SECOND ROUND

NASA's Earth Science Data and Information Systems (ESDIS) Standards Coordination Office (ESCO) conducts reviews of proposed standards, practices, and technical information relevant to the ESDIS mission. Documents are reviewed as part of the ESDIS Project's standards process. Approved documents are published and listed on the Earthdata Standards Requirements and References page.

Reviewer comments from the initial review have been addressed and incorporated into the current document status. This follow-up edited version is provided to ensure that initial comments have been adequately addressed and is open to both past and new reviewers. You are invited to review these proposed terms and definitions in the context of your experience with the Earth Observing System Data and Information System (EOSDIS) and cloud-optimized data formats. 

ESCO is conducting a review of Zarr storage specification version 2: Cloud-optimized persistence using Zarr. You are invited to review the document in the context of your experience with Earth science data, for its suitability for operational use.  Your insights will help improve this document, and determine whether it should be adopted as a NASA Convention  for Earth Science data producers.

This review is intended for the community of Earth science data users who may benefit from the adoption of the Zarr cloud-optimized storage format for data access and scientific computing.  A clear understanding of both the advantages and limitations of this format are necessary to best serve these end user communities.  

If approved, these recommendations will serve as a NASA Convention (i.e. a specification in common use among some members of the NASA ESDS community).

If you or your team member can review this document, please send names, email addresses, and Earthdata login usernames to esco-staff@lists.nasa.gov.  The ECSO Staff will add your names as reviewers in the Jama system.  You may also send any questions about the review to the ESCO staff at esco-staff@lists.nasa.gov.
