Polar TIMAS: Ion Upflowing Fluxes and Solar Wind Parameters

H+, O+, He+, and He++ upflowing fluxes and statistical uncertainties from the Polar mission's TIMAS instrument. The summary database includes auxiliary parameters like altitude, magnetic local time, and time-delayed solar wind data from the WIND spacecraft, extending over all altitudes, invariant latitudes, and MLT. Data were processed by the TIMAS science team and used in published research.

Use Cases

• Modeling ionospheric outflow dynamics based on H+, O+, He+, and He++ upflowing fluxes.
• Correlating ion upflow with solar wind conditions based on interpolated IMF and solar wind dynamic pressure parameters.
• Analyzing spatial patterns of ion composition based on coverage across all invariant latitudes and magnetic local time.
• Studying altitude-dependent phenomena using data with 12-second resolution below 4.0 Re and 24-second resolution above.

Strengths

• Includes multiple ion species (H+, O+, He+, He++) with statistical uncertainties.
• Augmented with contextual non-TIMAS data like solar wind parameters, magnetic field vectors, and spacecraft potential.
• Spatial coverage extends over all altitudes, invariant latitudes, and magnetic local time.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a summary and does not contain detailed energy step and pitch angle information for each data point.
