Data Quality Assessment, Representativeness, and External Consistency of a Coastal Oceanographic Buoy Using Copernicus Marine and ERA5 Products.
Article in Sensors (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Coastal oceanographic buoys provide high-frequency observations, but their scientific use requires channel-specific quality assessment and explicit treatment of representativeness. This study evaluates a coastal buoy deployed off Cabo de Gata, southeastern Spain, during two non-contiguous observation windows in 2025 and 2026. Buoy records were standardized, screened with quality-control tests, aggregated daily without gap filling, and compared with Copernicus Marine and ERA5 products as an external-consistency assessment. Gridded products were interpolated to the mean buoy position using inverse-distance weighting, and Copernicus Marine temperature was vertically interpolated to the 5 m and 10 m buoy-sensor depths. Completeness was 88.1-88.3% in 2025 and 99.9-100.0% in 2026, with no gross-range failures. Significant wave height and atmospheric pressure showed strong external consistency, with root mean square errors of 0.15/0.14 m and 0.63/0.59 hPa, respectively. Temperature at 5 m showed moderate-to-strong agreement, with errors of 0.98/0.64 °C. Wave-spectrum-derived wind speed showed larger, sea-state-dependent differences, although disagreement decreased under higher wave steepness. The workflow distinguishes channels suitable for daily environmental interpretation from those requiring additional metadata or independent field verification.
