Did Anders Ångström invent this instrument?Kgrr 14:05, 13 March 2007 (UTC)
 * According to this article about Anders Knutsson Ångström, who is the grandson of Anders Jonas Ångström, he (Knutsson) invented it. I checked out the citation and it links to a google book, although the page cannot be viewed, if you look at the table of contents, it says page 47, which is where the citation leads, is about the Ångström Pyranometer (note that there are 2 topics on page 47, the pyranometer is the second) although there's no way of confirming which Ångström invented it. — Preceding unsigned comment added by Thedoctar (talk • contribs) 19:13, 11 January 2013 (UTC)
