Summary: Stations 1-4 operational

        , ISU staff (Kris and Dan) serviced Station #4 around 11:45 CDT to update new tilt correction angle

         An updated tilt correction was performed after having moving the sonic cross beam to replace the krypton hygrometer on July 5;        5  
         likely Likely morning fog event, nearby towns had visibility ~0.5 mile
         daytime Daytime continuation of light winds from N to NE, warm, muggy conditions
                     
                       
Vdsm: 13.5-13.8 V during day, down to 12.3 at night
P: ok
T.2m: ok, stns 1-3 give erroneous data from 3:00-10:00 because of the morning moisture;
      before dew/fog set in site 1 > site 2 (1.5 degrees) stns 3-4 also reading about 1.0 degree cooler than stn 11    
         
RH.2m: 90-100% nighttime; 65% day
       stns 1  5-7%RH lower than stn 4, stn 2-3 close together
       erroneous data from 3:00-10:00 as in T.2m
H2O.2m: similar pattern as RH.2m,
        erroneous data as in T.2m     
           
Wetness: slight wetness the evening of July 5 (19:00 CDT) dew formation occurring from 22:30 July 5 to 7:00 July 6
         sensor dry by 9:00 CDT

...

RH.10m: ok, similar occurrences of bad data as in T.2M
        stn 4 has few%RH lower than stns2-3 from 17:30 to 19:00
           00      
H2O.10m: ok  see comments with RH.10m        
Spd.10m: ok, late night jet possibly enhancing wind speeds at all sites from 23:00 July 5 to 3:00 July 6;
             very little wind at all sites from 4:00-5:00 before increasing again (another cascade of LLJ energy?, what were the turbines doing?)
Dir.10m: ok, NW to N winds in night/morning; N to NE winds much of daytime

...

w'T' :  ok, stn1 larger sfc cooling whereas other stations ~ 0 during 0:00-2:00
w'h2o': ok, 
h2o'h2o': ok,

kh2o'kh2o': not ok; late morning separation from stn 4 > stn 2 by factor of 2
