Title: Some interesting facts about weather Post by: Roman White on May 09, 2009, 08:39:43 pm I have just found an info about how the illuminance of environment changes if the sky is 100% covered with clouds: Cb 0.2 Ns 0.21 St 0.24 Sc 0.31 As 0.48 Ac 0.71 Cu 0.48 Cs 0.65 Ci 0.72 (comparative to clear sky = 1.00) P.S. Hope to see (or to add myself) some more interesting facts in this topic |
