|| Sea Ice ||Much of the northern latitude cold bias is linked to excessive ice production. Encouraging the melting of the ice thus helps. Sea-ice albedo is tempertaure dependent, between a low "melting" value and a high "frozen" value. Here, the melting value has been lowered from 0.5 to 0.2. This is a bit extreme, although individual meltponds may have albedoes this low. A series of values were tried, and this was the best though. The overall Northern Hemisphere ice albedo in summer is now a little unrealistically low, but it's actually better than it was for the rest of the year, and temperatures, year-round, are much improved. There's also a slight average improvement in the Southern Hemisphere ice coverage. There's still too much ice cover for much of the year in the Northern Hemisphere, then too little after the summer melt. Interestingly, the excessive ice in the Pacific really isn't impacted much by this - really, it's good for the temperatures via the albedo change, rather than by the removel of ice. In addition, the tunable parameter of the minimum ice thickness of 0.5m is also reduced, to 0.25m||Both these changes are specified in the UMUI ||
