NOAA GOES-R Series Magnetometer (MAG) Level 0 Data

Metadata Updated: May 31, 2024

This data collection consists of archived GOES-R Series Magnetometer (MAG) Level 0 data from the operational GOES-East and GOES-West satellites. The Geostationary Operational Environmental Satellite-R (GOES-R) series provides continuity of the GOES mission through 2035 and improvements in geostationary satellite observational data. GOES-16, the first GOES-R satellite, began operating as GOES-East on December 18, 2017, and GOES-18 began operating on March 1, 2022, replacing GOES-17 as GOES West in early January 2023. GOES-19 will begin operational service in 2024, replacing GOES-16. MAG measures the magnetic field in the outer portion of the magnetosphere to detect charged particles that can be dangerous to spacecraft and human spaceflight. The Magnetometer Level 0 product contains Consultative Committee for Space Data Systems (CCSDS) science, engineering, and diagnostic telemetry data packets received from MAG. The Level 0 data files also contain orbit and attitude, and eclipse of the sun related and yaw flip state telemetry data packets generated by the GOES spacecraft. Each CCSDS packet contains a unique Application Process Identifier (APID) in the primary header that identifies the specific type of packet, and is used to support interpretation of its contents. Users may refer to the GOES-R Series Product Definition and Users’ Guide (PUG) Volumes 1 (Main) and 2 (Level 0 Products) for Level 0 data documentation. Related instrument calibration data and Level 1b processing information are archived and available for order at the NOAA CLASS website. The MAG Level 0 data files are delivered in a netCDF-4 file format, however, the constituent CCSDS packets are stored in a byte array making the data opaque for standard netCDF reader applications. The MAG Level 0 data files are packaged in daily tar files (data bundles) by satellite for the archive. Recently ingested archive tar files are available for 14 days on a CLASS-hosted anonymous FTP server for users to download. Data archived on tape are available to users by special order through NCEI customer service.
