I don't thin...Ford: Interesting link, thanks. <br /><br />I don't think for a second that UAH (or anyone) fiddles the data. I think they adjust it as best then can. Satellites drift, for one thing, in a way that isn't predicatable. One such factor are solar storms that temporarily expand the atmosphere, which creates drag.David Appellhttps://www.blogger.com/profile/03318269033139447591noreply@blogger.comtag:blogger.com,1999:blog-28837843.post-53727850447817822212012-03-30T11:00:30.425-07:002012-03-30T11:00:30.425-07:00I've been logging the "discover" dat...I've been logging the "discover" data for a time and did this post some time ago:<br />http://climateandstuff.blogspot.co.uk/2011/11/just-how-good-are-satellite-derived.html<br /><br />Spencer says the discover page is virtually worthless:<br /><br />Roy W. SpencerDec 21, 2011 03:59 PM<br /><br />If you would have read the disclaimer at the Discover website, you would have realized you can't compare the daily, automated, quick-and-dirty data averages there with the fully intercalibrated, quality-controlled UAH dataset that we update every month. <br /><br />The Discover website data are meant to give a rough idea of how the latest month is shaping up compared to the same calendar month a year earlier, that's all.<br /><br />To which I replied<br />thefordprefectDec 25, 2011 05:54 AM<br /><br />Roy The data is a couple of degrees adrift from satellite to satellite. This is not good! Why bother even giving the data if it so far out to be worthless?<br /><br />Although there is a statement ofn the discover page about accuracy it says nothing about adjustments. It says nothing about where similar but corrected data can be obtained. <br /><br />All-in-all this is a poor answer to my criticisms.<br /><br />If you can correct one series from sattelites , why not all. Or are the corrections too complex for a computer!!!<br /><br />Please give a link to the adjustments made and data for similar altitudes that are approved by yourselves.<br /><br />========<br /><br />How can AMSU data be better from the same data?<br /><br />Does Spencer, or one of his minions, individually fettle the data by hand? If a computer is used then why cannot the same corrections be applied to the "discover" data?thefordprefecthttps://www.blogger.com/profile/07210786222021457913noreply@blogger.com
