1-Hour averaged magnetic field data for solar wind only

NSSDCA ID: SPHE-00874

Availability: At NSSDC, Ready for Electronic Access

Description

It was created at NSSDC by combining the hourly, all-orbit-phases data set (SPHE-00873) with IMP 8 bow shock crossing information to produce this hourly, solar-wind-only data set. This data set has annual files of hourly IMP 8 magnetic field averages, in ASCII format.

The spacecraft position values (words 5-9), the field intensity (word 10) and the GSE and GSM cartesian components (words 14-18) were computed from corresponding 15-sec values. Data for 00:00- 01:00 were used for the first hourly average of the day. Words 11-13 were computed from the hourly averaged GSE cartesian components. The number of points is the number of 15-s values (themselves averages) contributing to the hourly average. The sigma's (standard deviations) carry no memory of the sigma's in the 15-s averages.

The hourly averages of this data set contain only the solar wind phase of each ~12-day IMP orbit. Every hour is represented; those for which there are no IMP solar wind data have fill values in their data words.
