[wxqc] Meso West

[Sam Drinkard]

Probably the wrong place to ask and or solicit any technical details, 
but perhaps some of you other have seen or see the same pattern I'm seeing.

Some time back (perhaps 2 months or 3) I did my very best to tweak all 
the instruments based on long term averaging of the data from two ASOS 
stations, plus a couple more within my "spatial zone".  I think what I 
wound up with is a respectable setup, based in part on the graphs 
supplied by Philip Gladstone (thanks Philip).

In looking at the Meso West data quality (regression) it appears about 
the same time I did these tweaks, the regression started deviating from 
the baseline quite a bit more.  I don't recall if the scale changed and 
I'm seeing a lower range scale, but if you look at the lines, they are 
all over the place.  I just wonder if their software is somehow picking 
up "trash" or if their algorithims are vastly different from anyone 
else.  For a long time, the 3 parameters, DP, Pressure and Temp were 
hugging the baseline pretty tight.  Now, all of them are all over the 
place.  I know it's not a big deal, but its an annoyance to me to see 
results that make me think I could do better!  Here's an example...

I have no idea what the units are from the zero line.  I guess they are 
just ones.  Irritants like that are what make us strive for perfection I 
guess.

Any comments on ya'lls regression or other aspect of the M-W pages?
