---|
| 25 | !------------------------------------------------------------------------------- |
---|
| 26 | ! Purpose: Regrid horizontally and in time zonal or 3D ozone climatologies. |
---|
| 27 | ! * Read ozone climatology from netcdf file |
---|
| 28 | ! * Regrid it horizontaly to LMDZ grid (quasi-conservative method) |
---|
| 29 | ! * If interpt=T, interpolate linearly in time (one record each day) |
---|
| 30 | ! If interpt=F, keep original time sampling (14 months). |
---|
| 31 | ! * Save it to a new netcdf file. |
---|
| 32 | !------------------------------------------------------------------------------- |
---|
| 33 | ! Remarks: |
---|
| 34 | ! * Up to 2 variables treated: "tro3" and "tro3_daylight" (if read_climoz=2) |
---|
| 35 | ! * Input fields coordinates: (longitudes, latitudes, pressure_levels, time) |
---|
| 36 | ! * Output grid cells centers coordinates given by [rlonv,] rlatu. |
---|
| 37 | ! * Output grid cells edges coordinates given by [rlonu,] rlatv. |
---|
| 38 | ! * Input file [longitudes and] latitudes given in degrees. |
---|
| 39 | ! * Input file pressure levels are given in Pa or hPa. |
---|
| 40 | ! * All coordinates variables are stricly monotonic. |
---|
| 41 | ! * Monthly fields are interpolated linearly in time to get daily values. |
---|
| 42 | ! * Fields are known at the middle of the months, so interpolation requires an |
---|
| 43 | ! additional record both for 1st half of january and 2nd half of december: |
---|
| 44 | ! - For a 14-records "climoz.nc": records 1 and 14. |
---|
| 45 | ! - For 12-records files: |
---|
| 46 | ! record 12 of "climoz_m.nc" if available, or record 1 of "climoz.nc". |
---|
| 47 | ! record 1 of "climoz_p.nc" if available, or record 12 of "climoz.nc". |
---|
| 48 | ! * Calendar is taken into account to get one record each day (not 360 always). |
---|
| 49 | ! * Missing values are filled in from sky to ground by copying lowest valid one. |
---|
| 50 | ! Attribute "missing_value" or "_FillValue" must be present in input file. |
