Topic: New ASOS Temperature/Dewpoint System

That's a useful link I didn't know about. Thanks.
I didn't realise it would show the sites this side of the pond as well.

That goes for me, too

Synoptic Data is a Public Benefit Corporation and Certified B Corp. Not too many companies are in that category. In my current job, and formerly when I worked at NWS and FAA, we work with Synoptic Data. As NWS will no longer support MADIS, Synoptic is taking over. They have a database of global observations that keeps growing.

Some very useful features.
I found the graph util especially useful for comparing local stations:
e.g.

Still exploring

296 complete as of 15 May. That’s about 34%.

I’m curious, when they replace the temperature and dew point sensors are they also replacing the radiation shields?

[CW7491]

Yes. The temperature sensor is placed in an aspirated RM Young shield and the humidity sensor is placed in a passive RM Young shield.
