PI Justification
To provide the cryospheric community with updated melting maps over Greenland and
Antarctica and support ongoing scientific projects.
Section 2: From DAAC Product Team/Scientist
Heritage:
Marco Tedesco proposed archival at NSIDC.
DAAC Justification:
Per NSIDC Scientists: Walt Meier, Richard Armstrong
(1) Tedesco provides estimates using different methods, can be beneficial for cross-validation
(2) Tedesco includes Antarctica, while the most closely related data is Greenland only
(3) Tedesco is through 2010, while the most closely related data is through 2007.
(4) Tedesco seems more attentive to updating.
User Working Group, MOUs, requests, other
