SAIL - Fair weather atmospheric electric field data

Dataset of selected atmospheric electric field observations derived from the dataset of primary corrected electric field observations by applying the following criteria:

- Non-negative Potential Gradient values;

- Observations flagged as fully-ocean day;

- Dry day, according to manual precipitation records;

- Clear sky (meteorological optical range >= 30,000 meters);

Datafiles structure:

column 1: date/time (yyyy-mm-dd HH:MM:SS)

column 2: potential gradient 1-minute average (V/m)

column 3: longitude (degrees E)

column 4: latitude (degrees N)

Missing values are denoted by NA.
