===============================================================================
Overview:
(a) Resolutions and inputs:
Temporal Resolution: 10 min 
Spatial resolution: 2.5 (lon) x 1.25 (lat) x 1/3 scale height (alt)
High-latitude drivers: ASHLEY-A and ASHLEY-E (by realistic IMF and solar wind)
F107: 90
Electrodynamo: on
pre-run: 3 day

(b) Names:
run0: 08/20 15-24 UT (quiet-time run)
run1: 08/21 15-24 UT (no-eclipse run)
run2: 08/21 15-24 UT (geo mask run) 
run3: 08/21 15-24 UT (euv mask run) 

===============================================================================

 1. ut: hours after 08/20 (hour)
 2. glon: geographic longitude eastward (deg)
 3. glat: geographic latitude (deg)
 4. TEC: TEC (TECU)
 5. ON2: O/N2 ratio (N/A)
 6. SolarMask: Occultation factor (N/A)

===============================================================================
(B) Files in '3dall/': 3D variables


Variables: 
-------------------------------------------------------------------------------
 #  name:   definition	(unit)
-------------------------------------------------------------------------------
 1. ut: hours after 08/20 (hour)
 2. glon: geographic longitude eastward (deg)
 3. glat: geographic latitude (deg)
 4. alt: altitude (km)
 5. Eden: electron density (m-3)
 6. Ui: zonal ion drift (m/s)
 7. Vi: meridional ion drift (m/s)

Note: 
 a. electron density profile in GITM is not raliable after midnight
 b. Wi may show large oscillations above 400 km
