Thanks! I'm a sysadmin at met.no, and will forward your comments to the devs.

I found the OP solution interesting in regards to visualizing historical observations. As of now, we have a system seperate from yr.no for that (but I believe it is still accessible from api.met.no).

Great work on the graphics - concise and informative.

Coverage in western Europe for wind speed and pressure on the advanced map is limited to the North Sea, and Northeastern Atlantic. Is this due to limited access to the data or because Scandanavians think that it is always sunny and warm in Iberia so the weather is not worth reporting.

Our primary sector is the Northern Atlantic and the North Sea from Faroe Islands/Iceland and up to and including the Arctic. We do those calculations based on observations from several sources (like weather stations, weather balloons and satellite imagery) that we feed into our meteorological and oceanographic models. The stuff we create for our sector are in principle always made public, and you'll see those products on yr.no and on the API.

We also retrieve and use observations and products from partner institutions like NOAA (US) and the ECMWF (EU). Some of the partners (mostly national services) do not accept redistribution, so some areas might unfortunately only have basic meteorological and oceanographic data made available on our API.

It's amazing how popular yr.no has become. We got word from some South African farmers who said they were using yr.no instead of their national service, as our service was of better use for them. (The distance between Oslo and Johannesburg is 6010 miles.)
