Weird wind data
« on: March 26, 2023, 11:56:27 AM »
I'm not sure exactly when it started, but I have never noticed this sort of wind data in the past - where Gust and Peak Wind numbers are nearly identical.

I don't feel like the current data is right. It's possible that the change happened when I went from the Davis USB logger to the WifiLogger2... ?

My configuration differs greatly from yours, but I'll comment on a somewhat similar difference.
In my case I have a Davis VP2 reporting from the console to my PC running original Cumulus through a Davis dongle.

Sometimes my PC is not downloading the dongle continuously (I forget to restart Cumulus after doing a maintenance exercise, most commonly).  After I restart Cumulus it downloads the missing hours from the dongle, but for those hours the gust peaks are materially different than they are for the hours when Cumulus was watching the data live.

Not everything that looks at peaks is recording the same way.

I'm quite sure WU graphs looked much more realistic before but now mine look just like your images. HI and GUST are identical.

But the table does not show the same. The table is more realistic.
