Data Accession NSIDC DAAC UWG Meeting 37, 2019 Donna Scott
What is Data Accession Data Accession at the NSIDC DAAC is the process by which we collect non-EOS assigned data submissions for archival and distribution and review the data submission request through a formal, documented process. NASA/ESDIS Accession Policies Data providers funded under NASA programs are often directed to submit data to a DAAC for archival and distribution . ESDIS guidelines:Data sets must be NASA fundedData sets must be produced in the U.S.Data sets must fit within the cryospheric discipline of the DAAC
Data Accession Roles & Responsibilities DAAC Accession Coordinator Facilitates process, ensures basic requirements met. DAAC Scientist Addresses benefits to science community and DAAC data holdings.Product TeamData management review & recommendations (usability, LoS, etc…)DAAC ManagementReview with DAAC budget in mind, final statement of approval to move forwardESDIS NSIDC DAAC Engineer Reviews request and feedback, provide final approval of accession May seek input from NASA HQ and Cryosphere Program Scientist UWG Select Members (based on expertise) Review the request, affirm or expand upon the assessment performed by the DAAC Scientist. UWG input informs DAAC on further development of documentation, and preparation of potential user questions related to data.
Hands on Review Catania – Submarine terminus face morphology The data were collected using a ship-mounted multibeam that was pointed laterally to image the submarine glacier terminus face.Brodzik - MEaSUREs Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR This data set consists of gridded passive microwave brightness temperature data. This request is for the DAAC to take ownership of the data set, and continue forward processing.The goals of the sessionWorking together to better understand the process and expectations during the UWG reviewCollect UWG review feedback Potentially come out with an overall UWG recommendation for each request that Gina (UWG Chair) can finalize after the meeting. We will evaluate two accession requests. The PI submission and the DAAC review have been completed (part of pre-meeting packet).
Catania UWG Accession SummaryBrodzik In general a positive response to move forward. Considerations for DAAC: With existing papers, and a simple data set, it may not need to be at a standard level of service. Questions for data provider:The data needs more geospatial information providedDAAC Scientist – convert to CSVAcknowledgement that it is a superior product and could supersede existing EASE-Grid data set in PM production.Considerations for DAAC:Think about the messaging of taking on forward processing of a MEaSUREs data set for specific PIBranding and ownership. New data set vs. appending to existing MEaSUREs program data setIn determining the processing schedule (e.g. quarterly), need to consider the availability of using the CU Supercomputer
