We show how component-level understanding – obtained when scientists can link model behavior to parts within the overall model – should guide the development and evaluation of ML models. Better understanding yields a stronger basis for trust in the models. We highlight several examples to demonstrate.</p> <p class="more-link my-1 text-right "><a class="external"href="https://gmd.copernicus.org/articles/18/787/2025/gmd-18-787-2025.html" aria-label="Read more about Moving beyond post hoc explainable artificial intelligence: a perspective paper on lessons learned from dynamical climate modeling">Read more</a> </div> </article> <hr> <article class="media"> <img role="presentation" alt="" class="img-fluid img-thumbnail" src="https://www.egu.eu/media/news/highlightarticles/2025/02/10/f20a4b89-edbd-4b6e-84e0-aab867ec9228.png.120x120_q90_crop_upscale.png" srcset="https://www.egu.eu/media/news/highlightarticles/2025/02/10/f20a4b89-edbd-4b6e-84e0-aab867ec9228.png.120x120_q90_crop_upscale.png 1x, https://www.egu.eu/media/news/highlightarticles/2025/02/10/f20a4b89-edbd-4b6e-84e0-aab867ec9228.png.240x240_q90_crop_upscale.png 2x" loading="lazy"> <div class="media-body"> <a class="h4 external" href="https://nhess.copernicus.org/articles/25/581/2025/nhess-25-581-2025.html">Causes of the exceptionally high number of fatalities in the Ahr valley, Germany, during the 2021 flood</a> <ul class="list-inline mt-1"> <li class="list-inline-item"><i class="far fa-fw fa-newspaper"></i> <a class="external" href="https://www.natural-hazards-and-earth-system-sciences.net/">Natural Hazards and Earth System Sciences</a></li> <li class="list-inline-item"><abbr class="initialism" title="Digital object identifier">DOI</abbr> <a class="external" href="https://doi.org/10.5194/nhess-25-581-2025">10.5194/nhess-25-581-2025</a></li> <li class="list-inline-item"><i class="far fa-fw fa-calendar-plus"></i> 12 February 2025</li> </ul> <p>In July 2021, flooding killed 190 people in Germany, 134 of them in the Ahr valley, making it the deadliest flood in recent German history.

It is based on 2 km horizontally gridded observations along the swaths of SWOT (Surface Water and Ocean Topography) track 20 during the calibration/validation phase (Cal/Val, 1 d orbit) from late March to early July 2023. We evaluate the amplitude of M2, N2, and S2 frequencies and use the M2 atlas as an internal tide correction model for SWOT observations. Internal tide amplitudes (models or atlases) are first derived by harmonic analysis of the SWOT sea level anomaly (SLA). The estimation is improved by performing a principal component analysis before the harmonic analysis. The results compare very well with the high-resolution empirical tide (HRET) internal tide model, the reference product for internal tide corrections in altimetry observations. The coherent mode 1 and mode 2 M2 can be distinguished in the internal tide model derived from SWOT, while the higher modes with their strong SLA signature are seen mostly in the incoherent part. In comparison to HRET, the correction of SWOT observations with SWOT-based atlases may be more relevant for this track.</p> <p class="more-link my-1 text-right "><a class="external"href="https://dx.doi.org/10.5194/os-21-325-2025" aria-label="Read more about Internal tides off the Amazon shelf in the western tropical Atlantic: analysis of SWOT Cal/Val mission data">Read more</a> </div> </article> <hr> <article class="media"> <img role="presentation" alt="" class="img-fluid img-thumbnail" src="https://www.egu.eu/media/news/highlightarticles/2025/01/27/e14d1be2-1961-4c92-bed5-0a3246e15b42.png.120x120_q90_crop_upscale.png" srcset="https://www.egu.eu/media/news/highlightarticles/2025/01/27/e14d1be2-1961-4c92-bed5-0a3246e15b42.png.120x120_q90_crop_upscale.png 1x, https://www.egu.eu/media/news/highlightarticles/2025/01/27/e14d1be2-1961-4c92-bed5-0a3246e15b42.png.240x240_q90_crop_upscale.png 2x" loading="lazy"> <div class="media-body"> <a class="h4 external" href="https://dx.doi.org/10.5194/os-21-181-2025">The alongshore tilt of mean dynamic topography and its implications for model validation and ocean monitoring</a> <ul class="list-inline mt-1"> <li class="list-inline-item"><i class="far fa-fw fa-newspaper"></i> <a class="external" href="https://www.ocean-science.net/">Ocean Science</a></li> <li class="list-inline-item"><abbr class="initialism" title="Digital object identifier">DOI</abbr> <a class="external" href="https://doi.org/10.5194/os-21-181-2025">10.5194/os-21-181-2025</a></li> <li class="list-inline-item"><i class="far fa-fw fa-calendar-plus"></i> 31 January 2025</li> </ul> <p>Mean dynamic topography (MDT) describes variations in the mean sea surface height above a reference surface called a geoid.
