Summary: Rained, Rain, more Rain coming. Swapped Floor 7500, brought in Arduino diffuse PAR test - not much data. Z-cam 1 had condensation inside box, Tower keyboard got wet, did not get Phenocam images of FD data

I arrived at about 12:15. Heavy rain last weekend and still some showers today – I got caught in a thunderstorm with hail and heavy rain. The water level in the pond doesn’t seem to have changed much though. The trees still have some mostly brown leaves. There is green grass coming up in most places.

I removed the Arduino diffuse PAR from the Tower top. The CR10x only saved a day’s worth of data but seem to still be getting new live data from the Arduino. Not sure what the problem was. More testing in the lab.

I forgot to bring the CFM card reader so I could not collect the Phenocam photos. I copied a few photos over the network connection to the CR1000 but it’s way too slow to do more than a few.

I serviced the z-cams, measured the soil moisture, and read the dendrometers. At Liu Kang’s tree I heard about three rolling bouts of thunder to the east. When I was at the far dendrometer trees (#79, #72) I could hear the mixed rain and hail approaching from the south. The laptop was collecting data from the FD chamber and got a little wet. The keyboard at the Tower was out and got a lot wet. Probably should bring a spare next time just in case.

The FD chamber data may be gone. The file I got was just the header and I think I cleared its memory.

The Floor met soil moisture table is missing data but the Floor met table is okay – not sure why. Might need to upgrade that CR23X to handle the two SoilVue probes.

The IRT CR1000 is also losing data on low sun days. The lithium power pack had 3 out of 4 good status lights. A ton load of acorns pushed into that box.

I swapped the Floor 7500: sn 0418 came off and sn 75H-2180 went on.
0418 read: 423.4ppm CO2, 389.9mmol/m3 H2O, 13.8C, 99.3kPa, 99.5SS
2180 read: 430.6ppm CO2, 409.1mmol/m3 H2O, 13.9C, 99.3kPa, 100.4SS
2180 had a relatively large offset in CO2 span when it was calibrated but looks okay compared to 0418 here. I set the pressure coefficients and reset the box.

Z-cam 1 had condensation on the inside of its window. I wiped it off and added two fresh small desiccant packs. It could use a bigger pack next time. I wiped water off all three windows after the thunderstorm.

I left at about 15:30
