It might account for some of the rate of increase in Atlantic OHC.<br /><br />Trends in Saharan dust and tropical Atlantic climate during 1980–2006<br />http://staff.washington.edu/grfoltz/amo_dust4.pdf<br /><br />DBAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2220966763638300672.post-77709415820763466492010-07-18T15:43:18.198-04:002010-07-18T15:43:18.198-04:00Bob K: Thanks for looking into it.

I also doubt they have any noticeable impact and that they're simply a leftover from the early attempts to reproduce global temperature without SST data.Bob Tisdalehttps://www.blogger.com/profile/15462377647970214137noreply@blogger.comtag:blogger.com,1999:blog-2220966763638300672.post-59015799172535341722010-07-18T11:28:16.324-04:002010-07-18T11:28:16.324-04:00I looked at ship N 30N 140W using the giss mapping...I looked at ship N 30N 140W using the giss mapping tool with parameters set to 250 km. radius and June 1948.<br /><br />Ship N is halfway between Hawaii and California. It is being used as a land station. The anomalies shown in their data files for 31N 141W are...<br /><br />Land 0.6158<br />SST 0.5189<br />LOTI 0.5749<br /><br />I assume the other ships are used the same way.<br /><br />Ship N is over 1800 km from both Hawaii and California and so would only affect the coastal surface anomalies to a minor extent with a 1200 km radius. The other ships may be closer to land though. They might have a somewhat more significant effect, though I doubt it amounts to much in the overall scheme.Bob Khttps://www.blogger.com/profile/11864247983108770885noreply@blogger.com
