00readme.txt
This directory provides access to monthly ASCII files of 1-hour resolution
Wind/MFI magnetic field data. The data set was created at Goddard's Space Physics
Data Facility (SPDF) from multi-resolution data provided to SPDF during and after
October, 2011, in CDF format by Goddard's Wind/MFI team.
Each data record has the content and formats:
Word Field Name Format Comments
1 Year I4
2 Month I3 01-12
3 Day I3 01-31
4 Hour I3 00-23
5 Min I3 at midpoint of average; typically 30
6 Bx,GSE F10.3 nT (same as Bx,GSM)
7 By,GSE F10.3 nT
8 Bz,GSE F10.3 nT
9 By,GSM F10.3 nT
10 Bz,GSM F10.3 nT
11 Bt F10.3 nT, average of finer scale magnitudes
12 RMS,Bx,GSE F9.3 nT, rms standard deviation of Bx,GSE
13 RMS,By,GSM F9.3 nT
14 RMS,Bz,GSM F9.3 nT
15 RMS,Bt F9.3 nT
16 number_fts_pts I6 number of fine scale points in average
17 Rx,GSE F9.3 Re, GSE X component of Wind position vector
18 Ry,GSE F9.3 Re, Re = Earth radii
19 Rz,GSE F9.3 Re
20 Ry,GSM F9.3 Re
21 Rz,GSM F9.3 Re
In the above format, at least one space is allowed between fields in the In
or Fx.y statements (e.g., I3 for hour).
Fill values are of the form E10.2 and have the value -1.00E+31 for the
fields designated F10.3 above. Fill values are of the form E9.1 and
have the value -1.0E+31 for the fields designated F9.3 above.
