Hello Takuya,

Thanks for your proposals. Please see below for my responses.

I think the following names are all fine as proposed, including the
definitions you have given:
>
> #standard name, long name, units
> canopy_temperature, Temperature of canopy, K
where temperature is the bulk temperature of the canopy.

> surface_brightness_temperature, Brightness temperature at surface, K
where surface means the lower boundary of the atmosphere.

> volume_fraction_of_condensed_water_in_soil_pore, Soil wetness, 1
defined as
> the volume ratio of soil condensed water (liquid and ice) to porosity
of
> the soil.

> tendency_of_specific_humidity_due_to_large_scale_precipitation,
Tendency

There is one other proposal:
>
> condensed_water_per_unit_volume_in_soil, Condensed water in unit
volume of
> soil, kg m-3
defined as
> the amount of condensed water (liquid and ice) contained in unit
volume of
> soil (not content in soil layer but amount per unit volume).

For this name I would suggest we use
mass_concentration_of_condensed_water_in_soil. "Mass concentration" is
used in one or two other standard names and means "mass per unit volume"
which is exactly as you describe. Is that OK?

Best wishes,
Alison
