“…Since initial field test and evaluation results were collected at the Duck, NC station and reported in references [1] and [2], CO-OPS has expanded its field demonstration efforts to include three additional sites, each with different coastal environment types. Results for all three new locations further demonstrate the radar sensors performance capabilities and potential to serve as an operational system.…”

“…Previously reported work focused on evaluating the wave measurement capability and efficacy of microwave radars in the CO-OPS' inventory [1], [2]. Several radar sensors advertise wave measuring capabilities, but few studies have presented wave heights measured directly from radar water level sensors.…”

“…For previously reported results summarized in references [1] and [2], wave parameters were computed manually, post data collection, using raw 1 Hz water level measurements from the radar tide gauge, downloaded remotely from the system's data logger. We computed hourly spectral densities from the 1 Hz water level time series using a Welch FFT approximation with Mathworks MATLAB software.…”

The NOAA Center for Operational Oceanographic Products and Services (CO-OPS) maintains the National Water Level Observation Network (NWLON), consisting of over 200 stations providing real-time water level observations along U.S. coasts. The transition to microwave radars as the primary water level sensors at most stations has allowed for the exploration of the sensor's wave measurement capability and plans to incorporate nearshore wave observations into the network. CO-OPS currently does not operate and maintain any wave measurement systems, but the new radar water level sensors offer a cost-effective way to enhance nearshore wave coverage for navigational safety and ocean research.Previously reported work evaluated the wave measurement capabilities of microwave radars in the CO-OPS inventory [1], [2]. Initial field tests showed that the Xylem WaterLOG H3611 radar, currently deployed at NWLON stations, had an output limited temporal resolution for accurately measuring highfrequency wind waves. However, the Endress+Hauser Micropilot M FMR240 (E+H) radar, which serves as the base sensor component for the WaterLOG, demonstrated better performance in resolving higher-frequency energies without low-frequency aliasing issues.Recent efforts that have followed previous reports involve demonstrating radar water level sensor wave measurement performance at a broader range of coastal environment types and implementing real-time, automated wave processing capability on the field systems data logger. We will provide a detailed description of the latest wave processing and transmission capabilities, along with latest data results from new field stations.
