Snow Measurement

• Airborne SWE Measurement Theory

  • Airborne SWE measurements are made using the following relationship:

Where:

C and C0 = Uncollided terrestrial gamma count rates over snow and dry, snow-free soil,

M and M0 = Percent soil moisture over snow and dry, snow-free soil,

A = Radiation attenuation coefficient in water, (cm2/g)
