1. Introduction
1.1 Scope
This document outlines a detailed plan for all aspects of Operation IceBridge data management throughout its project lifecycle until 2020. Its content is applicable to all data providers and all data sets unless specific exceptions are made.
1.2 Mission Description
The Operation IceBridge mission, initiated in 2009, collects airborne remote sensing measurements to bridge the gap between NASA’s Ice, Cloud and Land Elevation Satellite (ICESat) mission and the upcoming ICESat-2 mission. Operation IceBridge survey areas include the Greenland and Antarctic ice sheets, Canadian ice caps, Alaskan glaciers, and sea ice in the Arctic and Southern oceans.
Operation IceBridge combines multiple instruments to map ice surface topography, bedrock topography beneath the ice sheets, grounding line position, ice and snow thickness, and sea ice distribution and freeboard. Data from laser altimeters and radar sounders are paired with gravimeter, magnetometer, mapping camera, and other data to provide dynamic, high-value, repeat measurements of rapidly changing portions of land and sea ice.

3.8.1.5 Scanning Lidar
This is a multi-beam, scanning photon-counting lidar built by Sigma Space. It images the surface below the aircraft with one hundred laser beamlets. This system is mechanically scanned in a swath either side of the flight path. A one hundred channel photon counting receiver captures return photons and records time of flight and time tag data allowing a three-dimensional reconstruction of the surface. At a survey altitude of 800 m, swath width is around 400 m.

3.10.1 Instruments and Science Data Products
3.10.1.1 WISE
This sounder uses 120-mlong wavelengths to penetrate past rough ice surfaces, voids, water pockets, water-filled cracks, and temperate ice (ice at the in-situ-pressure melting point) before they are reflected by the interface between ice and the glacier bed. This makes the system well suited for the study of outlet glaciers with challenging internal structure, i.e. highly absorptive or scattering heterogeneities associated with the presence of liquid water pockets within the ice.

4. Data Stewardship
The NSIDC DAAC, with support from the ESDIS Project, is responsible for ingest, archive, and distribution of all IceBridge data products. This includes Level 0 data (where specified), higher level products, ancillary data, metadata, algorithm source code, documentation, and other information in accordance with EOS Data and Information System (EOSDIS) archive policies. Responsibilities also include the distribution of the above-mentioned products to users in accordance with the IceBridge mission and EOSDIS data distribution policies. Public release of these data shall conform to the NASA Earth Science Data and Information Policy, which can be found at: https://science.nasa.gov/earth-science/earth-science-data/data-information-policy/”>science/earth-science-data/data-information-policy/.
Previously, NSIDC used an abbreviated ingest process (“fasttrack”) which circumvented the approved NASA processes and standards in order to make data available as quickly as possible, and enabled data providers to deliver data with minimal metadata and documentation. That process will no longer be available. All data will be delivered to NSIDC using the steps described below unless ESDIS and the IceBridge Project Science Office grant specific exceptions.
In order to ensure that NASA’s expectations for data preservation and usability are met, NSIDC may delay publication of any data set that is not delivered with full documentation (as specified in the NASA documentation content specifications) or that does not meet delivery requirements.
4.1 Acceptance of New Data Sets
Before a new IceBridge data product is sent to the NSIDC DAAC, the following steps must first be implemented:
4.1.1 A description of the data product in question will be documented by the provider and sent to the Operation IceBridge Project Science Office, the ESDIS Project, and the NSIDC DAAC. This description will include:
- A description of the science content of the data product and its relevance to Operation IceBridge science requirements
- Level of product (0-4)
- Expected data volume (per life of mission)
- Current archive location
4.1.2 Review by ESDIS and the Project Science Office. Any new product that is proposed will be reviewed by ESDIS and the Operation IceBridge Project Science Office to make sure that the product is scientifically relevant, within the scope of the Operation IceBridge mission objectives, and that sufficient resources are available to support it. An evaluation of its current archive status will be made to determine if the product can be “brokered”, or linked, from its existing location rather than ingested into NSIDC’s data archive. Only when data is judged to be safely archived and sufficiently documented will a brokering arrangement be considered. In the case of brokering, NSIDC enables discovery of the data through appropriate links, but bears no further responsibility to the data.
4.1.3 Create appropriate short names and long names for each data product. NSIDC will do this in conjunction with the provider.
4.1.4 ESDIS will update this Data Management Plan.
4.2 Data Submission Process
This process applies to all IceBridge data sets that are not currently archived in NSIDC’s Earth Core System (ECS) system (unless ESDIS and the IceBridge Project Science Office grant an exception). As of March 2013, only UARC has been granted said exception for the DMS data sets.
As part of each new submission, each provider must provide NSIDC with the information required to create and validate an Earth Science Data Type (ESDT) that defines the structure of the data set. Once created, the ESDT is maintained as long as the data set structure does not change.
The provider is responsible for providing NSIDC with information required for any updates to the ESDT and notifying NSIDC if changes are planned to the content or structure of the data set. The ESDT must be consistent with the content of expected data delivery.
In order to efficiently ingest data into NSIDC’s ECS system, ESDIS has created (through its ECS contractor) a generic tool for creation of necessary metadata and associated files. This tool, called “SIPSMetGen”, is given to each provider along with associated configuration files for its correct operation.
Details of how to run the SIPSMetGen tool will be included with the tool package. Details of how data ingestion to NSIDC will now work using SIPSMetGen can be found in the IceBridge Science Investigator-led Processing System (SIPS) Operational Concept Document located at:
https://n5eil01u.ecs.nsidc.org/PullDir/OIB_SIPSMetGen/latest/SIPSMetGen_2.0.1_UserGuide.pdf.
The providers retain full responsibility for data and control over metadata quality. This process is simply a mechanism for automated ingest to NSIDC.
4.2.1 Before the first submission, the provider is responsible for performing integration testing with NSIDC to ensure that data will routinely be ingested successfully without excessive manual intervention by NSIDC’s Operations staff.
4.2.2 The provider is responsible for running the SIPSMetGen tool and creating the necessary metadata and Product Delivery Record (PDR) files before each data submission. After receipt of ingest status notices from ECS, the provider (with support from NSIDC and the ECS contractor) is responsible for all error correction and re-delivery.
4.3 Naming Conventions
Science data files and their associated supporting files (such as browse, quality assurance, preliminary metadata (“premet”), and spatial files) must use a standard naming convention. A file and its associated files should use the same name; the file extension distinguishes the data file from the associated files. File names should include the ESDT shortname, date and time of data collection, version identification, and any additional information that might be needed to uniquely identify the data file.
Example, for ATM L1B data:
Data file: ILATM1B_V01_04212010_04452366_A.h5
Premet file: ILATM1B_V01_04212010_04452366_A.premet
Spatial file: ILATM1B_V01_04212010_04452366_A.spatial
