Short summary
We document for the first time the diurnal cycle of the clouds in the tropical stratosphere, using the measurements from the lidar on board the International Space Station. The stratospheric clouds are concentrated over the convective centers. Their cloud fraction is minimal and limited to the vicinity of the tropopause during daytime. It presents two maxima: one in the early night and one shortly after midnight, when clouds also extend deeper in the stratosphere.
