Changeset 1239 for LMDZ4

Timestamp:

Sep 8, 2009, 11:16:12 AM (15 years ago)

Author:

Message:

Print only defined values of "timeyear" in procedure "limit_netcdf".

Processing of input variable "read_climoz" by procedure "conf_phys"
was broken in revision 1227. Fixed it back (no need for a variable
"read_climoz_omp"; "read_climoz" is OpenMP shared).

Procedure "regr_lat_time_climoz" now takes into account missing values
in the input field.
