Characteristics and conditions of production of TLEs observed over a maritime storm

The coordinated European campaign of TLE observation in 2007 involved several cameras in southern France and northern Spain and lasted several months of summer, fall, and winter. Thanks to good conditions of observation at the camera locations and to several periods of long-duration storm activity, a large proportion of the TLEs (~90%) were observed from October to January over the Mediterranean Sea. Different types of TLEs (sprites, halos, elves) were produced by these maritime storms.
