nest initialization using Noah mosaic_cat option


Hi everyone,

When using the mosaic_cat option with Noah LSM does WRF take into account the type of soil in the nested cell to initialize from parent domain ?
For example if a parent (d01) cell is composed 50% of loam and 50% of sand, let's consider one of the nine d02 cells into which the parent cell is divided. If this d02 cell is composed 100% of sand, is this cell initialized at the temperature (humidity) of the d01 sand tile or is it initialized with an average temperature (humidity) ?

Thank you,

The mosaic option is applied to each individual domain. For the case you described, if the d02 cell is composed 100% of sand, then it is initialized as a sand point. It will not use the average temperature of D01 as its initial data.
