CWOP update.

[DanS]

I see CWOP has updated their Data Status page. It now has a "Wind Vector" field added along with the usual Pressure, Temp, Dew Pt./Humidity fields.

Nice!  Another area to get graded on!

Post a link.  I don't know what page you're referring to.

Greg,
Found it on my normal page that I check for QC.  Added right after baro, temp, dewpoint.

Got it!  Thanks Andrew!    

I'm not seeing the picture on the right (the 7-day).  I'll have to look at that when I get home.  I don't know if the computer here at work is blocking it or maybe it's just not working.

I see a madis rating but not a cwop rating.  Perhaps that's in the works.

Greg,
I see a red x for 7 day as well.  I assume that is because they just turned it on.  I expect in one week from yesterday, the 7 day graph will populate.  Of course since they have the data, they either should have populated the data, or just waited another week to launch if the calculation side of program was not dont yet.  Oh well, we'll see.

Also no checkmark or x's graphic yet for this variable.  Just the thumbs.

Today I'm seeing the little red "x" for the 7-day graph as well. Yesterday I saw both graphs and both had data. Like you mentioned Andrew, perhaps because it's new or just activated and they're still working on it.

Andrew,

I just looked at your graphs and they appear to indicate that your data is about 10° west from their analysis.  My graph is showing about 18° east of their analysis.
I know that my anemometer is not out 18° and I would doubt that you would have such a large error

In both cases the difference is approximately the same as the magnetic declination for our locations.  I initially thought that our ( possible) errors could be caused by one or more of the stations they use for comparison reporting magnetic, rather than true north, but if that was the case our errors would be opposite ( East rather than West).

Could it be possible that CWOP is somehow adjusting reported direction by the declination?

[mackbig]

Perhaps Tom.  Not sure.  have not looked at the analysis too much yet.   I will have to check my anny again.  I think I might have split the difference on mag north and true north for it.  For my lightning I tried to get as close to true north for the strikestar and data analysis compares.  For wind, considering most people stick to 8 compass points, figured close is close enough.  Even at 16 its pretty tight.

I checked my raw data for Saturday, as we had a pretty constant wind all day.   I was close enough to enviro canada site a few km's away.   Of course they only report in increments of 10 degrees and only hourly.  Then there are a bunch of station types that only report to 22.5 degrees. 

I may adjust a bit after I see my qc numbers for a while, and double check my compass vs 10% declination.

ps: 7 day graphic is working today.

Cool, I have two thumbs up!

Hi guys, any reason why i dont get any comparison on mine please

They only do QC compares for North American stations.

that explains that then lol, thanks..

I just noticed this update a few days ago, and I have to say that Wind Vector is far too varied over a short distance, for there to be any proper analysis and subsequent grading of one station's results. Where I am for instance, the terrain varies greatly just between my next-door neighbors yards, and where I am located (We are relatively close together as well). I don't see how this factor can be properly graded for satisfactory results and such. Temperature, Humidity, Dew Point, and Barometric Pressure can all be mapped fairly well, and adjustments can be made in a relatively easy manner. When it comes to wind issues though, are we going to expect people to raise 200 ft. masts in their yards to attain above tree-top level anemometer readings (Such as in my case)? I live in a gully, with 150 ft.+ trees around my yard (As well as my entire neighborhood, and most of my community), and I have my set-up already located 20 ft. above the ground, yet my Vector readings are nowhere near what the analysis is displaying. I have completely unrestricted airflow from two different directions, and 270 Degrees worth of maximum available clearance from high objects. I don't want to get bad ratings because of some analysis which I can do absolutely nothing about.
