how to produce demo.nc? about 3d-wind-field

[RaymanNg]

Actually the data is from NOAA GFS, I just converted it from GRIB2 to NetCDF 3 format, and then used NetCDF operators to extract and process the data I need.

I don't think you should need the tempInvDim.nc or uv.nc if you want to use custom NetCDF data. Just make your own and ensure it contains the necessary values in the required format (read the updated README file for more info)

hello,can you tell me where are the NetCDF data from and how can i get it? thank you!

[RaymanNg]

The demo data is downloaded from NOAA Global Forecast System.
The original data is in GRIB2 format and I used toolsUI to convert the GRIB2 file to a NetCDF V3 file

hello, the demo only shows the wind direction，how does the demo to show the wind power？thank you!

[1287642889]

could you tell me how to download and show other climate data? for example ocean data、temperature data、humidity data and so on，thank you!

[RaymanNg]

Wind power is displayed by color

The scalar field (one value at one position, for example, temperature and humidity) can be displayed by WMS layer, you can read the source code in wind3D.js and the document of Cesium for how to use WMS layer

Excuse me， I use new netcdfjs(file) This file is provided by you named demo.nc but I got an ERROR that is 'Not a valid NetCDF v3.x file: should start with CDF' and I print the buffer.readByt(3) return "<!D"

can you tell me how to resolve this problem Thanks

[RaymanNg]

Do you mean you use a different version netcdfjs library? If so, please make sure you are using the latest version.

If you did not change the netcdfjs library, please check your netcdf file version, the README file states clearly that you should use netcdf v3 file

Thanks can you tell me that whitch Version about Cessium you used. now I Got An Error:[Cesium WebGL] Fragment shader compile log: ERROR: 0:? : '' : syntax error and my cessum version is 1.59.0

@xqwIOS
Sorry, I am busy these days...

For your problem, I think you should check your GLSL files location, because "ERROR: 0:? : '' indicates you are probably reading an non-exist file

[xqwIOS]

OK ， Thanks
