Query: Detection of terrestrial gamma-ray flashes with the AGILE/MCAL   AGILE is one of the satellites currently detecting terrestrial gamma-ray
flashes (TGFs). In particular, the AGILE Mini-CALorimeter detected more than
2000 events in 8 years activity, by exploiting a unique sub-millisecond
timescale trigger logic and high-energy range. A change in the onboard
configuration enhanced the trigger capabilities for the detection of these
events, overcoming dead time issues and enlarging the detection rate of these
events up to $>$50 TGFs/month, allowing to reveal shorter duration flashes. The
quasi-equatorial low-inclination ( 2.5$^{\circ}$) orbit of AGILE allows for the
detection of repeated TGFs coming from the same storms, at the same orbital
passage and throughout successive orbital overpasses, over the same geographic
region. All TGFs detected by AGILE are fulfilling a database that can be used
for offline analysis and forthcoming studies. The limited number of missions
currently detecting these brief terrestrial flashes makes the understanding of
this phenomenon very challenging and, in this perspective, the AGILE satellite
played and still plays a major role, helping shedding light to many aspects of
TGF science
