        "Description": "The Mars Global Surveyor magnetic field instrument consists of dual, triaxial fluxgate magnetometers, capable of measuring fields between +/- 4 nT and +/- 65536 nT. Automated range switching allows the instrument to maintain maximum digital resolution over a wide range of field strengths. The text of this instrument description has been abstracted from the   instrument paper:  Acuna, M. A., J. E. P. Connerney, P. Wasilewski, R. P. Lin,     K. A. Anderson, C. W. Carlson, J.

The development of the netCDF files was supported by the NASA Postdoctoral Program Fellowship awarded to Teresa Esman in 2022.  The success of the MGS MAG project is owed to, among others, the people listed here: https://mars.nasa.gov/mgs/people/.  Addtional information on the MAG dataset can be found at: https://mgs-mager.gsfc.nasa.gov/status.html. Documentation on MGS MAG data on the PDS has been maintained by J.E.P. Connerney, Mark Sharlow, D. Kazden, J. Springborn, and B. Semenov, among others.  Teresa Esman, now a NPP Fellow at NASA Goddard Space Flight Center, compiled MGS MAG low resolution and high resolution data products, translated time to unix time, and performed the  calculation and interpolation (to high resolution) of the altitude data product.",
