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.

The Space Environment Monitor (SEM) Magnetometer (MAG) instrument onboard the GOES satellite series measures the magnitude and direction of the Earth's ambient magnetic field in geosynchronous orbit. This data collection includes Reprocessed Level-1b and Level-2 SEM/MAG data from GOES 8-15. The data are enhanced to science quality from the original operational archive. Enhancements include the highest temporal cadence (2Hz), recomputed means, corrected calibration parameters, updated quality flagging, vector measurements in geophysically relevant coordinates, and full ephemeris information. The data were produced by NOAA’s National Centers for Environmental Information (NCEI) and archived by NOAA's Comprehensive Large Array-Data Stewardship System (CLASS).

The GOES-R spacecraft includes a pair of boom-mounted fluxgate magnetometer instruments which operate simultaneously to obtain measurements of the geomagnetic field. The Magnetometer Subsystem supports the following mission objectives: 1) Map the space environment that controls charged particle dynamics in the outer region of the magnetosphere, 2) Measure the magnitude and direction of the Earth's ambient magnetic field in three orthogonal directions in the geosynchronous equatorial orbit, 3) Determine general level of geomagnetic activity, and 4) Detect magnetopause crossings, storm sudden commencements, and substorms. These MAG Level 2 (L2) data include several different products: high-resolution magnetic field readings in multiple coordinate systems; one--minute magnetic field averages in multiple coordinate systems; magnetic field deviation from quiescent state; and the geo-magnetopause crossing location and identification of when geo-magnetopause crosses satellite paths. Data are in netCDF-4 format.

The Space Environment In-Situ Suite (SEISS) Instrument Engineering Telemetry Data file contains data used to monitor and evaluate the health and performance of the sensor suite. This data is transmitted to the ground in raw digital counts, and subsequently converted into physical units by the ground system. All the data pertains to the temperature of components in the sensor suite. Primarily, this includes temperatures for the telescopes and other sensing components. The SEISS Calibration Data file contains data used to support the generation of EHIS, MPS-LO, MPS-HI, and SGPS Level 1b products, and monitor and evaluate the health and performance of the sensor suite. This file contains derived level 1b calibration parameters including raw sensor count rates, valid raw sensor count data percentages, and dead-time and contamination correction factors needed for the production of all the SEISS products.

The Solar Ultraviolet Imager (SUVI) Instrument Engineering Telemetry Data file contains data used to support the generation of SUVI Level 1b products, and monitor and evaluate the health and performance of the instrument. This data is transmitted to the ground in raw digital counts, and subsequently converted into physical units by the ground system. Most of the data pertains to the temperature of components in the instrument. This includes temperatures for the guide telescope, door mechanism, supporting structure, shutter, aperture, filter wheels, mirrors, electronics, and CCD. CCD bias voltages are also included. The SUVI Dark Frame Data file contains an image produced by the SUVI with the camera’s shutter closed. A dark frame measures the inherent bias and noise in the camera electronics, and is used to identify, track, and monitor permanently bad pixels. Dark frames are collected in the operational imaging epoch of the SUVI, and support the radiometric correction of the solar imagery products. Up to ten dark frames are used to support of radiometrically correcting individual solar images. The SUVI Miscellaneous Frame Data file contains a special image produced by the SUVI to support several calibration related activities. Specific types of images include glass, flat-field, and light transfer curve.

The Geostationary Lightning Mapper (GLM) Instrument Engineering Telemetry Data file contains data used to monitor and evaluate the health and performance of the GLM. This data is transmitted to the ground in raw digital counts, and subsequently converted into physical units by the ground system. Some of the data pertains to the temperature of components of the GLM. This includes temperatures for the CCD pedestal, focal plane array, and filtering temperatures. Other telemetry includes the number of events rejected by instrument on-board processing filters and background image count statistics. The GLM Background Image Data file contains the average background value in digital counts for pixels in the instrument’s CCD. The averaging is performed by the instrument prior to downlink. This data is used to support the generation of GLM Level 1b products.

The GOES-R Magnetospheric Electrons and Protons: Medium and High Energy (MPSH) Product consists of fluxes of medium and high energy electrons and protons derived from in situ measurements of electron and proton count rates. The Magnetospheric Particle Sensor High (MPS-HI) makes these measurements. MPS-HI consists of ten solid state telescopes, five for electrons and five for protons, that define a 170-degree fan-like field-of-regard in the north-south plane. Differential and integral electron fluxes are reported at eleven energy bands from each electron telescope. Ten of the energy bands are evenly spaced logarithmically spanning from 50 keV to 4 MeV with differential electron flux being reported. The eleventh energy band collects electrons with energies greater than 2 MeV with electron integral flux being reported. In addition, differential proton fluxes are reported at eleven energy bands from each proton telescope. The eleven proton energy bands are evenly spaced logarithmically and range from 80 keV to 12 MeV. In addition, the product contains ionizing radiation doses in two energy deposition ranges, 50 keV to 1 MeV (low linear energy transfer, LOLET) and 1 MeV to 50 MeV (high linear energy transfer, HILET). The product also contains processing and data quality metadata, satellite state and location information, and data required for the generation of level 2 products. Measurement resolution is one second. NOAA's National Centers for Environmental Information (NCEI) has created these daily files by aggregating the official L1b files produced by the GOES-R Ground System. The granular L1b files each span 30 seconds of observations.
