General information

-------------------

The THREDDS Data Server (TDS) is a web server that provides metadata

and data access for scientific datasets, using OPeNDAP, OGC WMS and

WCS, HTTP, and other remote data access protocols.

thredds.met.no is an archive service operated by MET Norway for

publishing historical and current research data. All datasets can be

downloaded in NetCDF format or extracted using the OPeNDAP protocol.

Some datasets can also be visualized using the WMS protocol.

Examples of the datasets available include:

* Weather forecasts

* Climate Modelling

* Air Pollution forecasts

* Radioactivite fallout simulations

* Volcanic Ash drift models

* Observations

* Nordic Gridded Climate Dataset

* OSI SAF

* seNorge

* Remotesensing archive

* Lightning events

* Ocean and Ice observations and forecasts

* Satellite images

MET Norway Numerical Weather Prediction products

------------------------------------------------

These are the models operated by MET Norway for our forecasting

services (locationforecast, nowcast and so on). Note that the

long-term and global forecasts are produced by ECMWF and not available

for download due to licensing terms.

The NWP datasets can be found in the Weather forecasts folder on

thredds.met.no.

Documentation for the various models can be found on the Numerical

Weather Prediction wiki.

For a general overview of the different simulation models used in our

forecasts, please see the respective data model documentation page:

* Locationforecast

* Nowcast

* Oceanforecast
