Description

FIELD OF THE INVENTION

The present invention relates generally to the field of geoengineering, and more particularly to monitoring, using smartphones, the effect achieved by spraying of sun-reflecting particles into the stratosphere, to address global warming.

BACKGROUND OF THE INVENTION

The idea of cooling down the planet by spraying sun-reflecting particles into the stratosphere is known in the art. These particles serve as radiation filters which block some of the sunlight and effectively reduce the average temperature of the atmosphere.

Implementing this idea is very challenging and far from trivial. Apart from the complicated logistics involved in orchestrating a huge fleet of airplanes that can spray these particles, it is desirable to monitor the effect of the process of the sprayed particles on the temperature in many locations simultaneously to avoid over-cooling.

There is a need therefore for monitoring the temperature and other atmospheric parameters in millions of geographical locations and deducing trends of temperature change.

SUMMARY OF THE INVENTION

Some embodiments of the present invention provide a method and a system for monitoring the spraying of sunlight reflecting particles into the stratosphere to address global warming using smartphones. The method may include the following steps: spraying, using a plurality of airplanes flying through a plurality of different geographical locations, sunlight reflecting particles, in accordance with a spraying scheme; sampling using sensors of a plurality of smartphones located in a plurality of different geographical locations, a plurality of atmospheric measurements; training, using a computer processor, and based on the plurality of atmospheric measurements, a model configured to predict a trend in a change of temperature in consequence of the spraying of the sunlight reflecting particles; and repeatedly updating the spraying scheme based on the model.

The system may implement the method using a plurality of smartphones connected to a computer processor over a cloud, using a dedicated application that controls the various sensors which are built in the smartphones or are implemented using a dedicated software thereon.

In one embodiment, server 145 and mobile communications device 115 directly or indirectly accesses a bus 200 (or other communication mechanism) that interconnects subsystems and components for transferring information within server 145 and/or mobile communications device 115. For example, bus 200 may interconnect a processing device 202, a memory interface 204, a network interface 206, a peripherals interface 208 connected to I/O system 210, and power source 209.

For example, the processing device may include one or more integrated circuits, microchips, microcontrollers, microprocessors, all or part of a central processing unit (CPU), graphics processing unit (GPU), digital signal processor (DSP), field programmable gate array (FPGA), or other circuits suitable for executing instructions or performing logic operations. The processing device may include at least one processor configured to perform functions of the disclosed methods such as a microprocessor manufactured by Intel™. The processing device may include a single core or multiple core processors executing parallel processes simultaneously. In one example, the processing device may be a single core processor configured with virtual processing technologies. The processing device may implement virtual machine technologies or other technologies to provide the ability to execute, control, run, manipulate, store, etc., multiple software processes, applications, programs, etc. In another example, the processing device may include a multiple-core processor arrangement (e.g., dual, quad core, etc.) configured to provide parallel processing functionalities to allow a device associated with the processing device to execute multiple processes simultaneously. It is appreciated that other types of processor arrangements could be implemented to provide the capabilities disclosed herein.

In some embodiments, processing device 202 may use memory interface 204 to access data and a software product stored on a memory device or a non-transitory computer-readable medium. For example, server 145 may use memory interface 204 to access data structure 146. As used herein, a non-transitory computer-readable storage medium refers to any type of physical memory on which information or data readable by at least one processor can be stored. Examples include random access memory (RAM), read-only memory (ROM), volatile memory, nonvolatile memory, hard drives, CD ROMs, DVDs, flash drives, disks, any other optical data storage medium, any physical medium with patterns of holes, a RAM, a PROM, and EPROM, a FLASH-EPROM or any other flash memory, NVRAM, a cache, a register, any other memory chip or cartridge, and networked versions of the same. The terms “memory” and “computer-readable storage medium” may refer to multiple structures, such as a plurality of memories or computer-readable storage mediums located within mobile communications device 115, server 145, or at a remote location. Additionally, one or more computer-readable storage mediums can be utilized in implementing a computer-implemented method. The term “computer-readable storage medium” should be understood to include tangible items and exclude carrier waves and transient signals.

Both mobile communications device 115 and server 145 may include network interface 206 coupled to bus 200. Network interface 206 may provide two-way data communications to a network, such as network 150.

In one embodiment, network interface 206 may include an integrated services digital network (ISDN) card, cellular modem, satellite modem, or a modem to provide a data communication connection over the Internet. As another example, network interface 206 may include a wireless local area network (WLAN) card. In another embodiment, network interface 206 may include an Ethernet port connected to radio frequency receivers and transmitters and/or optical (e.g., infrared) receivers and transmitters. The specific design and implementation of network interface 206 may depend on the communications network(s) over which mobile communications device 115 and server 145 are intended to operate. For example, in some embodiments, mobile communications device 115 may include network interface 206 designed to operate over a GSM network, a GPRS network, 3G, LTE, 5G, an EDGE network, a Wi-Fi network, and a Bluetooth® network. In any such implementation, network interface 206 may be configured to send and receive electrical, electromagnetic, or optical signals that carry digital data streams representing various types of information.

Touch screen 218 may also, for example, be used to implement virtual or soft buttons and/or a keyboard. While touch screen 218 is shown in FIG. 2, I/O system 210 may include a display screen (e.g., CRT or LCD) in place of touch screen 218. Audio controller 214 may be coupled to a microphone 220 and a speaker 222 to facilitate voice-enabled functions, such as voice recognition, voice replication, digital recording, and telephony functions. The other input controller(s) 216 may be coupled to other input/control devices 224, such as one or more buttons, rocker switches, thumbwheel, infrared port, USB port, and/or a pointer device such as a stylus.
