|
|
! "regr_coefoz" stands for "regrid coefficients ozone". |
| 16 |
|
|
|
| 17 |
|
|
! This procedure reads from a file parameters for ozone |
| 18 |
|
|
! chemistry and regrids them for LMDZ. |
| 19 |
|
|
! The input fields depend on time, pressure level and |
| 20 |
|
|
! latitude. |
| 21 |
|
|
! We assume that the input fields are step functions |
| 22 |
|
|
! of latitude. |
| 23 |
|
|
! Horizontal regridding is made by averaging on latitude, with a |
| 24 |
|
|
! cosine of latitude factor. |
| 25 |
|
|
! The target horizontal LMDZ grid is the "scalar" grid: "rlonv", "rlatu". |
| 26 |
|
|
! The values of "rlatu" are taken to be the centers of intervals. |
| 27 |
|
|
! The target vertical LMDZ grid is the grid of mid-layers. |
| 28 |
|
|
! The input latitude values are different from the latitude values |
| 29 |
|
|
! of the LMDZ "scalar" grid. |
| 30 |
|
|
! The input data does not depend on longitude, but the pressure |
| 31 |
|
|
! at LMDZ mid-layers does. |
| 32 |
|
|
! Therefore, the values on the LMDZ grid do depend on longitude. |
| 33 |
|
|
! The regridded fields are written to a file. |
| 34 |
|
|
|
| 35 |
|
|
! We assume that in the input file the latitude is in degrees |
| 36 |
|
|
! and the pressure level is in hPa, and that both are strictly |
| 37 |
guez |
4 |
! monotonic (as all NetCDF coordinate variables should be). |
