https://spdf.gsfc.nasa.gov/pub/data/isee/isee3/2_min_merged_mag_plasma/aareadme.txt This interface provides access to a field/plasma-merged 2-min ISEE3 data set created at NSSDC as part of preparing ISEE3 data for new OMNI. Input to the data set were 1-min MAG magnetic field data, 24-s plasma data, and daily spacecraft position data, all obtained from the https://spdf.gsfc.nasa.gov/pub/data/isee/isee3/ from which needed documentation may be found. The annual files of this ASCII data set may be accessed at FTP site https://spdf.gsfc.nasa.gov/pub/data/isee/isee3/2_min_merged_mag_plasma/ as well. Time span: Mag field: 1978-09-11 - 1982-10-12 Plasma: 1978-09-11 - 1980-02-19 The contents of each of the 2-min merged records - WORD FORMAT MEANING UNITS/COMMENTS 1 I4 Year 1978,1982, etc. 2 I4 Decimal Day January 1 = Day 1 3 I3 Hour 0,1,...,23 4 I3 Minute 0,2,...,58 5 F6.1 BX SE-Coordinate System* nT 6 F6.1 BY SE-Coordinate System* nT 7 F6.1 BZ SE-Coordinate System* nT 8 F6.1 Field Magnitude Average |B| nT 9 F6.0 Proton flow speed km/s 10 F6.1 Proton flow asimuth deg. 11 F6.1 Proton flow latitude deg. 12 F6.1 Plasma Proton density [n/cc] 13 F9.0 Plasma Temperature degrees, K 14 F8.2 X, GSE Re 15 F8.2 Y, GSE Re 16 F8.2 Z, GSE Re * Note: SE- Spacecraft-centered Solar-Ecliptic coordinates. --------------------------------------------------------------- Note that an FTPHelper interface to this dataset, providing data subsetting and and graphical browsing, is available at "http://ftpbrowser.gsfc.nasa.gov/" -------------------------------------------------------------- Related data and directories: SPDF Data and Orbits Services -------------- SPDF Contact: Natalia Papitashvili , Please acknowledge NASA's Space Physics Data Facility for data usage.
