NASA GMAO has provided 1-hourly mass flux fields for GEOS-FP meteorology
at c720 resolution to drive GCHP. The mass flux fields have been converted
to derived winds fields and further regridded from c720 to 0.125x0.15625
lat-lon resolution. The new files include the following collections and met
fields:

- GEOS.fp.asm.I1dyn : PS, SPHU
- GEOS.fp.asm.A1dyn : U, V

Several IF statements have been expanded to include State_Grid%GridRes =
0.125x0.15625 resolution so that grid parameters and scale factors are
properly determined.

Also updated createRunDir.sh for GCClassic to correctly set transport and
chemistry timesteps for 0.125x0.15625 resolution. For now the same default
timesteps as 0.25x0.3125 and 0.5x0.625 will be used (transport=5 min,
chemistry=10 min). This recommendation may later changed based on proper
evaluation of the 0.125x0.15625 simulations.

…s for non-dynamic fields

The 0.125x0.15625 files are only available for dynamic collections A1dyn
and I1dyn. The remaining met fields when running at this resolution should
be read at 0.25x0.3125. This file is currently hardcoded to use the North
America (NA) files at 0.25x0.3125 resolution for testing, but this should
be made more flexible in the future.

The 0.125x0.15625 files have also been updated here so that daily files are
used instead of hourly files. The use of daily 24-hour met field files has
already been implemented in GEOS-Chem, but it does not currently know how
to handle hourly files.

Xiaolin Wang identified the following bugs in the 12km simulations:

1. In GeosCore/pjc_pfix_window_mod.F90 for 12km code, we need to change the
   parameter dp in correspond with 12km resolution.
2. In the input_mod.F90, we need to improve floating point precision,
   otherwise the longitude resolution is 0.1563 rather than 0.15625.

The PS and SPHU fields at 0.125x0.15625 resolution are in the I1dyn
collection, while the U and V fields are read from the A1dyn collection.
All of these fields should be read hourly, not 3-hourly as is the case
for 0.25x0.3125 resolution and coarser. New subroutines FlexGrid_Read_A1dyn,
FlexGrid_Read_I1dyn_1, FlexGrid_Read_I1dyn_2, and Copy_I1dyn_Fields have
been added to flexgrid_mod.F90 following work by Xiaolin Wang. The code
in hco_interface_gc_mod.F90 and main.F90 that calls these routines has
also been updated. New I1dyn routines have also been added to time_mod.F90.
