Vostok Station Vertical Electric Field Measurements 1998-2004

1998-2004 minute-resolution vertical electric field data collected at Vostok Station, Antarctica. The dataset contains calibrated electric field values, including both all-weather and fair-weather filtered measurements. It was produced by a collaboration between the Australian Antarctic Division and Russian Antarctic Expeditions.

Use Cases

• Analyzing diurnal and seasonal patterns in the 'EF-all(V/m)' and 'EF-fair(V/m)' columns.
• Correlating 'DoY' and 'UT Hour' with electric field values to study solar influence on atmospheric electricity.
• Investigating instrument height effects on 'EF-all(V/m)' measurements between installation and 2005.
• Applying the 'fair-weather' selection criteria from the cited publication to filter the 'EF-fair(V/m)' data for specific analyses.
• Studying interannual variability by comparing electric field values across different 'Year' and 'DoY' entries.

Strengths

• Data covers a 7-year period from 1998 to 2004.
• Includes both 1-minute averaged data (1998-2004) and 10-second data (2005-2006).
• Regular monthly calibration of the electric field mill is documented and applied.

Limitations

• Absolute electric field values are not determinable due to unknown instrument compression.
• Instrument height changed over time, complicating the interpretation of long-term trends.
• Data collection was intermittent over the 1998-2004 interval.
