Interplanetary Medium Data Book - Supplement 3 - 1977-1985

Sep 15, 2026

The updating of the hourly resolution near-Earth solar wind data compilation is addressed, followed by the presentation of supporting data plots and listings. Detailed explanation is given for time shifting of ISEE 3 magnetic field and plasma data using corotation delay. Normalizations are discussed for IMP (MIT), ISEE 3, and ISEE 1 temperatures and densities to equivalent IMP (LANL) values, clarifying the arbitrariness involved in combining data sets and the nature of random differences between them.

Much of the computer progr amming for this supplement wasperformed by Howard A.Leckner.His thoroughness and perseveranceare greatly appreciated.

FAQs

What does the supplement focus on regarding near-Earth solar wind data?

It discusses updating an hourly resolution near-Earth solar wind data compilation and provides data plots and listings to support that work.

How is time shifting of ISEE 3 data handled?

Time shifting of ISEE 3 magnetic field and plasma data is explained using corotation delay.

What normalization is performed for temperatures and densities across data sets?

Temperatures and densities from IMP (MIT), ISEE 3, and ISEE 1 are normalized to equivalent IMP (LANL) values, and the arbitrariness and random differences in combining sets are clarified.
