precipitation
water depth
what does Lp stand for
atmospheric noise
what does Ls stand for
reflected light
,
,
what does Lb stand for
bottom radiance
why is turbid water more challenging then pure water
because turbid water has a higher suspended solids which causes longer wave lengths.
urban wetlands vs forested wetlands in remote sensng
forest wetlands produce a brownish yellow colour
when would you want to use lidar
shallow /hazardous waters
when should sonar be used
deep waters
what is el nino
trade winds relax in the pacific ocean
