Improved Sea Ice videos

UPDATE: High speed video from 2004 to present added below.
In response to recent discussions, I’ve taken the time to download the 2.8 gb of data required to plot sea ice. I found a far better software for video creation called virtual dub. And I rescaled the graphs so that the Arctic and Antarctic are plotted on equal grid scales. The pixel resolution is 25km and the satellite ice data comes from the NSIDC Sea Ice Concentrations as collected from the Nimbus-7 SMMR and DMSP SSM/I Passive Microwave systems. This version represents just a few years of the total dataset and is similar to my previous publicaitons. You may note the higher resolution and frame rate than my previous work. Currently, I’m compiling the complete video for publication tomorrow. The purpose of the project is to first visually see if 2009 – 2011 which is not shown here, has similar weather patterns to 2007. Also, I hope to add sea surface temperature and flow directions to the video – both of which will probably add to our understanding of the sea ice situation. If I’m lucky, there may be some stats to follow as well.
