I couldn't find a comment over there - all I could find was an advertisement from RP Sr., listing a few of his papers.

Their model is not a physical model."</i><br /><br />Ummm ... you should actually read the Myhrvold paper, Gradie's comments and the WISE and NEOWISE papers describing the calculations being made. The fact that NEOWISE is not *completely* a physics based model is really not important to the points Myhrvold raises that Gradie comments on. <br /><br />The NEATM equations are still used, thermal emissivity is assumed to be 0.9 for all asteroids - regardless of composition, and reflected sunlight in Bands W1 & W2 is assumed to be negligible (this is the misapplication of Kirchoff's Law).<br /><br />The reflected sunlight issue does not apply to either IRAS or AKARI because their lowest wavelengths do not contain much reflected sunlight. This is not true of the lower wavelength bands on WISE/NEOWISE. But rather than accounting for the reflected sunlight, NEOWISE often just ignores the data from bands W1 & W2 when calculating thermal emissivity.<br /><br />Kevin O'Neillhttps://www.blogger.com/profile/06692943768484857724noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-17374089816403006492016-06-01T19:41:38.457-04:002016-06-01T19:41:38.457-04:00One would have thought that when one gets "cr...One would have thought that when one gets "cryptic" answers to questions from an expert in a field you know little about, the correct response is to educate yourself rather that rush to write a paper (and a press release!) charging incompetence and possibly fraud.KAPhttps://www.blogger.com/profile/11189506171267750391noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-12339418930093477782016-06-01T11:49:47.135-04:002016-06-01T11:49:47.135-04:00Eh, RP complaining about RC comment moderation yet...Eh, RP complaining about RC comment moderation yet on his blog he didn't even allow them...Anonymoushttps://www.blogger.com/profile/09300071568901157514noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-24503136829655988582016-06-01T09:35:38.435-04:002016-06-01T09:35:38.435-04:00Roger Pielke Sr.'s tweets, blogs and other inf...Roger Pielke Sr.'s tweets, blogs and other informal commentaries have often been significantly more contrarian than his published papers. And he consistently directs his scorn at leading climate scientists rather than criticizing the slipshod work or weak claims of 'skeptics'.<br /><br />Since Pielke is retired and Gavin Schmidt is anything but, Pielke has more than enough time to do his own work instead of trying the "Hey, kid!

Kevin O'Neill: Yes, and so...Plait, not Platt.<br /><br />Kevin O'Neill: Yes, and so what? Their model is not a physical model. They have explained why: Asteroid surfaces are complex and not well understood. Thus, the correct parameters for a physical model are difficult to know. Whereas an empirical model, calibrated against hundreds of samples, works to within 10 or 20% in all cases tested.<br /><br />A tremendous amount of astronomy is based on non-physical empirical models. The radiation spectrum from cold galactic dust, for example. Which is fine so long as you don't try to push the model too far, as the good folks at BICEP2 learned not too long ago. Physical models are preferred of course, but only if you can determine the parameters.
