However, the services obviously only have a finite number of weather stations whose location would not exactly match what I queried about. So i guess the different locations of the weather stations used probably was a factor in the differences.<br /><br />The Weather Underground service publicly claims to be using weather data coming from amateur stations, but the others claim to be using professional data only.<br />Brian O'Donovan (BOD)https://www.blogger.com/profile/10652457466416412942noreply@blogger.comtag:blogger.com,1999:blog-7354418957262058264.post-6978587971492072542016-12-29T18:53:40.744+00:002016-12-29T18:53:40.744+00:00Hi Brian, I used to be a weather forecaster and a...Hi Brian, I used to be a weather forecaster and a couple of points I would make regarding temperature are: <br />1:Temperature can vary significantly over short distances. City center temperature is likely to be different to the airport for example, or any place near the water is going to be influenced by the water in onshore flow situation. So you would need to find out what stations are used to verify each forecast and compare only like with like.<br />2: Measurements should also be made using quality approved equipment that is set up according to accepted standards. Equipment used by Met Eireann could be trusted while a private weather station may not be up to standard.Anonymoushttps://www.blogger.com/profile/00230951485791591948noreply@blogger.com
