NOGAPS 0.5c Print

The files in nogaps0.5c come from the GODAE server and they start in 2003. They do not contain any forecasts. These are continually updated (about once per week). When we process forcing products, we'll put all variables into their own files, and additionally we'll merge certain variables because that is what the interpolation code expects. For a specific year, we have these fields like:

nogaps0.5c-std_2011_03hr_TaqaQrQp.D
nogaps0.5c-std_2011_03hr_Taqa_day-QrQp.D
nogaps0.5c-std_2011_03hr_dwpt2m.D
nogaps0.5c-std_2011_03hr_lndsea.D
nogaps0.5c-std_2011_03hr_longwv.D
nogaps0.5c-std_2011_03hr_mslprs.D
nogaps0.5c-std_2011_03hr_soiltm.D
nogaps0.5c-std_2011_03hr_solrad.D
nogaps0.5c-std_2011_03hr_spchum.D
nogaps0.5c-std_2011_03hr_strblk.D
nogaps0.5c-std_2011_03hr_strpbl.D
nogaps0.5c-std_2011_03hr_temp2m.D
nogaps0.5c-std_2011_03hr_uv-10m.D
nogaps0.5c-std_2011_03hr_wndspd.D
TaqaQrQp:
a merged file of temp2m (air temp at 2m), spchum (specific humidity), radiative fluxes that is composed of solrad (net surface shortwave) minus longwv (net surface longwave) and penetrating radiation (solrad). This field is the input thermal forcing file for a HYCOM simulation. The fields in this file have a daily filter applied to them.
Taqa_day-QrQp:
These are like the TaqaQrQp daily filtered files, but Ta and qa are NOT daily filtered whereas QrQp ARE daily filtered.
TaqaQlQg:
These files are used by CICE when running coupled HYCOM/CICE. Taqa are the same as in the TaqaQrQp files, but Ql is net surface longwave radiation and Qg is downward surface shortwave radiation (glbrad).
dwpt2m:
dewpoint temperature at 2 m (Kelvins)
lndsea:
the atmospheric model's land/sea mask
longwv:
net surface longwave (W/m^2)
mslprs:
mean sea level pressure (hPa/100 - 1000)
soiltm:
surface (land and ocean) temperature (Kelvins)
solrad:
net surface shortwave (W/m^2)
spchum:
specific humidity (kg/kg)
strblk:
bulk-derived wind stress (N/m^2)
strpbl:
planetary boundary layer wind stress (N/m^2)
temp2m:
air temperature at 2 m (Kelvins)
uv-10m:
zonal and meridional wind components (m/s)
wndspd:
wind speed (m/s)

The lndsea files is actually dynamic for nogaps0.5c with: 0 = OCEAN, 1 = LAND, 2 = ICE, 3 = SNOW.

Often the wind stress curl field associated with the strpbl file is very noisy so traditionally we have always used the strblk stresses to force HYCOM. Nonetheless, we keep both sets of stresses.

For the set of files listed above, there are nogaps0.5c-sea versions. For the QuikSCAT corrected winds and stresses, these are the 'sec' files. Note there are secC and secD versions. For uv-10m and wndspd, the secC are the appropriate files to use but for strblk the secD file is appropriate. For simplicity, we simply call them sec (without the C or D).

e.g.,

nogaps0.5c-sec_2008_03hr_strblk.D 
  -> nogaps0.5c-secD_2008_03hr_strblk.D
nogaps0.5c-sec_2008_03hr_uv-10m.D 
  -> nogaps0.5c-secC_2008_03hr_uv-10m.D
nogaps0.5c-sec_2008_03hr_wndspd.D 
  -> nogaps0.5c-secC_2008_03hr_wndspd.D
