General Details of MGITM datasets for MAVEN/NGIMS Winds Campaigns

*****************************************************************************************

NGIMS Winds Campaigns (Roeten et al., 2019):
-------------------------------------------------------------------------
Campaign      Dates               Orbits          Season (Ls)
-------------------------------------------------------------------------
1.	September 22-23,2016    3861-3865         227-229    
2.	January 11-13, 2017     4437-4446         297-299
3.	May 30 - June 1, 2017   5170-5179          12-13
4.	December 7-8, 2017      6198-6202          97-98
5.	February 7-9, 2018      6532-6541         126-127

*****************************************************************************************

MGITM Results are presented on a regular GEO grid (Longitude-Latitude-Altitude):
-------------------------------------------------------------------------
LON (72 elements) =   2.5 to 357.5 by 5.0 degree interval (fastest index)
LAT (36 elements) = -87.5 to +87.5 by 5.0 degree interval
ALT (62 elements) = 98.75 to 251.25 km by 2.5 km interval  (slowest index)

                    where

LON (2.5 to 180 to 357.5E) corresponds to SLT = 12 to 24 to 12
(We have selected the proper UT for each dataset for this match)

Fields (17):
-- Temperatures             : Tn, Ti, Te
   (neutral, ion, electron)
-- Major neutral densites   : [CO2], [O], [N2], [CO], [O2]
-- Major plasma densities   : [O2+], [O+], [CO2+], [Ne]
   (dayside only, best in PCE region below 200 km)
-- 3-component neutral winds: Un, Vn, Wn
-- Pressure (total)         : P
-- Solar Zenith Angle       : SZA
Units  = All Temperatures (K),  All densities (#/m3), 3-component winds (m/s),
         Pressure (pascals), SZA (degrees)

File Nomenclature:
------------------------------
mgitm.YYMMDD.utXX.MonthYear.dat

YY = last 2-digits of year
MM = 2-digit month
DD = 2-digit day of month
XX = Universal Time (on Earth): 2-digit integral hours
MonthYear = NGIMS wind campaign case

e.g. mgitm.160922.ut20.SEPT2016.dat
YY = 16
MM = 09
DD = 22
XX = 20
MonthYear = SEPT2016
