Subgroup 4c is read only when LSNOW=T. When LSNOW=F, this section<br />

must not be active. To de-activ<strong>at</strong>e, change the delimiters to a<br />

comment marker such as '*'. To activ<strong>at</strong>e, change the delimiters to<br />

an exclam<strong>at</strong>ion point.<br />

Parameters for Snow-Age adjustment to surface albedo<br />

Snow Time-Scale (days) : Number <strong>of</strong> days from last snow when snow becomes dirty.<br />

Albedo Reduction Factor: Reduces albedo when snow becomes dirty.<br />

<strong>The</strong> amount the albedo is reduced is product <strong>of</strong> this<br />

factor and the albedo difference between the surface<br />

with and without snow.<br />
