Ward,

I don't believe that they archive this composite, but I will email them
to make sure.  The unfortunate fact is that _if_ they archive them, then
getting them will probably cost real dollars.

re: looking for a source of GMS imagery

It is.

>What would be gained by stand-alone GMS images?

Higher spatial and temporal resolution.  Also, more bands (wavelength
channels).

>As I remember, they only image the eastern half of Nepal.

I was not aware of this.  I was operating under the assumption that
GMS would cover Nepal well enough to be superior to the composite
that you have been using.

No, I was not aware of this article, but I will certainly check it out
tomorrow.

>Would the data this 
>paper refers to be a source of high-resolution data for Nepal?

Could be.  I'll know more after reading the article.

Got to run..
