Nice fog event last night. The active collector opened at 6 am and about 60 mL of sample collected at 10:30 am. Collector cleaned with soap, water and dried, then blank taken at 2:30 pm.
Finally got the MiniOFS visibility sensor installed at the ISB Greenhouse at UCSC. Logging data to the serial port of a PC with Terminal software. You can see the two lenses, IR source and IR sensor. It is strapped to the ladder going to the highest point on the ISB roof. It is pointing north. The fog has disappeared for now, but is supposed to return tomorrow or Friday.
The MET station batteries seemed to be dying. They were replaced. The tipping bucket was also full, meaning it got plugged. It seemed to occur around the time of the fire (around July 23-24) thus the high amount of ash in the water (see photo). One of the bird spikes was also hanging off the mesh. It was pulled off (that was all I could do without a ladder).
Data were downloaded from MET station and from SFC. Guy wire was tightened on SFC.
We have been getting a sample nearly everyday for the last two weeks!
We have gathered a fair amount of fog this summer and now we’re ready to start testing them.
I acid wash the mesh filters every other fog event and I give a soap and a triple DI water rinse for every fog event.
about 225 mL of fog water collected today. Amazing Fog-ust so far.
Full bottle of fog water today. Filtered 1/2 of it, and 1/2 of the blank, and acidified all four. (unfiltered sample and blank and filtered sample and blank).
The fog catching mesh from the fog collector got an acid bath today on July 27!
