Abstract: Raincloud formation depends on the creation of Cloud Condensation Nuclei (CCN) around which water molecules cluster, generating a nano-particles (nano-cluster), then a micro-cluster and finally a water droplet. A collection of such water droplets constitutes a cloud which may spontaneously produce precipitation (in the form of rain, hail or snow) or precipitation induced by cloud seeding. The CCN is the result of nucleation processes. In this patent application, a process is described wherein said nucleation is catalyzed by the injection of a chemical substance, dimethylamine, into the upper atmosphere, preferably through injection of said substance into an electron rich aircraft engine exhaust. The subsequent formation of negatively charged ions has a catalytic effect on the generation of said CCNs.

Abstract: An underground storage system for drip irrigation products is described herein. Drip irrigation systems may include an outlet connected to a tube filled with continuously flowing water, in which the water pressure must be high enough to force droplets out of the outlet and onto the soil. This is controlled by an irrigation control valve. The droplets then deposit on the surface of the soil surrounding the plant.

Abstract: This disclosure relates generally to root zone moisture estimation for vegetation cover using remote sensing. Conventionally, it is challenging to estimate root zone soil moisture using only satellite data.
