p.s. Why use an hourly pressure change in the gauges and tables when Cumulus returns a 3 hourly value?

WMO standard is for a 3 hourly trend.

It is possible to also use the standard 9 pressure trend descriptions, especially on the gauges?

Yes, but, A 0.7C/hr trend = 2.1C/3hr ???

It was warming on a negative trend (I missed the "-" on the 0.7C)

Altocumulus

Thanks Both.

At 10:44

3.0C has a trend of 0.7C/hr which is neither a one hour change (0.0) or a three hour change (+2.1).

This ought to be a logical trend showing on localhost displays : Dashboard and Graphs. Legend says C/hr..... This morning I had a positive graph showing negative trend? 0754 : 0.9C 0854 : 3.0C Steady rise : Trend -0.7C/hr 0914 : 3.1C Trend 0.5C/hr Wiki suggests temptrend is over the last 3 hourly pe...

One hour after sunrise and I've maxed at 18W/m2 and recorded 0.6 hrs of sunshine under a relatively cloudy sky - certainly 6+ octas.

How are others finding the sunshine hours recording?

Altocumulus

Indeed.

On a cloudy day I've managed to record 1.2 hours of sunshine!

Back to the leaflet that accompanied the sensor. Keep calibrated, at least yearly ( as Davis' experience is a drift of 2% annually) is the advice without further explanation...

Hi Mark, No local site that I'm aware of and Google isn't helping identify any. The sensor is a recent addition and is the standard Davis accessory for the VP2. It's showing 16 at the minute under an overcast sky. I'll have to have another look at the leaflet that came with it, though I remember it ...

These are global irradiation sensors. If they were direct irradiation sensors (= v. expensive) then you would not over read like that. Plus an expected value of 48 is quite low, so the errors are bigger. But as I said you need to look at the graph to make sense of the numbers. You also need to cali...

OK - It didn't seem logical to be experiencing almost twice the theoretical maximum.

Altocumulus

On MX Dashboard and also on website - mouse-over dial produces the following message in the balloon..

Solar Radiation 93W/m2 - 194% of maximum.
Current theoretical max reading 48W/m2

Had to double check, but yes lat/long correct in the Settings

Cumulus generated web template at source with new data, whilst Cumulus MX uses a static one on the server. In Cumulus I used the standard images, and tags, onto my own web template. The Template started as a txt file, with Cumulus generating it and renaming as php. I used a short snippet of php scri...

1500 - humidity 15%! Changed channel on ISS to 4, from 1 (default). Changing channel on the ISS is easy. Changing channel/station on the console is fickle. It took a few times to take and state it is receiving from station 4, as it kept reverting back to 1. Finally it accepted the change to 4, and i...
