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.

This is pretty impressive, i wonder what the update interval and source is.

http://www.mapbox.com/labs/forecast/temperature/ I really like the interface, even the zoom buttons could be removed or hidden as you can scrool-zoom.

Make the temperature in Celsius please!

EDIT: There seem to be a problem with the algorithms, the largest zoom displays colder temperatures( look at the temperature map ).

Largest zoom,

I am proud of forecast.io for sticking with a 'normal' color palette here, rather than the non-standard purples they have chosen for radar; as a meteorologist the purple radar hurts my brain, but this map is completely cool.

Also there are definitely some quality control issues with the RTMA data, so you can bump into the garbage-in-garbage-out issue with it, but overall, this is a very nice start to something that could ultimately be quite useful.

I was also impressed but concur that there seems to be significant loss when zoomed out. I'm not sure how they sample for the larger scales, but it seems very inaccurate.

Hmm, there are some superlatives ("highest resolution") in here I'm not sure about. Lots of groups create maps like this for modeling purposes. One for sea surface temperature is:

http://ourocean.jpl.nasa.gov/SST/

This is a blended product (i.e., multi-instrument, and gaps filled) with 1km resolution. There is also a 1km MODIS land surface temperature data product:

http://modis.gsfc.nasa.gov/data/dataprod/dataproducts.php?MO...

Neither of these is real-time (more like daily).

The color palette adjusts based on the zoom level in order to improve contrast. Roughly a bazillion people pointed out that it's "broken", so I guess that was a dumb call on my part!

Thank MapBox. If it were up to me, I'd do something funky like a blackbody-esque color palette and then get yelled at because it'd be hard to read. :-)

"Real-time" is the key. As far as we know, there isn't another real-time global data product that is this high resolution.

And while we actually use MODIS data as an input to our temperature correction model, it is, as you mentioned, land surface temperature, whereas our map represents near-surface air temperature (i.e., what you'd get in a normal weather report).
