Improve unstructured netCDF reader (FVCOM, Telemac, ...)

23

The [unstructured netCDF reader](https://github.com/OpenDrift/opendrift/blob/master/opendrift/readers/reader_netCDF_CF_unstructured.py) is far less developed than the counterpart for regular grids ([reader_netCDF_CF_generic](https://github.com/OpenDrift/opendrift/blob/master/opendrift/readers/reader_netCDF_CF_generic.py)). Things to improve: - the present version has no vertical interpolation, and returns [only surface...

When using plot() method with background field and vectors, the vectors are located at edge of grid cell. Should be at centre.

E.g. shall ```species``` in [Radionuclides](https://github.com/OpenDrift/opendrift/blob/master/opendrift/models/radionuclides.py#L39) model be an integer to be used for indexing, but is converted to float.

Timeout of Dataset constructor

7

For our operational service it would be useful with possibility to specify a timeout on calling netcdf4.Dataset on remote datasets (Thredds/OPeNDAP), e.g.: ``` f = Dataset(OPeNDAP_URL, 'r', timeout=10) ```

Core dump when opening OPeNDAP dataset after first creating local file

I encounter the following problem on Ubuntu 18.04 with conda and python 3.6-3.8 (not with Python2). libnetcdf version is 4.7.1, and is locked since I need gdal simultaneously. The following...

Apply scale and offset before checking valid_min/valid_max

Data is in the latest versions masked when outside . But apparently this does not work for variables where scale and offset is given, since the valid-checks seem to be...

Uniform random numbers for horizontal diffusion?

21

As noted by @Boorhin in the Slack channel, uniform random numbers are used for the vertical diffusion, whereas normal (gaussian) distributed random numbers are used for the horizontal diffusion: https://github.com/OpenDrift/opendrift/blob/master/opendrift/models/basemodel.py#L2416...
