Thanks for catching the typos, somethi...Stormglas,<br /><br />Thanks for catching the typos, something always gets through. ;)<br /><br />Beware that none of what I post tells us anything about MYI volume this summer. PIOMAS gridded thickness data hasn't been released over the summer. The two PIOMAS based plots are for the spring - April to be precise.<br /><br />There is a relationship between area and volume approaching minimum for CT Area and PIOMAS volume. For the date of minimum for both series volume is related to area by the following equation (power trend applied to scatter plot, R2 of 0.93).<br /><br />CT Area = 1.287 * PIOMASVolume^0.5066.<br /><br />In other words CT Area is about 1.3 times the square root of volume.<br /><br />For monthly averages September is:<br /><br />CT Area = 1.35 * PIOMASVolume^0.5064.<br /><br />Which has an R2 of 0.91.<br /><br />I've yet to get round to working this out for NSIDC Extent.Chris Reynoldshttps://www.blogger.com/profile/16843133350978717556noreply@blogger.comtag:blogger.com,1999:blog-1367053740188758246.post-14115891285292647812013-09-03T05:15:47.761-07:002013-09-03T05:15:47.761-07:00Great post Chris, I think an update for minimum vo...Great post Chris, I think an update for minimum volume won't be necessary. The two last graphs contain a typo : volume in in km^3 not km^2.<br /><br />I think it's interesting that volume seems almost independent of area, given the last three years. And even with a cold, cloudy arctic summer the MYI volume decreased significantly, that must almost mean that melt form the bottom is fierce.Anonymousnoreply@blogger.com
