To catch the AURA overpass at 6:50am, July 16th 2007(UTC), ELF is run at midnight. It is cloudy during the run. But it is still a very interesting night. There is an aloft layer at around 1km, which is from the west of UMBC from HYSPLIT. The hourly PM 2.5 concentrations in the range of 11.6 to 18 ug/m3 were recorded at Maryland's Department of the Environment Oldtown site in Baltimore during ELF's operation.
