I'm trying to understand the total soil moisture change in the first meter of soil. VC gives soil moisture at different depths (let's say in mm), over the depth ranges 0 - 0.1m, 0.1 - 0.4 m, and 0.4 - 1 m. Are the reported mm of soil moisture per meter or per the given depth range?
In other words, if I wanted to know the soil moisture from 0 - 1m, would that be?:
soilmoisture01 + soilmoisture04 + soilmoisture10 =
or
soilmoisture01*(0.1) + soilmoisture04*(0.3) + soilmoisture10*(0.6) =
Thanks!
