Model validation

If you want to validate our models with your own sensor data please contact us at

Validation of the model is an ongoing effort and we seek collaboration with everyone that have access to instruments that can be used to validate or correct our simulations. If you are a potential customer and want to check how well our model corresponds to your own observations please be in touch and we will provide a comparison between observed data and simulations from our model in the same time-period like the one below.

Conclusion: The model is corresponding very well to observed data in the same location over time.

Example: This example is a comparison of measured current and modeled current at 10m depth in January to Febuary 2023 in Gimlingsundet (65°12.527 N, 11°58.524 Ø).

Image 1: Rose histograms showing the distribution of current velocities at 10m depth from measurements (left) and model (right).  Each bin shows the distribution in the direction indicated by the orientation of the bin (up: northward current, right: eastward, down: southward, left: westward). The length of each bin indicates the proportion of samples (%) occuring in the direction of the bin, and the colors show the speed distribution in the corresponding direction. E.g., the more of the color light green in a sector, the more of currents speeds between 24 cm/s and 28 cm/s in that direction.

 Image 2: Time series of speed at 10m depth from measurements (blue) and model (orange). 

Image 3 (left): Percentiles of measured speed vs. Percentiles of modeled speed (grey dots). Squares mark specific percentiles. In this case the 50th percentile (median) was 9 cm/s in the measured data and 10 cm/s in the modeled data.
