PO.DAAC Cloud Data Ecosystem – Part 1: Search, Access and Services

Presented at the GHRSST XXIII international science team meeting, 27 June-1 July 2022, online and in-person (Barcelona). #GHRSST23

Short abstract

PO.DAAC has pioneered the NASA earth data cloud migration to the Earthdata Cloud (Amazon Web Service – AWS) since January 2021. Today, almost all of the GHRSST datasets archived at PO.DAAC have been successfully migrated. The migration effort includes not just the datasets, but also the access tools/services, together forming the new PO.DAAC Cloud (POCLOUD) data ecosystem – new cloud paradigm, which brings challenges to the users with many new features and opportunities. A new Cloud Data page on PO.DAAC website has been created as an collective information center to help guide data users in discovering, accessing, and utilizing cloud data. In the new cloud paradigm, the traditional PO.DAAC data search web portal will be preserved to continually serve as the main data discovery platform. In addition, NASA has designed a new Earthdata search portal for discovering the earth science datasets across 12 NASA data centers. To access the POCLOUD data, most of the on-premise tools and services are (will be) made available except the PO.DAAC Drive, which will be retired after the cloud data migration. Currently, the data direct download (https), OPeNDAP, the Level 2 subsetting tool HiTIDE,  and the visualization tool SOTO have been added to POCLOUD datasets. A collection of Harmony APIs, which are a common family of services discovering and accessing the Earth observation data from different NASA data centers, are also made available to most POCLOUD data, including services for subsetting, Zarr reformatting, and regridding. Users are encouraged to find helpful tutorials, demos and recipes from Cloud Data page, such as, the powerful and efficient data subscriber script, tutorials on OPeNDAP, Amazon s3 bucket direct access, and cloud data applications.
