The purpose of this page of the CDDIS web site is to post new items, activities, data sets, etc. of interest to the CDDIS user community. Users should also consult the list of upcoming meetings of interest to the space geodesy community.
NASA Earth Science Data and Services Survey for 2010 (26-Aug-2010):
IIn the next few days, many users of the CDDIS will receive an email from CFI Group on behalf of NASA. This message will ask you to complete a survey of users of NASA Earth science data and services, which includes the CDDIS. The purpose of this survey is to help NASA and the data centers assess customer satisfaction and improve future services.
The American Customer Satisfaction Index (ACSI) is the #1 national economic indicator of customer satisfaction. Over 70 U.S. Federal Government agencies have used the ACSI to measure more than 120 programs/services. The survey is being conducted by CFI Group under contract with the Department of Interior's Federal Consulting Group, Executive Agent in government for the ACSI. Please consider responding to this survey; your input will help us to better serve our user community.
Results from the 2009 survey are available online at http://www.theacsi.org/ (under ACSI RESULTS > Government Results Archive). In addition, presentations on these results given by NASA Earth science are available at: http://esdis.eosdis.nasa.gov/ (under About EOSDIS > Key Science System Metrics).
Thanks in advance to all who are willing to spend a fewminutes to complete the survey.
CDDIS Computer System Upgrade (08-Jun-2010)
The CDDIS archive will be unavailable starting June 21 at 10:00 EDT (14:00 UTC) for approximately 24 hours (however, as we all know, unforeseen problems could cause a longer outage). At that time, the system will be shut down in preparation for operations to transition to a new server environment. When the new systems are operational, users will continue to access host cddis.gsfc.nasa.gov through anonymous ftp and http and see the same archive structure. However, the IP number for the CDDIS host WILL CHANGE. Users should use the HOST NAME cddis.gsfc.nasa.gov and NOT THE IP NUMBER in their automated file retrieval scripts to the CDDIS.
Groups who submit data and products to CDDIS will need to update their procedures to use host cddisin.gsfc.nasa.gov. These groups should have already received messages from me about this transition and should have supplied the IP numbers of any hosts they use to push files to CDDIS; if you have not contacted me with this information, you WILL NOT be able to deliver ANY DATA OR PRODUCT FILES after the transition. Therefore, please send me an email as soon as possible to coordinate the exchange of IP information. We will send a message to the community when data/products suppliers can being pushing files to the CDDIS host cddisin.gsfc.nasa.gov; this process may begin prior to the availability of the CDDIS archive to general users.
We hope for a smooth transition to our new computer system on June 21/22 and ask your cooperation in preparing your software to use the new incoming server. We will keep you posted as we implement the new system and when we are up for operations. Please contact me if you have any questions

Carey E. Noll, The Crustal Dynamics Data Information System: A resource to support scientific analysis using space geodesy, Advances in Space Research, In Press, Corrected Proof, Available online 18 January 2010, ISSN 0273-1177, DOI: 10.1016/j.asr.2010.01.018.
DAAC Annual Article Featuring CDDIS Data Published (22-Feb-2010)
A feature article, "A snag in space-time", has recently been published discussing how astrophysicists use Earth science satellites (particularly SLR data available through the CDDIS) to explore general relativity. The article is part of the 2009 issue of Sensing Our Planet: NASA Earth Science Research Feature, an annual publication of the Earth Observing System Data and Information System (EOSDIS).
