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 &gt;= 30,000 meters);<br>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.
