I didn't realize how hot eastern china was!

Most of China's 3million+ cities are on the east coast, the west is relative unpopulated. I was there in November and while the results of this map shouldn't have surprised me, considering the extreme city expansions I saw, I was still very surprised to see that half the country is at the same level as Saudi Arabia!

This isn't a map. This is a simulation. You made a simulation, and are outputting the results. This teaches you nothing whatsoever except that your model has pretty colors. Next thing someone is going to take these results, use them as input data for a new model, then send the results of that new model back as data for the first.

This isn't a map. What would a better map be? Is your point that they are doing interpolation on something that is already interpolated? Or are you implying that there is no way to create a map of temperature using only point measurements? I would like to know how well this data matches the raw station measurements (and verification measurements) but I think it's a decent visualization of likely real time temperature…

Yes.

Maybe I'm being pedantic, but to me this is a 2D visualization of a simulation. But it is not a map.

It's a cool project, but... >>It regenerates every hour, providing a constantly updating snapshot of air temperature around the globe. Once per hour is not "real-time." It's "once per hour."

There are plenty of existing "hourly" climate data products (http://www.erh.noaa.gov/pbz/hourlyclimate.htm and http://rda.ucar.edu/datasets/ds093.1/ are two examples.) Calling this one "real-time" is needlessly confusing, because "real-time" sounds like it should somehow be better than "hourly," but it's not.

As a cartographer, this absolutely is a map. A map showing a simulation. "Map" just means there is a spatial component to the visualization.

Celsius please. But besides that: Very nice, very clear and way better than supid sun and cloud icons with temperatures next to them over some vague areas.

Absolutely. Only about 320 million [1] out of 7 billion people still use fahrenheit. [1] http://en.wikipedia.org/wiki/Fahrenheit#Usage

It's less than the percentage of the world still using IE6!

Even if normalized for people that actually have Internet access? Honest question.

Real time means that a calculation ends before the next update. Real time doesn't say anything about rate but means there is a constant rate.

The IE6 share is going to be higher when normalized for people with Internet access, so the comparison is going to hold by a wider margin.
