|---|
| 127 | we build a possible depths array |
|---|
| 128 | IDL> a=gdept[jpk-1]/(1.*jpi*jpj)*findgen(jpi,jpj) |
|---|
| 129 | We build an array to project on these depths. For the test, |
|---|
| 130 | we build a 3d array whose each vector following z is the depth. |
|---|
| 131 | IDL> arraytest=replicate(1,jpi*jpj)#gdept |
|---|
| 132 | IDL> arraytest=reform(arraytest,jpi,jpj,jpk, /over) |
|---|
| 133 | We test the projection of the depth array on the depth... |
|---|
| 134 | IDL> plt, 1e6*(a-projectondepth(arraytest,a)),/nocontour |
|---|
| 135 | ->null field at 1e-6 pres |
|---|
| 136 | |
|---|
| 137 | verification projecting the temperature of 20°C for example... |
