Comparison ofTeandTifrom Ogo 6 and from various incoherent scatter radars

摘要: Langmuir probe and retarding potential analyzer (RPA) data on the electron ion temperatures Te Ti obtained from Ogo 6 are compared with values incoherent scatter network. The satellite to radar temperature ratio TeS/TeR is 1.15 average for these comparisons. This discrepancy larger than uncertainties usually placed values. It is, however, a smaller that found in many previous comparisons of this type. Our do not appear give any insight into cause discrepancy. TiS/TiR approximately 1.0, independent particular examined. internal accuracy RPA set was ±5% or better. Thus comparison serves as an intercalibration Since no significant systematic errors (i.e., statistical errors) exist between data, it appears very unlikely either set. should be noted, were limited mainly nighttime hours thus relatively low heavily weighted altitudes 400 600 km, where suspected sources error minimum.
