There are three different types of files archived in RASM-ESRL/ModelOutput.

1) Figures from forecasts:
All plots created for the daily forecasts are archived in tar balls named
CASENAME_plots.YEAR-MONTH-DAY.tar.gz. To access the figures untar the file with the
command tar -xvfz.

2) Fields from CICE model:
A subset of fields from the CICE model history tapes are archived in
the netcdf files ending with ".nc". The fields are 6-hourly
averages. Fields can be viewed with ncdump or ncview commands.
Fields in each file are time,TLON,TLAT,ULON,ULAT,ANGLE,ANGLET
hi_h = grid cell mean ice thickness (meters)
hs_h = grid cell mean snow thickness (meters)
Tsfc_h = snow/ice/surface temperature (Celcius)
aice_h = ice area (aggregate)
uvel_h = ice velocity (x) (m/s)
vvel_h = ice velocity (y) (m/s)
uatm_h = atmosphere velocity (x) (m/s)
vatm_h = atmosphere velocity (y) (m/s)
Tair_h = air temperature (Celcius)

3) Fields formatted for the National Ice Center:
Fields in tar balls named RASM-ESRL_4NIC_YEAR_MONTH_DAY.tar.gz are
netcdf time slices formatted for the National Ice Center. Are fields
in the netcdf files are in short format. The fields are 6-hourly
averages. Archived fields are TLON,TLAT,ULON,ULAT:
time = valid time (hour since 2000-01-01 00_00_00) (double format)
tau = hours since analysis (double format)
hi = grid cell mean ice thickness (meters)
hs = grid cell mean snow thickness (meters)
Tsfc = snow/ice/surface temperature (Celcius)
aice = ice area (aggregate)
uvel = eastward ice velocity (m/s)
vvel = northward ice velocity (m/s)
snow = lwe snowfall rate (cm/day)
rain = rainfall rate (cm/day)
sst = sea water temperature (Celcius)
sss = sea water salimity (psu)
uocn = eastward sea water veloctiy (m/s)
vocn = northward sea water velocity (m/s)
Tair = air temperature (Kelvin)
meltt = top ice melt (cm/day)
meltb  = basil ice melt (cm/day)
meltl = lateral ice melt (cm/day)
strength = compressive strength of sea ice (N/m)
divu = divergence of sea ice velocity (%/day)
