IMP_LANL Hourly Plasma data This hourly resolution data set was created at NSSDC in the year 2000 by averaging 2-min resolution solar wind data provided over the years by LANL. Magnetosheath data were excluded from the 2-min data by LANL. This data set supersedes hourly solar wind data provided by LANL over the years; these latter data were in various formats and contained many fewer parameters than the new data set. The contents/format of the merged records are: Word Format Description 1 I4 Year 2 I4 Day 3 I3 Hour 4 I4 # of points 5 F5.1 Rad. distance (Re) 6 F6.1 Latitude (Deg.) 7 f6.1 Longitude (Deg.) 8 F6.1 Density, N/cm^3 9 F6.0 Speed, km/s 10 F7.1 Flow azimuth 11 F9.0 Max Temperature, K 12 F9.0 Min Temperature, K 13 F9.0 Temperature, K 14 F7.1 Pressure tensor, deg 15 F5.2 Alpha/Prot ratio 16 F6.0 Rel. flow speed,km/sec 17 F7.1 Rel. angle,deg 18 F5.1 Alpha temp./prot. temp. ratio 19 F5.1 sigma-Rad., Re 20 F6.1 sigma-Lat. deg. 21 F6.1 sigma-Lon. deg. 22 F6.1 sigma-N, N/cm^3 23 F6.0 sigma-V, km/s 24 F7.1 sigma-Az.
