Short summary
We present the magnetic local time (MLT) distribution of energetic particle precipitation into the ionosphere in combination with different substorm activities. In the long term average substorms may increase the night-sector flux by factor 2–4 and eventually reduce the day-time flux. The MLT flux differences themselves may even reach 2 orders of magnitude independently of substorm activity level. Since precipitating particles impact the ozone chemistry, this may have atmospheric implications.
