Copernicus data integration via WMS service problem


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 :

See services for WMS access, here is the capabilities :

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 : ‘’,
    layers : ‘temperature’,
    parameters : {
        version : ‘1.3.0’,
        format : ‘image/png’,
        CRS : ‘EPSG:4326’

So here is what would look like one request :

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 ?



CORS hits me again !

Problem solved
