Annual NASA Customer Survey Time!

Each year, our users have the opportunity to rate and comment on the data, tools, and services provided by us, the NASA Alaska Satellite Facility DAAC (Distributed Active Archive Center). This customer satisfaction survey is conducted by the CFI Group on behalf of NASA, and you may have already received, or will soon receive, an invitation from them with a link to the survey.

Please take time to complete the survey — it doesn’t take long. The feedback you provide is very important to us at ASF and we want to hear about your particular experiences. Your comments, suggestions, and criticisms are extremely valuable as we plan for future development!

If you do not receive a survey in your email by next week, you can request that a link to the survey be sent to you by contacting the CFI Group at [email protected].
