Solution Overview
Problem
Current systems for collecting meteorological data in the ocean-atmospheric boundary layer face challenges such as limited spatial and temporal resolution, high costs, and unreliable data transmission, particularly in deploying autonomous sensor platforms like unmanned surface vehicles (USVs) that require stable and flexible data collection and processing capabilities.
Innovation Solution
The Distributed Autonomous Meteorological Stations (DAMES) system employs a network of sensor-bearing USVs with advanced wireless communication and collaborative data processing, enabling scalable, adaptable, and resource-efficient data collection and transmission, integrating sensing, communication, and control capabilities to achieve high spatial and temporal resolution.

Engineering Contradiction Analysis
1Measurement precision
If autonomous sensor platforms (USVs) are deployed for meteorological data collection, then spatial and temporal resolution of measurements is improved, but system cost and complexity increase
Solution Approach 1:
The system divides the monitoring task into multiple independent USV nodes, each equipped with sensors and processing capabilities. Each node autonomously collects and processes local meteorological data, then transmits results to the network. This segmentation allows high-resolution spatial coverage through multiple units while keeping individual node complexity manageable.
Solution Approach 2:
Each USV node is designed as a multi-functional platform that performs sensing (meteorological measurements), communication (data transmission), and control (autonomous navigation and station-keeping). This universal design consolidates multiple functions into single units, improving measurement capabilities without proportionally increasing overall system complexity.
2Adaptability or versatility
If autonomous sensor platforms are deployed, then data collection flexibility is improved, but reliability of data transmission deteriorates under challenging sea conditions
Solution Approach 1:
The USV platforms employ dynamic position-keeping capabilities that automatically adjust to changing sea conditions, maintaining stable sensor positions despite wave motion. The systems adapt their operational parameters in real-time based on environmental conditions, ensuring continuous reliable data collection and transmission even in challenging marine environments.
3Extent of automation
If satellite-communication-based gliders are used, then autonomous data collection capability is achieved, but cost increases prohibitively
Solution Approach 1:
The system employs multiple low-cost USV nodes that can be deployed in large numbers rather than relying on expensive satellite-based gliders. Each node is designed to be economically viable for mass deployment, with simplified communication requirements that reduce dependence on costly satellite infrastructure while maintaining autonomous operational capabilities.
