Mike,
Given the correct sign of the input topography, it could be that the input
files are not "Big Endian" and r4/r8 is mis-matched or that they are correct
but the compile options are wrong and expecting "Little endian". As a rule
we work in big endian. The readbinaryprec parameter (check it's name in
set_defaults.F) controls whether the model reads real*4 or real*8.
I'm cc'ing this to mitgcm-support at mitgcm.org since I'm out of touch for a
week. Jean-Michel knows the R_low businesss best since he wrote it.

Subject: another problem
Hi Alistair,
Sorry to say that I am still having a problem getting the
model running. The first sign of trouble seems to be in
the R_low array:
(PID.TID 0000.0001) MDSREADFIELD: opening global file: topog.bin rlow 1
-5.4765625 rlow 2 -5.4765625 rlow 3 -5.4765625 (PID.TID 0000.0001) //
=======================================================
(PID.TID 0000.0001) // Field Model R_low (ini_masks_etc) at
iteration 1
(PID.TID 0000.0001) // CMIN = 1.000000000000000E+32
(PID.TID 0000.0001) // CMAX = -1.000000000000000E+32
(PID.TID 0000.0001) // CINT = 0.000000000000000E+00
(PID.TID 0000.0001) // SYMBOLS (CMIN->CMAX):
-abcdefghijklmnopqrstuvwxyz+
(PID.TID 0000.0001) // 0.0: .
(PID.TID 0000.0001) // RANGE I (Lo:Hi:Step):( -2: 34: 1)
(PID.TID 0000.0001) // RANGE J (Lo:Hi:Step):( 34: -2: -1)
(PID.TID 0000.0001) // RANGE K (Lo:Hi:Step):( 1: 1: 1)
(PID.TID 0000.0001) //
=======================================================
R_low seems to have reasonable values when read in (my print statements) but
is set to 0.0 for reasons I have not been able to figure out. This then goes
on to set the initial temperature to zeros as well. Any ideas?
At least once I get going, I pretty much leave you alone!
Mike
