Due to a software issue at the SMAP Science Data System (SDS), SMAP products cannot be produced automatically. This may affect the production of the Level 1-4 products and lead to a slight delay in the data delivery. We apologize for any inconvenience; a patch to fix the issue is forthcoming.
Welcome to the new nsidc.org! To get acquainted with what's changed, read our spotlight article: NSIDC.org website: New look and new features.
Please note that we are in a beta launch of this website. During the beta phase, our website search may act unpredictably until the website stabilizes.
