There was a large fire of some sort to the west of Currie, with a plume of smoke spreading eastwards without rising very much. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=15526#post-200634 Fri, 02 Oct 2015 08:10:27 +0000 acsimpson 200634@http://citycyclingedinburgh.info/bbpress/ <p>The western ring road was very smoky both on my way out at 6 and home at 10 last night. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=15526#post-200632 Fri, 02 Oct 2015 08:07:24 +0000 crowriver 200632@http://citycyclingedinburgh.info/bbpress/ <p>From Wiki:</p> <p>"Photochemical smog was first described in the 1950s. It is the chemical reaction of sunlight, nitrogen oxides and volatile organic compounds in the atmosphere, which leaves airborne particles and ground-level ozone.[14] This noxious mixture of air pollutants may include the following:</p> <p>Aldehydes<br /> Nitrogen oxides, such as nitrogen dioxide<br /> Peroxyacyl nitrates<br /> Tropospheric ozone<br /> Volatile organic compounds</p> <p>All of these harsh chemicals are usually highly reactive and oxidizing. Photochemical smog is therefore considered to be a problem of modern industrialization. It is present in all modern cities, but it is more common in cities with sunny, warm, dry climates and a large number of motor vehicles.[15] Because it travels with the wind, it can affect sparsely populated areas as well."</p> <p>Yum! Suck it up, fellow asthmatics! :-( </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=15526#post-200631 Fri, 02 Oct 2015 08:02:52 +0000 crowriver 200631@http://citycyclingedinburgh.info/bbpress/ <p>@Nelly, that would explain the smell of smoke as my train headed into Edinburgh yesterday evening. Very strong smokey smell in Waverley too, mingled with diesel fumes. Lovely! </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=15526#post-200626 Thu, 01 Oct 2015 23:54:14 +0000 chdot 200626@http://citycyclingedinburgh.info/bbpress/ <p>I blame VW. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=15526#post-200622 Thu, 01 Oct 2015 22:58:55 +0000 KeepPedalling 200622@http://citycyclingedinburgh.info/bbpress/ <p>Interesting comments thanks. Also two tuesdays ago I was high up near Haddington and again had a similar clear view over the Forth over a yucky brown layer. Almost felt wrong to pedal down into it back towards Edinburgh. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=15526#post-200618 Thu, 01 Oct 2015 21:33:51 +0000 gembo 200618@http://citycyclingedinburgh.info/bbpress/ <p>Muck spreading is my other theory, though admittedly even I don't buy that </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=15526#post-200617 Thu, 01 Oct 2015 21:25:21 +0000 ih 200617@http://citycyclingedinburgh.info/bbpress/ <p>"I had a lovely ride today,thank you." Well, yesterday actually and looking back from the unclassified road that runs in a straight line from Dalkeith to Pathhead, you get a great view of Edinburgh and the Pentlands.....and a thick pall of brown smog blanketing the whole city. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=15526#post-200613 Thu, 01 Oct 2015 21:03:40 +0000 Nelly 200613@http://citycyclingedinburgh.info/bbpress/ <p>I was on the M9 about 12.30 and there was a huge fire and associated smoke plume on the western pentlands. Smoke was headed toward Edinburgh. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=15526#post-200608 Thu, 01 Oct 2015 20:42:10 +0000 gembo 200608@http://citycyclingedinburgh.info/bbpress/ <p>See other thread about my trip to Dunfermline, huge fog sitch.</p> <p>Coming back from Fife today there were great views to the pentlands where there were some fog patches or lower lying cloud not brown and not linked to LIDL </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=15526#post-200601 Thu, 01 Oct 2015 20:25:41 +0000 Klaxon 200601@http://citycyclingedinburgh.info/bbpress/ <p>I mentally remarked on the haze hanging over Leith Walk cycling back up from Lidl earlier on as well. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=15526#post-200598 Thu, 01 Oct 2015 20:11:11 +0000 SRD 200598@http://citycyclingedinburgh.info/bbpress/ <p>Walking home from lidl this evening, we were definitely struck by the murk. MrSRD thought it reminiscent of rubbish being burned in Khartoum. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=15526#post-200594 Thu, 01 Oct 2015 19:50:01 +0000 crowriver 200594@http://citycyclingedinburgh.info/bbpress/ <p>Not just Edinburgh. Also spotted over the Tay during the sunset this evening, mostly to the west and south of the Tay Bridge. </p> <p>Perhaps the high atmospheric pressure, coupled with clear skies, blazing sunshine and little wind has created a cloud of photochemical smog? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=15526#post-200592 Thu, 01 Oct 2015 19:33:48 +0000 KeepPedalling 200592@http://citycyclingedinburgh.info/bbpress/ <p>This lovely weather has given some lovely clear views, but when I am up in the hills it is rather disconcerting to look down on what appears to be a layer of brown pollution covering Edinburgh and all around. Has anyone else noticed this - do you know more about it? </p>
