The term     composition includes both the type of neutral gases present     and their quantitative amount. The measurements begin at the     orbit's periapsis altitude and extend to a limiting altitude     at which the ambient signal becomes comparable to the gas     background and/or detector measurement threshold.  The neutral     composition includes helium, atomic nitrogen, atomic oxygen,     molecular nitrogen, carbon monoxide and carbon dioxide. The     data reduction has been described in Niemann et al. (1980a) and     Kasprzak et al. (1980).", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.pvo-v-onms-4-neutraldensity-12sec-v1.0;urn:nasa:pds:context_pds3:data_set:data_set.pvo-v-onms-4-neutraldensity-12sec-v1.0::99.0", "keyword": ["__"], "license": "https://www.usa.gov/government-works", "modified": "2026-04-06", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "planetary plasma interactions"}, "theme": ["Planetary Science"], "title": "PVO VENUS ONMS BROWSE NEUTRAL                                      DENSITY 12 SECOND V1.0"}
