Alaska Satellite Facility Distributed Active Archive Center

Below is the EULA that defines data access at NASA’s Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC).

ASF Terms of Service

ASF DAAC data products are available to data users registered with the NASA User Registration System (URS). Agreements between ASF and some data partners require limited restrictions on specific data collections and are defined here.

Terms of Service Contents

  • International Polar Year (IPY) Data Agreement
  • ALOS/PALSAR/AVNIR-2 and ALOS-2 ScanSAR data products usage conditions
  • ALOS PALSAR RTC Product License
  • Sentinel-1 Data License
  • ERS-1 and ERS-2 Data License

International Polar Year (IPY) Datapool

The IPY Datapool is fully accessible to users agreeing to the IPY Data Agreement restrictions. By agreeing to the IPY TOC, you are agreeing to the terms which apply to the IPY Data Pool accessible through ASF, which are listed as Conditions here;

Condition 1 – I agree to use the Data for peaceful purposes only.

Condition 2 – I agree to use the Data for noncommercial use only. No commercial use is allowed of the data or any products derived from these data. I also understand that a value-added product derived from the data products received from ASF can only be freely distributed by me if it is in such a form that the original backscatter values cannot be derived from it.

Condition 3 – The data will not be reproduced or distributed to any other parties, except that they may be shared among named members of my research team (co-investigators). I will be responsible for compliance with this condition for the data I obtain from ASF. Furthermore, I am responsible for compliance to these agreement terms by members of my research team with whom I share these data.

ALOS/PALSAR/AVNIR-2 and ALOS-2 ScanSAR data products usage conditions
