gcm.py @ 361

Last change on this file since 361 was 361, checked in by acolaitis, 14 years ago

PYTHON.

Added zrecast capabilites for gcm.py. Interp modes AGL and P are working. Adding more is not difficult.
One should make sure that his zrecast.e is up to date and in his $PATH.

Note: we could also use f2py to compile a python module... However, most people do have zrecast in their path.

Note2: When using inter-file comparisons, such as field differences, one should make sure to use zrecast (or -i with gcm.py) to
make sure that operations are done at the same altitudes ! (levels in different simulations a priori do not represent same altitudes)

Note3: zrecast has been modified in previous commit to work with teta instead of temp, if needed.
