The following analyses are available in the post-processing part of OASIS3, controlled by oasis3/src/postpro.f.
This transformation is obsolete in the current OASIS version.
REVERSE (routine oasis3/src/reverse.f) reorders a field.
This analysis requires the same input line as INVERT, with $CORLON and $CORLAT being now the resulting orientation. REVERSE does not work for U and D grids (see appendix A). Note that INVERT does not transform the associated grid or mask.
CHECKOUT (routine oasis3/src/chkfld.f) calculates the mean and extremum values of an output field and prints them to the coupler output cplout (this operation does not transform the field).
The generic input line is as for CHECKIN (see above).
This transformation is obsolete in the current OASIS version as coupling fields can be directly interpolated to a target Reduced grid, if needed; this transformation should not be used anymore.
GLORED performs a linear interpolation of field from a full Gaussian grid to a Reduced grid. When present, GLORED must be the last analysis performed.
Before doing the interpolation, non-masked values are automatically extrapolated to masked points with EXTRAP/NINENN method (see above); to do so, the masked grid points are first replaced with a predefined value. The required global grid mask must be present in data file masks or masks.nc (see section 7.2).
The generic input line is as follows:
# GLORED operation
$NNBRLAT $NV $NIO $NID
where $NNBRLAT
is as for REDGLO (see REDGLO description above).
The next 3 parameters refer to the EXTRAP/NINENN extrapolation
(see EXTRAP/NINENN description above). The value assigned to
all land points before interpolation is given by amskred in oasis3/src/blkdata.f; as for the $VALMASK in
MASK analysis, it has to be chosen well outside the range of
your field values but not too large to avoid any representation problem.
