Positive and negative ion composition measurements in the D- and E-regions during the 26 February 1979 solar eclipse

Measurement of Negative Ions in the Lower Ionosphere (D-Layer) in the Polar Region.

“…Several results have been reported on the observation of the D-layer in polar regions (Arnold and Krankowsky, 197 1;Amoldetal.,1971;Narcisi etal.,1971;Viggiano etal.,1982), inmid-latitude regions (Widdel et al, 1971(Widdel et al, , 1976Rose and Widdel, 1972), and in the equatorial region (Sampath et al, 1992). Other observations have been made in the solar proton event (Swider and Kaneshea, 1978), in PCA (Swider and Narcisi, 1975), in the eclipse (Narcisi et al, 1983;Conley et al, 1983;Swider and Narsici, 1983;Swider, 1988) and at mesopause (Gangly, 1984). In Japan, observations are made by using a Gerdien condenser, which confirmed the existence of negative ions (Takagi et al, 1980).…”

Airborne mass spectrometers: four decades of atmospheric and space research at the Air Force Research Laboratory

“…Therefore, near the end of the 1970s, the basic rocket instrument was redesigned in order to improve the sampling of cluster ions. 39,40 Several major changes were needed and a schematic of the redesigned instrument is shown in Fig. 5.…”

“…It is a pleasure to acknowledge the dedication of the many scientists, engineers, technicians and data analysts who, for nearly 40 years, have built, tested, flown and understood the mass spectrometry experiments. Many of these people predate our own tenures at AFRL and deserve the credit for the early work.…”

In situmass spectrometry and ion chemistry in the stratosphere and troposphere

“…The first measurements in the atmosphere on a rocket were by Narcisi and co-workers (15)(16)(17)(18)(19) (21,22). Other rocket measurements were made by Kopp and coworkers at the University of Bern (11)(12)(13)(14), Goldberg and co-workers at NASA Goddard (23)(24)(25), and Arnold and Krankowsky at the MPI-K (26)(27)(28).…”
