Re: Seguimento Europa 2010
You just don't get it. The upward trend for the next 100 years will be greenhouse warmingonly and so is the upward trend starting from 1977 or so.
You seem to think that UHI rises in a linear way...You should have read the studies I handed you earlier on. The rise is extremely steep from, say 100-10000 people and than abates rapidly.
The 0,3 K rise on its own for one observatory that has been influenced by a city surrounding it for more than hundred year quite simply i sno indication for anything on its own. You must relate this rise to other, rural and urban stations. That was not my point, the point is that this site is influenced over the whole period in the 1985 study and that is why their remarks are unsubstantiated They should have related the fall with other stations, they could not have known that SO2 could be one of the components overpowering the greenhouse rising trend. The UHI trend was probably assumed to rise and rise and rise while the city got bigger, but it doesn't work that way.
Larissa: don't know, don't care. Tablada...did you read what I wrote? I have the same problems with that station and have said so all the time. I also concluded that Athens without a heatisle effect woul dbe very warm. Seeing the influence of the effect on the city, somehwere between 0,4 an 3,7 depending on where you are at day in the warm seasonmakes one wonder how big it is at night. At night, the effect is bigger in general. But this also puts the Athens AP station into perspective. As I thought, the difference is not (only) related to the geomorphology of Attica it has indeed a lot to do with a big city and many suburban areas in the Attica region.
You can say that about Sevilla, but you cannot say the same about the Guadalquivir region. You can find loads of rural stations there and they show you the same temperatures as Cordoba. On the side of the Guadiana river it is the same: many rural station and no cities of any size to speak of, bar Badajoz, Elvas and Merida. Talavera airport is 15 km east of the city though..
So we can conclude that there is ample scientific work to strongly doubt Athens and any station in it to measure without a noticable UHI effect. You cannot say the same of the Guadalquivir/Guadiana region.
Elefsis...I repeat, is suburban. Every study I read is clear. Suburban areas are affected by heatisle effects. Elefsis has some exceptional temperatures at times. In part becuase of its situation but as a suburban area it is only logicval to expect a human, urban influence aswell. Just like Sevilla and Larissa (if you say so).
Very nice long analysis.Impressive but I am not stubborn(well maybe biased slightly since hey I am Athenian born and bread) however I have presented you two studies SPECIFICALLY on the temps of the Observatory.
You were the one to attack the Observatory station and I simply gave you the exact values of the temp increase!For 1985 paper the increase in 0.3 against the whole record.
In the latest one a ''significant increase'' of hours over 30C is observed with no real idea if this is the normal cyclic pattern of temp changes.
If you want to ''attack'' this PARTICULAR station do it with exact figures pertinenent to the particular station ONLY and attributable clearly to UHI.Have you done this?I did not see anything apart from generic studies of god knows where in Athens.Again the Observatory station is on a hill and plus you constantly avoid acknowledging Athens basin extreme geomoprhology!I guess it suits you this way
Most importantly why change direction?I am waiting on something pertaining Elefsina station per se!!Btw remember Elefsina is exactly the same with Tablada and Larissa airports in terms of proximity of building...You know what?Elefsina kicks some serious ass!I am sure you know this already.Now care to explain this as well.Bsc we in Greece are still trying!!
