Measurements of atmospheric space charge at 0.1, 1 and 2m above the ground surface, the potential gradient at the ground and the positive and negative conductivity at 12cm above the ground have been made at a frequency of 1 Hz at different times of the day. Short time variations in each of these parameters are studied. Night-time observations of space charge at the three levels show features typical of space charge movement in a stable stratified atmosphere, while daytime observations are typical of space charge movement in a well mixed turbulent atmosphere. Short time variations of a parameter generally seem to follow the magnitude of the parameter. The short time variations of the potential gradient and conductivity are in accordance with Ohm's law.
