Last change on this file since 4678 was 4619, checked in by yann meurdesoif, 11 months ago

Suppress usage of preprocessing key CPP_XIOS.
Wrapper file is used to suppress XIOS symbol when xios is not linked and not used (-io ioipsl)
The CPP_XIOS key is replaced in model by "using_xios" boolean variable to switch between IOIPSL or XIOS output.

30SUBROUTINE regr_horiz_time_climoz(read_climoz,interpt)
31!
32!-------------------------------------------------------------------------------
33! Purpose: Regrid horizontally and in time zonal or 3D ozone climatologies.
34!   * Read ozone climatology from netcdf file
35!   * Regrid it horizontaly to LMDZ grid (quasi-conservative method)
36!   * If interpt=T, interpolate linearly in time (one record each day)
37!     If interpt=F, keep original time sampling  (14 months).
38!   * Save it to a new netcdf file.
39!-------------------------------------------------------------------------------
40! Remarks:
41!   * Up to 2 variables treated: "tro3" and "tro3_daylight" (if read_climoz=2)
42!   * Input fields coordinates: (longitudes, latitudes, pressure_levels, time)
43!   * Output grid cells centers coordinates given by [rlonv,] rlatu.
44!   * Output grid cells edges   coordinates given by [rlonu,] rlatv.
45!   * Input file [longitudes and] latitudes given in degrees.
46!   * Input file pressure levels are given in Pa or hPa.
47!   * All coordinates variables are stricly monotonic.
48!   * Monthly fields are interpolated linearly in time to get daily values.
49!   * Fields are known at the middle of the months, so interpolation requires an
50!     additional record both for 1st half of january and 2nd half of december:
51!     - For a 14-records "climoz.nc": records 1 and 14.
52!     - For 12-records files:
53!       record 12 of "climoz_m.nc" if available, or record 1  of "climoz.nc".
54!       record 1  of "climoz_p.nc" if available, or record 12 of "climoz.nc".
55!   * Calendar is taken into account to get one record each day (not 360 always).
56!   * Missing values are filled in from sky to ground by copying lowest valid one.
57!     Attribute "missing_value" or "_FillValue" must be present in input file.
