) and proton hydrates in a Noctilucent Cloud and polar mesospheric summer echo of August 9/10 1991 above Kiruna (1993)
    In:  Other Sources
    Details
    Publication Date: 2019-08-28
    Description: A novel mass spectrometer designed to measure simultaneously positive ion composition in the mesosphere, was successfully launched during the NLC-91 project. Instruments supporting the mass spectrometer were a probed to measure both electrons and positive ions as well as a wave propagation experiment. The location of the Noctilucent Clouds (NLC) was determined by a particle impact sensor to detect secondary electrons and ions from the impact of NLC particle. The density of proton hydrates and of the related total ions is depleted in the NLC region at 83 km. An improved detection limit of 5 x 10(exp 4)/cu m for positive ions and improved height resolution revealed for the first time large gradients in the O2(+), H(+)(H2O)2 and H(+)(H2O)6 densities within a small height range of the order of 50 m. Such gradients at the altitude of NLC and Polar Mesospheric Summer Echoes (PMSE) are associated with strong variability of mesospheric water vapor, temperature and neutral air density.
