https://spdf.gsfc.nasa.gov/pub/data/wind/mfi/ascii/1min_ascii/ 00readme.txt This directory provides access to monthly ASCII files of 1-min 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. ------------------------------------------------------------------- Related data and directories: SPDF Data and Orbits Services -------------- SPDF Contact: Natalia Papitashvili , Please acknowledge NASA's Space Physics Data Facility, and the Principal Investigator Dr. Adam Szabo of NASA/GSFC.
