ILRS Virtual World Tour 2020 second circular
(25 September 2020)

In place of the planned Workshop this November, the ILRS wanted to take the opportunity to try something different and look in detail at a selection of stations in the global network. The online 'Virtual World Tour', to be held November 2-6, 2020, will visit 5 stations in 5 days, stopping at:

  • Graz, Austria
  • Greenbelt MD, USA
  • Simosato, Japan
  • Yarragadee, Australia
  • Zimmerwald, Switzerland

Each two-hour session will consist of an introductory presentation about the station followed by a tour of the site highlighting instrumentation, software, safety, automation, operations, as well as current issues and future plans. These tours will include a mixture of pre-recorded and live presentations with an opportunity for questions.

More information about the workshop can be found on the website:

NASA Earth Science Data and Services Survey for 2020
(23 September 2020)

Dear Colleagues,

Recently, some of you may have received an email from the CFI Group on behalf of NASA. This message asked you to complete a survey for users of NASA Earth science data and services, which includes the Crustal Dynamics Data Information System (CDDIS). The CDDIS is one of twelve NASA Earth Observing System Data and Information System (EOSDIS) science data centers evaluated by this survey. The purpose of this survey is to help NASA and the DAACs assess customer satisfaction and improve future services. Suggestions from past surveys have been implemented to improve the tools and services offered by the CDDIS.

Please participate! Your feedback affects our future performance and helps to identify science needs. You will be able to take the survey for each DAAC you use. This is your opportunity to influence the priorities of the DAACs, including CDDIS.

If you did not receive a survey and wish to complete one or know of someone who uses CDDIS and/or EOSDIS data and services who did not receive a survey, please contact

surveyhelp@cfigroup.com.

The American Customer Satisfaction Index (ACSI) is the only national cross-industry measure of customer satisfaction in the United States. NASA commissioned the CFI Group, an independent research and consulting organization, to conduct a brief survey to rate the products and services NASA currently provides from NASA's EOSDIS data centers. Please consider responding to this survey; your input will help us to better serve our user community.

Presentations of these results given to NASA Earth science are available at:

https://earthdata.nasa.gov/about/system-performance/american-customer-satisfaction-index-reports

Thank you in advance to all of you who are willing to spend a few minutes to complete the survey.

ILRS Workshops scheduled for 2020 and 2021 postponed
(14 July 2020)

As the ILRS community continues to deal with the impacts from the global coronavirus outbreak, the ILRS and the local organizers in Kunming have concluded that it is no longer possible to hold the 22nd International Workshop on Laser Ranging in October 2020 as planned. The ILRS Governing Board, in consultation with our colleagues in Kunming, has decided that we will delay this workshop until the fall of 2021; final dates for the event will be announced soon. Furthermore, the ILRS and UNSA will postpone the next ILRS Technical/Specialty Workshop, to be held in Arequipa Peru, until the fall of 2022.

We will keep the community informed of additional details as soon as practical.

Invitation to the official launch of the new Earthdata User Forum
(18 February 2020)

You are invited to the official launch of the new Earthdata User Forum on Tuesday, February 25, 2020 at 11AM for a demonstration. The Webex will include an overview of the site, as well as a demonstration of data users' and NASA Distributed Active Archive Centers subject matter experts' interaction about general questions, research needs and data applications.

The Atmospheric Science Data Center (ASDC), in cooperation with ESDIS, has created a new ESDIS Cross-DAAC Forum for Earth Science knowledge discovery and distribution. Currently, ASDC, Crustal Dynamics Data Information System (CDDIS), Goddard Earth Science Data and Information Services Center (GES DISC), Global Hydrology Resource Center (GHRC), and Land Processes DAAC (LP DAAC) are participants. The Earthdata User Forum offers Earth Science explorers the opportunity to search answers to Earth Science questions across NASA DAACs and Missions.
