Log entries with a label of rain.
John and I checked the rain gauge at soilb for clogs at about 12:00am. It was clean.
The 2m krypton was cleaned.
UPDATE: The gauge did show a tip when a rain event moved through at about 2:00 pm
and the 2m krypton went to 0 volts.
Have started looking at the comparison between the various rain gauges. In this analysis, I removed [data when the wetness sensor indicated dry conditions?] There have been several major rain events, but not all sensors were working:
Date
understory
ott.pond
tb.pond
wxt.pond
wetness.…
Gordon and I just had this exchange, that I thought should be put in the logbook (even though it relates to an action a while ago):
I'm starting to look at the rain gauge comparison. I note a major event on 7 June that was only seen by the OTT. This caused you to change the WXT settings. For the next 2 days, Tom's daily status messages noted that rain.tb was not reporting, but this comment was dropped on 9 June. I haven't found a comment about what fix was done to get rain.…
Driving back from Jim's, there were drops on our windshield. The WXT and wetness sensors have seen it.
10:30 Upon inspection found the tipping bucket tube at soil.b was clogged with ill-defined organic matter.
Since the funnel was full, I tried to allow this water to be measured (post-rain), but only was able to get 2--3 tips to register. Also, this likely would have been an under-report since the funnel's capacity had been exceeded.
We have decided that checking for clogs should be a regular maintenance task.
We had noticed that the tipping bucket mount was somewhat shaky. I have just secured it by a bit of guying. The bubble level had been out of the outer ring and now is within the inner ring (though not exactly centered).
A storm came in from the north last night. It rained intensely for about 2min while we had dinner in Tuscaloosa. All gauges saw it at about 2145 with totals:
undercanopy: 5.0mm (includes an event earlier in the day)
ott: 3.1mm
new tipping bucket: 3.1mm
pond: 4.3mm
Thus, perfect agreement between the 2 new sensors and general agreement between all.
All systems stayed up, though all sensors stayed wet overnight.
Noticed tipping bucket at soil.b was clogged. Un-clogged tube. All good again.
The rain value from the wxt has been a constant zero:

The current output message looks like so:
0R0,Dm=103D,Sm=0.8M,Ta=20.5C,Ua=94.2P,Pa=1.0072B,Rc=0.00M,Hc=0.0M,Vs=12.8V\r\n
I rserial'd in and displayed the current precip configuration with the "0RU cr lf" command:
0RU,R=00000000&10010000,I=1,U=M,S=M,M=C,Z=A,X=10000,…

4:50 Tom replaced battery with low voltage (~9V) at soil site B (rain). The new battery reads 11.9V
