Then there's the Høvringen station. The coordinates point to the roof of this sewage facility. There's a warning sign saying they regularly will be burning gas coming up through pipes in the ground.  ' It's hard to tell the exact location of the weather station, whether it's actually on that roof or not. It does read extremely high average temperatures however, both during the day and night, despite being just a stone's throw away from the sea. I'm mostly just disappointed that despite Trondheim getting like 5 different new stations in the last decade, Trondheim still doesn't have a good station to represent it. The vast majority of Trondheim and its population is above 80m ASL though so in the regard the Voll station is a good station for representing the average climate. But they need a proper and reliable station at low altitude too. If I were Meteorologisk Institutt, I'd keep the Voll station and Skjetlein station, move the Ranheim station to any of the larger green spaces nearby, and change the Lade station for a station in Gløshaugen to represent the city center. They've already got a sun recorder there so why not put a temperature station there as well. It'd be a great UHI station placement. |

In May 2020 Drammen got a new station at Olleveien.    It's a little bit inland of the main core of the town, so it isn't affected by UHI as much, but it's farther inland, it's only at 54m ASL, the radiation shield is tiny (looks less than 12cm in diameter), and while it's on a heavy slope, the slope is south-facing so all in all highs should be pretty warm compared to the main core of Drammen, and lows should be very mild despite there not being as much UHI. Right? Well no. Apparently highs are consistently 2-3'C colder than every other station, and lows 1-2'C colder.  The other stations from west to east: Orkidehøgda, Olleveien, Berskog, Bangeløkka and Sletta:  |

I noticed google updated their streetview images around the official weather station in Gothenburg...   I sent an email to SMHI asking then whether they're using some form of replacement station or if the one in the pictures is actually the one that's been used lately........ |

Heathrow airport surely isn't representative of London.

Did you get a reply to your email, Babu?
If they are actually using that, that is mortifying.

 They're saying it was in October 2020, that there was a short period when the weather station was surrounded by blocks and that SMHI contacted the traffic agency about it as soon as they found out, and the traffic agency then sent pictures of the station's surroundings to SMHI that looked significantly better. They concluded saying the situation shown in the google street view images was dealt with, and never lasted for a very long time anyway. Seems to me there has been construction work going on around the station for quite some time now and that SMHI should consider maybe switching the location to somewhere where there's sure to actually be grass around the station.. |

Sounds like a bit of Boteving on their part...

Just found Copenhagen's weather station. Great UHI placement.   Confused why they decided to place the station inside a hedge though...   |

Sydney Observatory Hill. It's the worst place to have a weather station. And I've always said this. It's one of the most wettest spot in Sydney as it is on an exposed location in the Sydney Harbour -- Well, that's why they have the word "hill", so it is susceptible to rain and winds. It is the most rainiest spot in Sydney (during heavy rain events, it's always Obsv Hill that records the most rain, naturally so). It is also pretty mild. Most of Sydney will be around 38C-42C, and the Hill will only register a reading of 32C. How does that represent a city? Also, nobody lives in around that part of Sydney, unless they're millionaires or they're tourists in hotels.  Sydney Airport should have been the official weather station for Sydney, as it's a nice compromise between the hotter inland suburbs and the milder coast.  |

Obs Hill is representative of the CBD and the eastern and north eastern suburbs though... and with more than 150 years of continuous records they ain't gunna change it. I don't really think the Airport is representative of the greater metropolitan region either... somewhere further west like Bankstown or Canterbury, Parramatta or Sydney Olympic Park is better... but the thing is, such a huge metro area is always gunna have differing climates within the region. Most AU capitals are the same.. they are all coastal cities with a big difference between coastal and inland AWS sites Up until reasonably recently the Sydney forecast was always dual the Obs Hill site and Liverpool site out west. |

An extreme example that I know of is Al-Bahah city in Saudi Arabia. The airport is 800 m lower than the city, and located about 45 km to the northeast.
200% unrepresentative.

Eastern suburbs are more proximate to the Sydney Airport (after all, the suburbs around the airport are under the "eastern suburbs" umbrella). Inner west Sydney (just southwest of the Harbour) become more similar to Canterbury's climate station. I wouldn't say the Hill represents those -- The observatory hill is its own microclimate, and I'm sure inner city suburbs like Surrey Hills become more similar to either the airport or Canterbury. They can ditch observatory hill already -- I mean they can still use it, but only for the harbour. They shouldn't represent Sydney with it. Btw I didn't say the Airport is a good representation of the greater west. I said it's a good compromise, as it can register pretty high temps that the west does, whilst it can also be pretty mild like the CBD. So it's got the best of both worlds, AND it has "Sydney" in it. Moreover, many climates in the world have their airport stations representing them. |

Denver. The airport is 18 miles away from downtown and way out on the plains surrounded by farmland. The airport is several f colder than the representative Denver Water Department station, especially cool season average highs. Also 2” drier due to being farther from the mountains yet 10” snowier.

The last few posts are making me wonder why some cities choose to have their official station at their airport, while others have it in the city centre. Like are there any factors behind this inconsistency?

The last few posts are making me wonder why some cities choose to have their official station at their airport, while others have it in the city centre. Like are there any factors behind this inconsistency? Cities ( if they have a long term POR ) are subject to UHI influences that skew the data even more than the natural warming trend of climate change. The trouble with many airport sites is that they are perceived as unrepresentative of built up suburbia/CBD sites. UHI is a thing... eg Melbourne, AU moved their official reporting site ( since the 1860's ) about 1.5 klm due to the UHI influences on the MRO ( Melbourne Regional Office ) location to Olympic Park in 2015. Even AU country towns have gone to Airport sites as opposed to the older Post Office sites located in town back yards and with manual observers and recordings. AU still has some manual observer sites in remote outback regions, but all newer observations ( mostly at Airports on the outskirts of towns ) are from AWS instrumentation. |

The AU capital cities don't have their Airports representing them other than Darwin and Canberra.... and Darwin's is since 1942 after the Japs bombed and destroyed the Post Office. and re Canberra, since 1939 at the Airport... prior to that, the records were from Acton, 1921-1939. |
