Abstract
A potentially operational snow mapping scheme applicable
to areas of temporary snow cover (e.g. UK) using daily NOAA AVHRR
imagery for the production of weekly composite snow area estimates
is presented. This technique is based upon an unsupervised multispectral
classification of AVHRR channels allowing snow/cloud and
snow type discriminations together with the accurate location of
snowpack margins. Supporting sub-routines have been developed also
for the correction of forest masking and shadowing of the snow by
cloud.
