Sampling at rural background sites is often taken as representative for large areas. However, our measurement shows that vertical representativeness
might be very short when mixing height become low especially due to night time inversions. To assess the difference between nonrefractive PM1 (NR-PM1)
composition at two heights depending on current meteorological conditions a long sampling tube was used to sample from 230 m AGL of 250 m high ICOS
