Re: Fraction into mm

Respected Wei Huang,
Actually this file (soilw.0-10cm.gauss.2005.nc ) is opened given below when I used it in NCL program  the soil moisture unit indicates in fraction but I want to change it into millimeter(mm). Due to this reason I requested you, thanks for your cooperation.
best regards,
kalim

Respected Wei Huang,
I want to calculate a unit  of mean Daily Volumetric Soil Moisture in mm but it is in fraction. kindly  help me in this regards, it would be great favor. the file is given below.
