GHCN has spread then fairly evenly, but also thinly.<br /><br />I'll do a plot that colors the cells according to number.<br /><br />Thanks for the kind words.Nick Stokeshttps://www.blogger.com/profile/06377413236983002873noreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-15734564204482772182011-09-09T04:14:52.953+10:002011-09-09T04:14:52.953+10:00Hi Nick,

As is often the case when data is presented clearly, you get ideas for follow-on questions. In my case, I am curious whether you are in a position do do statistics on your data sets to assess "box quality". For example, you could do exactly what you did before, but calculate coverage of boxes that have at least ten stations in them. Obviously, in those plots, the effect of the reduced number of stations will be somewhat more pronounced. My ten stations minimum is not based on any deep knowledge. The amount of variance between the stations in a typical block should govern.Will Kernkamphttps://www.blogger.com/profile/06138290092692260411noreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-15073793659207741262011-08-06T11:02:27.333+10:002011-08-06T11:02:27.333+10:00Thanks, Jeff.

Turns out some researchers would like have it. anyway<br /><br />http://stevemosher.wordpress.com/2011/08/05/chcn-canadian-historical-climate-network/<br /><br />WRT to SST in the SH:<br /><br /> if you look at ICOADS data (raw) in the SH ( an animation) you can see that the coverage has seasonality in it. beats very nicely. I have that work around here somewhere. I think I showed it to peter webster.. so I must have it somewhere..
