Weather Quality Report Wind Speed "errors"
« on: September 11, 2019, 11:48:17 AM »
I get the emailed quality report daily for my station C4114.

The "Speed knts" column has crazy errors showing in bold, in the thousands of units.

Here is a small sample from today:
Date                   UTC   Alt (mb)     Temp F          DewPt F            Wind Dir    Speed knts

10-SEP-2019   0150   1024.6   -0.69   54   +2.74   48   -0.17           360   +65   0.9   +3258.9
10-SEP-2019   0155   1024.5   -0.59   54   +2.74   48   -0.17              0   +43   0.0   +4458.2
10-SEP-2019   0240   1023.8   -0.52   54   +2.94   49   -0.88           360   +66   0.9   +1936.8

My data on MesoWest looks good with all "OK".

Anyone else seeing this and/or know what is going on? I don't think that my wind speed errors are in the Mach range... :shock:

Same here on DW9356.  I am failing 49/49 in the "Wind Dir" and the "Speed Knts" columns.

I should add that the 3-day Madis report shows this for wind (FW4751):
https://weather.gladstonefamily.net/site/search?site=F4751;Get%20information=Get%20information;days=3#Data
   
MADIS
rating   MADIS rating 73% QC OK
Sensor fails following checks:
L3 Spatial Consistency (with this link describing that check: https://madis.noaa.gov/madis_sfc_qc.shtml).

I chatted with Philip Gladstone. Here is what he had to say.

It is unclear what is going on. MADIS is certainly generating crazy wind analysis numbers.... I'm think that I'm just going to disable it (the wind speed) until further notice. However it also is missing other data (not consistently)...

Thanks for the update from Philip as it continues to be a problem for me.

I don't check CWOP every day, but I was startled yesterday when I did.

Got a big, "Thumbs Down" on my wind reporting, though all my numbers looked fine to me.  I noticed that the red "analysis" line was incomplete.

I will stop worrying about it, it's "them not us".
