Since May 11th, 2016 the GFS model is truely 4D and delivers hourly guidance. I've connected the charts module of the weather simulation with this high resolution source of weather data to display these variables: 2m temperature, surface wind speed incl. gusts, precipitation, long and short wave downward radiation flux.
Here is an interesting example of strongly raising temperatures in the next days close to Ambarchik, Siberia.
Fetching the data from the hourly model takes a little bit longer, up to ten seconds in some cases - thanks for your patience.
It was about time to spend this site a face lifting. Mobile Internet access became mainstream, the planet warmed by some more centigrades and many blogs and even portals (in Danish, German, Spanish, Polish, English) appeared reporting the state of the Arctic's cryosphere. So, a few experiments have been dropped and a weather simulation has been added.
All high level information and data is now concentrated on this start page. The explorer has changed a little and many visitors will appreciate that the circumpolar map + bathymetry are back. In future there will be little blogging - tweeting is much more fun. However, comprehensive articles are in the pipeline, e.g. why the pre-industrial baseline starts here way before 1850.
The plan was to update all past blogs before launch, but the Arctic set new priorities in recent weeks. The weather simulation is too useful to wait for any longer. So, old blogs will re-appear as time allows. During the migration is the atom feed disabled.
This weather simulation uses a particle system to render forecast and analysis data provided by NOAA/NWS/EMC's Global Forecast System (GFS). Currently active variables are: 10m wind speed, 2m temperatures and sea ice concentration.
Various pre-processed time ranges are available, the simulation loads about 100k weather and 50k sea ice data per day. AMSR2 sea ice concentration data starts with 2016-01-01 and is provided by University Hamburg, Germany.
A click on the map retrieves the latest five days forecast with a hourly resolution for chosen latitude/longitude pair.
You may want to share the animated or single frame GIF. It takes a few seconds to render the animated GIF, please stay patient. It consumes a lot of CPU power and works best with Chrome on desktop.
Hi, thanks for your interest. I really appreciate your feedback. The easiest way to reach me is the contact form. Usually I come back to you within 24 hours, assuming a working email address was provided.
