Contour detection

I just finished big improvements in the contour detection of the GRIBs. The performances are now correct (a few milliseconds per GRIB layer, for a full Pacific GRIB 2 degrees by 2 degrees).
Now the contour detection can be part of a GRIB Animation.
In addition, there are now new check boxes to show and hide already computed contour lines, just like for the faxes.
The picture shows PRMSL and 500HGT contours detected in a South Pacific GRIB. Notice that there is now an option to show only the detected contours (with no wind or other GRIB data).

Kick-ass Processing

That has been on my todo list for quite a while, rendering a GRIB with the Processing framework. Here is a first glance at what it can look like

Move the mouse on the figure to move the light. Drag the mouse to rotate the figure.
It is a 3D representation of the Pressure at Mean Sea Level on 2010-Feb-11.
I finally understood how the thread model of Processing is done. Once you get it, it's all downhill!

Archives 2009 available

From this page, you can now reach several kinds of archives, along with real-time data. We had in the past the composites archives - which can be opened and rendered by the Weather Wizard - we now have images generated after the composites, they can be visualized from your browser.
Check out this link for details.
