Also, regarding units. Some measures of units are automatically
converted when working with coordinates; for instance a variable
with an on axis that has units of meters can be regridded to an
axis with units of meters and Ferret/PyFerret will handle the
conversion. And in the horizontal directions, longitude/latitude
are handled with areas computed on the globe, and calendar time is
converted whether the units are seconds, days, etc. Other units
are allowed but would not be converted. So that's all that this
message about units is telling us:
*** NOTE: (fyi) units are not subject to auto-conversion: PA

I think b*ps inherits all dimensions:

PS Surface Air Pressure 1:192
1:96 ... 1:120
So, p has dimension 192 x 96 x 95 x 120 and is not
suitable to define an axis.
It should be something like:
let zval = z[gz=B]
define axis/z/depth/unit="Pa" pax=zval
(depth means posive down, hopefully :-) not sure)
Best,

Hi,
Following may give you some hints :
(1) Is pressure unit allowed ? (I think 'K' means only
depth is allowed in distance unit )
(2) In _expression_ "let P = ap+(b*ps)" . b*ps is
'missing data' everywhere. Because there are no common valid
points in 3 D which can give answer. (missing data * good
data = "" data)
^ This may not solve problem , but will give you path to
solve.

Dear all,
I have been trying to define new vertical axis
for my data.
However, I am getting following error in ferret.
AP vertical coordinate formul
... ... 1:95 ...
B vertical coordinate formul
... ... 1:95 ...
PS Surface Air Pressure
1:192 1:96 ... 1:120
AP_BNDS vertical coordinate formul 1:2
... 1:95 ...
B_BNDS vertical coordinate formul 1:2
... 1:95 ...
CL Cloud Area Fraction
1:192 1:96 1:95 1:120
define axis/from_data/z/unit="Pa"
pressure_axis=P[k=1:95]
*** NOTE: (fyi) units are not
subject to auto-conversion: PA
**ERROR: improper grid or axis definition:
data for DEFINE AXIS/FROM_VARIABLE is ambiguous
define axis/from_data/z/unit="Pa"
pressure_axis=P[k=1:95]
Command file, command group, or REPEAT

Am I doing it right way? Or is it not possible to
define axis this way?
Regards,
Vivek
