It shouldn't be cumbersome to make a simple colorbar scale showing the right scale, but it is. </p> http://climatedata.blprnt.com/topic/seasonal-variations-per-areas#post-52 Wed, 16 Dec 2009 13:06:05 +0000 Arenamontanus 52@http://climatedata.blprnt.com/ <p>The radial plot helps, although there is some arbitrariness in where to place zero degrees - put it too far out and everything turns into a circle (and the yearly variations get hidden), put it to close to the centre and winters turn into cusps. That is why I like time-delay plots. But I suspect viewers understand radial plots much better, since it fits our often geometric ideas of the "shape" of a year.</p> <p>The animation really works, but it is hard to see the slow trend. Maybe it would be useful if the plots left a subtle grey track of where they had been, making it more clear that the blue one has moved outwards?</p> <p>I really need to learn R, the plots are beautiful. </p> http://climatedata.blprnt.com/topic/seasonal-variations-per-areas#post-51 Wed, 16 Dec 2009 04:53:17 +0000 blprnt 51@http://climatedata.blprnt.com/ <p>Cool!</p> <p>I think Arenamontanus is doing some similar work:</p> <p><a href="http://www.flickr.com/photos/arenamontanus/4182402460/" title="Suntar by Arenamontanus, on Flickr"><img src="http://farm3.static.flickr.com/2780/4182402460_1acf7a245c.jpg" alt="Suntar" /></a></p> <p><a href="http://www.flickr.com/photos/mgilbir/4182364808/" title="Temperature evolution (North region) - polar plot by mgilbir, on Flickr"><img src="http://farm5.static.flickr.com/4006/4182364808_1dbdb7770b.jpg" alt="Temperature evolution (North region) - polar plot" /></a></p> <p>As I said in his post, I think this radial plot is very effective. </p> http://climatedata.blprnt.com/topic/matlab#post-50 Wed, 16 Dec 2009 04:51:33 +0000 blprnt 50@http://climatedata.blprnt.com/ <p>Very nice.

Mainly the purpose of these images is to get an idea of the scope of the data. I thought it would be helpful to break the records down into monthly sets. Also I sorted the stations by latitude, which groups like measurements together.</p> <p>I want to do some more exports like this focusing on certain geographical areas (N. Africa, for instance) to see if I can identify some trends...</p> <p><a href="http://www.flickr.com/photos/blprnt/sets/72157622978635070/" rel="nofollow">http://www.flickr.com/photos/blprnt/sets/72157622978635070/</a> </p> http://climatedata.blprnt.com/topic/climate-change-visualisation#post-25 Fri, 11 Dec 2009 06:53:17 +0000 Flinklabs 25@http://climatedata.blprnt.com/ <p>We've just put together a 3D globe style visualisation of the data.

Just a quick note on the readings table. If you add an index on theYear, theMonth then the lookups in the code to get the readings for a given year/month will be much much faster. </p> <p>The following sql will do it.<br /> <code><br /> create index date_index on readings(theYear, theMonth);<br /> </code> </p> http://climatedata.blprnt.com/topic/get-to-know-the-data#post-22 Thu, 10 Dec 2009 20:26:24 +0000 blprnt 22@http://climatedata.blprnt.com/ <p>Brilliant.</p> <p>Can you post or send me a screenshot?

There's a fair number of -99 temperature readings, misspellings, etc. It'll take some work to clean it out. </p> http://climatedata.blprnt.com/topic/here-is-the-data#post-20 Thu, 10 Dec 2009 20:05:44 +0000 cr23 20@http://climatedata.blprnt.com/ <p>let the fun begin! </p> <p>just realized i had to clear my cache / cookies to actually download the 9mb file instead of the original! duh. </p> http://climatedata.blprnt.com/topic/get-to-know-the-data#post-19 Thu, 10 Dec 2009 19:35:38 +0000 rockitbaby 19@http://climatedata.blprnt.com/ <p>Thats what I did today.

But how are there readings from the year 1701? </p>
