|---|
| 15 | ! |
|---|
| 16 | ! Modifications: Aug.2010 EM : use NetCDF90 to load variables (enables using |

|---|
| 22 | ! This subroutine reads from a NetCDF file (opened by the caller) |
|---|
| 23 | ! of "startfi.nc" format. |
|---|
| 24 | ! The various actions and variable read/initialized are: |
|---|
| 25 | ! 1. Check out the number of soil layers (in datafile); if it isn't equal |
|---|
| 26 | ! to nsoil, then some interpolation will be required |
|---|
| 27 | ! Also check if data in file "startfi.nc" is in older format (ie: |
|---|
| 28 | ! thermal inertia was depth-independent; and there was no "depth" |
|---|
| 29 | ! coordinate. |
|---|
| 30 | ! Read/build layer (and midlayer) depths |
|---|
| 31 | ! 2. Read volumetric specific heat (or initialise it to default value) |
|---|
| 32 | ! 3. Read Thermal inertia |
|---|
| 33 | ! 4. Read soil temperatures |
|---|
| 34 | ! 5. Interpolate thermal inertia and temperature on the new grid, if |
|---|
| 35 | ! necessary |
