OTT Rain Gauges Used in Remote Precipitation Monitoring Stations in Andes Mountains

There are remote monitoring locations, and REMOTE monitoring locations!

Appalachian State University, in partnership with a multitude of other universities and the National Science Foundation, has undertaken the task of installing weather monitoring stations very high up in the Andes Mountains, on the Quelccaya Icecap (18,537 ft (5,650 m) ) in Peru and at Chacaltaya (16,929 ft (5,160 m) ) in Bolivia. Both stations included the OTT Pluvio2 Weighing Precipitation Gauge and the OTT Parsivel2 Weather Laser Disdrometer.

An Introduction to Communication Modules for Water Resource Professionals

In systems that deliver water resource data to hydromet professionals, equipment within the system must communicate with each other. Systems consist of components like sensors, data loggers, control systems, and telemetry units. For data to be available, information such as measurement results, diagnostic data, and instructions for how and when to operate must be transferred between system components. Communication between the components within the system requires compatible connections and adherence to strict rules. Otherwise critical information may be lost or data communication may stop completely.

To allow communication efficiency and accuracy, rules are established so that elements of the system will link effectively. These rules of communication are referred to as communications protocols. Protocols exist for communicating through wired connections and telemetry. They may describe requirements for the system’s hardware, software, or both. Normally the rules establish things like common sets of commands, structure of messages, where and when to send information, how to acknowledge and verify communication, speed of transmission, one-way or two-way communication, connection standards, hardware specifications, power requirements, or more. Depending on the communications protocol, there may be more or fewer elements of the rules.
