Subject: RE: GLIMS Update: Global ASTER imaging reprioritization

Dear All,
can I ask how many RCs, like ourselves in Scandinavia, have received very little 
ASTER coverage? Many of us are relying on Landsat-7 because there haven't been 
ASTER acquisitions over our region. It seems to me that there is a need to evaluate 
GLIMS priorities and then assess the tasking needs. For example, I can understand 
that in terms of climate change imaging Scandinavian glaciers may be relatively less 
important than repeat coverage of Greenland glaciers allowing quantitative change 
detection. However, if you want GLIMS to generate an ASTER derived baseline of 
glacier parameters then gobal coverage should be prioritised ahead of repeat 
acquisitions of regions already covered. Just a  thought...
Regards,
Ian
