Title: Barometer readings on Met Service - Your Weather Observation
Post by: choc-a-holic on January 28, 2015, 12:18:50 PM
I have watched with interest the increase in the number of weather stations being displayed on the Met Service's - Your Weather page.  If I look at the Nelson/Tasman area - http://www.metservice.com/towns-cities/nelson#!/your-weather (http://www.metservice.com/towns-cities/nelson#!/your-weather) today the Barometer readings range from 1009 to 1027.  Today is a typical summers day with the typical sea breeze blowing and a few white puffy clouds hanging around the hills.  I would not have expected such a difference in the readings.  The reading at the airport is 1013 which I would hope is accurate and I would have expected most stations to be reading this all very close to it.  My station is reading the same.

The temperatures vary considerably, but I expect that as those inland in Brightwater and Wakefield and in valleys are sheltered form the sea breezes.

Whoops just noticed that this post should be in climatology and environment.....sorry cannot see how to change it now.

Our map is the same. The odd station either too high or too low. Likewise the data summary.
Station owners dont realise out of the box the baro needs calibrating.
As most here will know I spend a lot of time emailing re their baros and nagging trying to keep us all in line.
Its on going as it only takes a change of batteries to throw things out again.

I love central Taranaki on the metservice map at present 1055 !!!!!!!!
I would be fair nagging that owner :)

Cheers

Jenny I understand that as I was one of them did not do it or never understood but do I change it back after calibrating or do I keep it on there?

Once calibrated with neighbour stations then you leave it.
Just check now and again that it is still correct by checking against those stations near you.
If you change batteries, chances are it will be wrong again.
So check with neighbours and calibrate again if needed.

While this is still off the topic, it has relevance to Choc-a-holic's post so I may as well continue here.
I decided to join up with the WOW Met site today and due to finger problems put in the wrong co-ordinate for Latitude (1 degree out which put me into the Pacific Ocean). I quickly picked up on this and attempted to edit the figures. The form allowed me to do this, but when I re-loaded the station it still showed the old coordinates. So I naturally tried again.... same result. Eventually I found that 2 new stations had been created with different ID numbers as a result of the editing. I have suggested to UK Met that they review whether this is an intended consequence. I guess this may serve as a warning to get it right first time should anyone else venture into this territory!

WOW has a forum, but you have to have a Google account and even then you have to apply to join the forum and be approved by the administrator which is a pain.

Tony, yes I have run into a similar problem on the WOW site.

There is no facility for a user to delete a station's incorrect position, or a secondary station that the user (inadvertently) set up and needs to be deleted.

I found somewhere on the WOW site to give feedback but I think it was for their website in general so I don't know if my message (about deleting an erroneous site of mine) will get through to the proper person. I do not spend much time on the WOW forum but someday I will and perhaps I can find the proper method for making corrections.

Cheers from 9 degrees cold Masterton.

not just baro readings that are out
also temperature (too high), from poorly sighted or sheilded sensors
