The Army calls it Future Combat Systems (FCS), and the non-line-of-sight cannon is one essential part of that future. The Future Combat Systems will employ unmanned vehicles like airborne reconnaissance drones, unmanned heavy vehicles like the Crusher, and remotely fired missile arsenals. Manned...
However, geostationary satellites provide excellent spatial and temporal coverage of the often long﹍asting convective storms that deliver heavy rain, lightning and strong winds, presenting a valuable opportunity for satellite nowcasting. Here, we evaluate the skill of satellite nowcasting products for ...
