Description
Voyager 2 Saturn encounter magnetometer data from the Low Field Magnetometer (LFM) resampled at a 9.6-second sample rate. The dataset includes calibrated magnetic field vector components in Saturn-centered Kronographic (L1) coordinates, measured in nanotesla, with coverage beginning in the solar wind and continuing through at least the first magnetopause crossing. Data was processed by the National Aeronautics and Space Administration, with processing starting on 1988-09 21.
Use Cases
Modeling Saturn's magnetospheric structure based on radial, azimuthal, and north/south magnetic field components.
Analyzing magnetic field variability and noise levels based on RMS values for Br, Bt, and Bn.
Calculating magnetic latitude and longitude based on the delta and lambda columns.
Studying the solar wind-magnetosphere interaction based on data coverage from the solar wind through the magnetopause.
Strengths
Data is calibrated, with a specified noise level of 0.006 nT.
Includes derived parameters like magnetic field magnitude, latitude, and longitude.
Processing level ID is 4, indicating a high level of data refinement.
Sampling parameter resolution is precisely 9.600000 seconds, derived from a 60 ms instrument rate.
Limitations
Maximum sampling parameter is listed as 'UNK' (unknown), limiting knowledge of temporal coverage.
Row count and file size are unknown, which may limit suitability assessment.
Column-level documentation is absent; field semantics must be inferred after download.
