Hi, I'm trying to integrate some Copernicus open data in Cesium but my attempt failed so far. This is the data I want to use : [http://marine.copernicus.eu/web/69-myocean-interactive-catalogue.php?option=com\_csw&view=details&product\_id=GLOBAL\_ANALYSIS\_FORECAST\_PHYS\_001\_002](http://marine.copernicus.eu/web/69-myocean-interactive-catalogue.php?option=com_csw&view=details&product_id=GLOBAL_ANALYSIS_FORECAST_PHYS_001_002) See services for WMS access, here is the capabilities : [http://atoll.mercator-ocean.fr/opendap-mercator-myocean/thredds/wms/global-analysis-forecast-phys-001-002?version=1.3.0&request=GetCapabilities&service=WMS](http://atoll.mercator-ocean.fr/opendap-mercator-myocean/thredds/wms/global-analysis-forecast-phys-001-002?version=1.3.0&request=GetCapabilities&service=WMS) I'm not very accointed with WMS service, so I might do thing the wrong way, but here what looks like my code : var viewer = new Cesium.Viewer('cesiumContainer'); // Add a WMS imagery layer var imageryLayers = viewer.imageryLayers; imageryLayers.addImageryProvider(new Cesium.WebMapServiceImageryProvider({     url : ‘[http://atoll.mercator-ocean.fr/opendap-mercator-myocean/thredds/wms/global-analysis-forecast-phys-001-002](http://atoll.mercator-ocean.fr/opendap-mercator-myocean/thredds/wms/global-analysis-forecast-phys-001-002)’,     layers : ‘temperature’,     parameters : {         version : ‘1.3.0’,         format : ‘image/png’,         CRS : ‘EPSG:4326’     } })); So here is what would look like one request : [http://atoll.mercator-ocean.fr/opendap-mercator-myocean/thredds/wms/global-analysis-forecast-phys-001-002?version=1.3.0&format=image%2Fpng&crs=EPSG%3A4326&service=WMS&request=GetMap&styles=&layers=temperature&srs=EPSG%3A4326&bbox=0%2C0%2C90%2C90&width=256&height=256](http://atoll.mercator-ocean.fr/opendap-mercator-myocean/thredds/wms/global-analysis-forecast-phys-001-002?version=1.3.0&format=image%2Fpng&crs=EPSG%3A4326&service=WMS&request=GetMap&styles=&layers=temperature&srs=EPSG%3A4326&bbox=0%2C0%2C90%2C90&width=256&height=256) If you try it, you'll see the image corectly in your browser. But Cesium does not want to load it. The network developer tab of firefox indicate a '200 OK' response from these requests, but when I hover my mouse over it I have something that say "impossible to load the image", and no thumbnails. Any hint why this is not working properly ? Thanks Olivier ---

How did you solve it? Did you have to use a browser extension? ---
