ECMWF has just made available two month of data as teaser for their new coming reanalysis project, ERA5. ERA5 will finally give sense to the ERA-Interim...

How is Vortex turbulence computed?

We derive turbulence directly from our core model, WRF. This is a mesoscale model, or better a numerical weather prediction model, with multi-scale...

Does Vortex produce reliable results within a forest?

Vortex MAST results have been compared fairly successfully against user measurements taken inside or near a forest after certain precautions have been...

I have altitude or roughness data at a finer resolution than 100m. May I use them?

No, sorry. One of Vortex’s main aims is to provide our customers with fast results. This is only possible by automating the calculation process. Accepting...

At which height are Vortex SERIES computed?

Vortex SERIES are delivered at any height between 50 and 150m a.g.l. However, be aware than SERIES are a Mesoscale product of 3km-resolution, thus not...

How far is your time series nearest calculation node away from my mast?

Since SERIES (like all Vortex products) are computed on demand, their calculation domain is centered on your selected point of interest so “distance to...

I want to MCP my short-term data. Does Vortex offer time series?

Yes, Vortex SERIES provide Mesoscale reference time series: 10 years of hourly data at any location world wide.

How accurate is Vortex?

Current Vortex system accuracy values are presented here. These values change periodically thanks to the feedback of our users, who compare Vortex...
