regr_horiz_time_climoz_m.f90 @ 5408

Last change on this file since 5408 was 5353, checked in by yann meurdesoif, 2 weeks ago
Nvidia compiler has some difficulties to compile correctly some complex array constructor. This commit decompose it the several phases in order to achieve the compilation. Please Lionel and David, have a look to this in order to validate. Probably, in future, when compiler heuristic will be improved, this commit can be reversed. YM

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.
