Cassini Plasma Spectrometer Data: 1259 Magnetic Boundary Crossing Events

1259 observations from the Cassini Plasma Spectrometer Electron Spectrometer (CAPS ELS) instrument, totaling 128 GB of raw data files. The dataset includes labeled events for bow shock and magnetopause crossings, created by C. M. Jackman at the University of Southampton. It provides scripts for downloading data from NASA's Planetary Data System and for visualizing the labeled events.

Use Cases

• Detecting magnetopause crossing events based on labeled transition times.
• Identifying bow shock crossing events based on labeled transition times.
• Visualizing plasma spectrometer time-series data alongside event labels using the provided plotting script.
• Filtering data to exclude known data-gap or unreliable data events based on provided labels.

Strengths

• Includes 1259 distinct observational events from the CAPS ELS instrument.
• Provides 128 GB of raw instrument data files for detailed analysis.
• Offers pre-processed labels categorizing events into bow shock, magnetopause, data-gap, and unreliable data classes.
• Supplies a Python plotting script to visualize the data and labels together.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• The plotting script requires Python 2.7, which is a deprecated version.

Provenance

NASA's Planetary Data System (PDS) and processing by the dataset author.

Collection Method

Raw data files downloaded from PDS; crossing event labels derived from processing a published table.
