unithickness
- unithickness(lnsp[, levels][, lnsp_code])
- unithickness(lnsp, fs_levels[, lnsp_code])
Computes the pressure thickness in Pa of a list of ECMWF model levels from
lnsp
(logarithm of surface pressure).- Parameters
- Return type
lnsp
must contain an lnsp field, which is identified by its ecCodes paramId. By default the value of 152 is used but it can be overridden by the optionallnsp_code
.The list of target model levels depends on the actual arguments:
if no
fs_levels
is specified the thickness is computed for all the model levels defined by the GRIB header inlnsp
.if
fs_levels
is specified the thickness is computed for all the model levels infs_levels
.if
levels
is specified it defines the list of target model levels whose thickness will be computed.
A missing value in
lnsp
will result in a missing value in the corresponding place in the output fieldset.
