Package ``sbo'' calculates the core products of the IERS Special Bureau |
\begin{verbatim} |
| 9 |
for the Oceans including oceanic mass, center-of-mass, angular |
Subdirectory pkg/sbo contains a small diagnostic package that computes IERS |
| 10 |
momentum, and bottom pressure. The main routine is sbo\_calc. |
Special Bureau for the Oceans (SBO) core products, including oceanic mass, |
| 11 |
|
center-of-mass, angular, and bottom pressure. The package is enabled by |
| 12 |
|
adding sbo to packages.conf and "useSBO=.TRUE." in data.pkg during model |
| 13 |
|
execution. There are two separate output products, SBO_DIAG.* and |
| 14 |
|
OBPtave*, which are described below. |
| 15 |
|
|
| 16 |
|
=========== |
| 17 |
|
|
| 18 |
|
SBO_DIAG.data is a single file that contains the following fields at every |
| 19 |
|
model time step: |
| 20 |
|
|
| 21 |
|
myCurrentTime - model integration time (s) |
| 22 |
|
xoamc - x-comp oam due to currents (kg-m**2/s) |
| 23 |
|
yoamc - y-comp oam due to currents (kg-m**2/s) |
| 24 |
|
zoamc - z-comp oam due to currents (kg-m**2/s) |
| 25 |
|
xoamp - x-comp oam due to pressure (kg-m**2/s) |
| 26 |
|
yoamp - y-comp oam due to pressure (kg-m**2/s) |
| 27 |
|
zoamp - z-comp oam due to pressure (kg-m**2/s) |
| 28 |
|
mass - mass of oceans (kg) |
| 29 |
|
xcom - x-comp of center-of-mass of oceans (m) |
| 30 |
|
ycom - y-comp of center-of-mass of oceans (m) |
| 31 |
|
zcom - z-comp of center-of-mass of oceans (m) |
| 32 |
|
|
| 33 |
|
The file is direct access, real*8, binary. Its dimensions are 11 X nt, where |
| 34 |
|
nt is number of records. For example, in matlab you can use |
| 35 |
|
|
| 36 |
|
sbo=readbin('SBO_DIAG.data',[11 nt],1,'real*8',0,'native'); |
| 37 |
|
|
| 38 |
|
to obtain the 11 X nt matlab array sbo. A copy of readbin.m resides in |
| 39 |
|
subdirectory verification/lab_sea/matlab. |
| 40 |
|
|
| 41 |
|
=========== |
| 42 |
|
|
| 43 |
|
OBPtave* files contain ocean-bottom pressure in Pascals (N/m^2). Ocean bottom |
| 44 |
|
pressure is cumulated and averaged for sbo_taveFreq seconds. Parameter |
| 45 |
|
sbo_taveFreq is specified in data.sbo during model execution. For example: |
| 46 |
|
|
| 47 |
|
# SBO parameters |
| 48 |
|
&SBO_PARM01 |
| 49 |
|
sbo_taveFreq = 86400. |
| 50 |
|
& |
| 51 |
|
|
| 52 |
|
will average and dump bottom pressure once per day. The bottom pressure files |
| 53 |
|
are 2-dimensional fields with dimension nx X ny equal to those of the model |
| 54 |
|
domain. The files have standard MITgcmUV mdsio output format. The files are |
| 55 |
|
direct access, real*4, binary. They can be global or tiled (depending on |
| 56 |
|
whether "globalFiles=.TRUE." is set in parameter file data). For example, in |
| 57 |
|
matlab you can use |
| 58 |
|
|
| 59 |
|
obp=readbin('OBPtave0000000020.data',[nx ny],1); |
| 60 |
|
|
| 61 |
|
to read a global bottom pressure file output at model time step 20. Land is |
| 62 |
|
flagged with -999.99 values. |
