The data were computed from the orginal ionograms using Jackson's method (Jackson, Proceedings of the IEEE., p. 960, June 1969).ISIS-1 was launched on 1969-01-30 into an elliptical orbit (500-3500km) with an inclination of 88.4 degrees and ISIS-2 was launched on 1971-04-01 into an circular orbit at 1400 km with an inclination of 88.1 degrees.Both satellites were fully instrumented ionospheric observatories including sweep- and fixed-frequequency ionosondes, a VLF receiver, energetic and soft particle detectors, an ion mass spectrometer, an electrostatic analyzer, an Langmuir probe, a beacon transmitter, a cosmic noise experiment and ISIS 2 also carried two photometers. A tape recorder with 1-h capacity was included on both satellites. Data were also collected during overflights of several telemetry stations. The telemetry stations were in areas that provided primary data coverage near the 80-deg-W meridian and in areas near Hawaii, Singapore, Australia, the UK, Norway, India, Japan, Antarctica, New Zealand, and Central Africa. <_Description>Source: Master/CDFglobalAttributes/TEXT <_Rights> SPDX Creative Commons Zero v1.0 Universal https://spdx.org/licenses/CC0-1.0.html https://spdx.org/licenses/ https://cdaweb.gsfc.nasa.gov/ISIS_ALOUETTE_DOCS/I1_NEPROF_TOPS_full_listing.txt (shows data availability) ISIS1 full listing <_Note>URL also in all.xml.
