"Blocky" Pressure Graph

Post by geoffw »

Any idea why my pressure graph is looking so blocky as compared with temperature for example?

Oregon Scientific weather stations have a pressure resolution of 1 mb. The temperature resolution is 0.1 C.

So it is a 'feature' of the station then?

It's the stated specification of the pressure sensor - it can only ever be a whole number of mb. The graph reflects that.

I really don't like the 'blocky' look of the pressure reading, though I quite understand the reason for it. Perhaps when the charts are next looked at - some way of smoothing it's output would be much appreciated. I've obviously been spoiled by the Fine Offset reading.
