Lateral boundary conditions (LAM only)

When GEM is run in LAM mode, a set of atmospheric data need to get provided to drive the model at the lateral boundaries. These datasets need to include the following fields:

• Temperature
• Moisture (relative humidity, specific humidity, or dew point temperature)
• Horizontal winds in u- and v-grid(!) direction
• Geopotential (pressure levels: on all levels; model levels: only lowest level)
• Surface pressure
• Condensates (if available; they need to match the condensation scheme used!)

The 3-D fields can be either on model or on pressure levels.
