A communication system uses skywave propagation to transmit data between communication nodes over a data transmission path. An atmospheric sensor is configured to collect atmospheric data at the reflection point of the data transmission path where the transmission path is redirected from the atmosphere toward the surface of the Earth. Data collected by the atmospheric sensor may be used to predict future ionospheric conditions and determine optimum working frequencies for transmission of data between the communication nodes.

Systems and methods may be configured for providing preemptive reenergizing alerts designed to alert vehicle users to reenergize their vehicles in anticipation of power disruption conditions. Weather related data and/or grid related data may be leveraged for predicting the likelihood of power disruption conditions of a grid power source. When power disruption conditions are likely to increase the cost of energy by greater than a predefined threshold, one or more reenergizing alerts may be automatically communicated for alerting the users of the need to reenergize (e.g., refuel, recharge, etc.) their vehicles. Preemptively alerting users to reenergize their vehicles in this manner may ensure that the vehicle will be available for use as a backup power source during actual power disruption conditions.

Methods, apparatuses, systems and computer program products are disclosed to estimate road surface temperature for a geographic location. Reference ambient sensor data indicative of ambient conditions in vicinity to mobile vehicles are retrieved. Reference roadside sensor data indicative of at least road surface temperature in vicinity to distributed roadside sensors are retrieved. A relationship is established between the reference ambient sensor data and road surface temperature, based on the reference ambient sensor data and based on the reference roadside sensor data. A data structure is created, encoding the established relationship. Further, current vehicle ambient sensor data, indicative of current ambient conditions in vicinity to the one or more vehicles, are collected at one or more vehicles. Finally, a road surface temperature estimate is determined for the geographic location, using the data structure and using the collected current vehicle ambient sensor data.

Disclosed are a runoff estimating method and a runoff estimating device for an ungauged region. The method includes: acquiring driving data, the driving data comprising monthly-scale precipitation, monthly-scale potential evapotranspiration, and soil water volume content of a basin within a preset period; establishing an objective function of monthly-scale water quantity balance change of the basin, and determining a parameter to be calculated in the objective function; initializing the parameter to obtain an initial value of the parameter; inputting the initial value of the parameter and the driving data into the objective function to obtain an initial function value of the objective function; performing an iterative computation on the parameter based on the initial value of the parameter and the initial function value to obtain an optimized value of the parameter, and inputting the optimized value of the parameter into the objective function to obtain an objective function value.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for automating bulk location-based actions in response to disaster events. A system obtains data defining zones related to different geographic locations and configures a set of preferences for each zone. One of the preferences is a command for responding to an event. The system detects a disaster event and determines that a location affected by the event is related to a zone defined at the system. The system obtains sensor data generated by a sensor in the zone that is connected to a monitoring system for the zone. The system generates an alert based on the sensor data and the command and provides the alert to a client device of an entity that manages properties in the zone. The alert provides an assessment of how the disaster event affects items at properties in the zone.
