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 (46 elements) = 98.75 to 226.25 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 (18):
-- Temperatures : Tn, Ti, Te
(neutral, ion, electron)
-- Major neutral densites : [CO2], [O], [N2], [CO], [Ar], [He]
-- 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:
------------------------------
PEDE4B.ZZGW.E20.YYMMDD.utXX.userdetic.dat (PEDE4B contains an M-GITM simulation with
no gravity wave forcing)
or
PEDE4D.ZZGW.E20.YYMMDD.utXX.userdetic.dat (PEDE4D contains an M-GITM simulation with
gravity wave forcing included)
ZZ = Flag for yes/no for M-GITM GW formulation activation
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 = PEDE Interval
e.g. PEDE4D.YSGW.E20.180830.ut19.userdetic.dat
ZZ = YS (GW formulation turned on)
YY = 18
MM = 08
DD = 30
XX = 19
