| 31 | ! Note: This is the FLEXPART_WRF version of subroutine gridcheck. * |
---|
| 32 | ! The computational grid is the WRF x-y grid rather than lat-lon. * |
---|
| 33 | ! * |
---|
| 34 | ! Calculation of turbulent particle trajectories utilizing a * |
---|
| 35 | ! zero-acceleration scheme, which is corrected by a numerically more accurate * |
---|
| 36 | ! Petterssen scheme whenever possible. * |
---|
| 37 | ! * |
---|
| 38 | ! Particle positions are read in, incremented, and returned to the calling * |
---|
| 39 | ! program. * |
---|
| 40 | ! * |
---|
| 41 | ! In different regions of the atmosphere (PBL vs. free troposphere), * |
---|
| 42 | ! different parameters are needed for advection, parameterizing turbulent * |
---|
| 43 | ! velocities, etc. For efficiency, different interpolation routines have * |
---|
| 44 | ! been written for these different cases, with the disadvantage that there * |
---|
| 45 | ! exist several routines doing almost the same. They all share the * |
---|
| 46 | ! included file 'includeinterpol'. The following * |
---|
| 47 | ! interpolation routines are used: * |
---|
| 48 | ! * |
---|
| 49 | ! interpol_all(_nests) interpolates everything (called inside the PBL) * |
---|
| 50 | ! interpol_misslev(_nests) if a particle moves vertically in the PBL, * |
---|
| 51 | ! additional parameters are interpolated if it * |
---|
| 52 | ! crosses a model level * |
---|
| 53 | ! interpol_wind(_nests) interpolates the wind and determines the * |
---|
| 54 | ! standard deviation of the wind (called outside PBL)* |
---|
| 55 | ! also interpolates potential vorticity * |
---|
| 56 | ! interpol_wind_short(_nests) only interpolates the wind (needed for the * |
---|
| 57 | ! Petterssen scheme) * |
---|
| 58 | ! interpol_vdep(_nests) interpolates deposition velocities * |
