Had fan on LML system (RH 91) set backwards – so no sample even though doors opened.  No apparent wetness on ground in morning. UCSC rain sensor system did not open.  Tested both systems and they work properly.  Rinsed out LML collector and jar with DI and reinstalled.

Odd post sunrise fog moved in after a really hot day.

Running 2 fog collectors on ISB roof.  One has the rain sensor with mini-collector funnel, connected to UCSC network (email me for the http address to access weather data and images of jar).  The other has the old 2014 Fogon.py program with 91% RH cutoff.

The 91% RH triggered the 2014 system (doors open).

Updates on a few samples and the close down:

 

9/12/14  11:00 am :  full sample present, yet very dirty.  Considering how dirty the entire system was, I am unclear if it had been cleaned the previous day by one of my students.  Aliquot also taken.  Sample was acidified on 9/13.

9/13/14  very small amount – only enough for an aliquot.  System cleaned and a blank taken.  Blank was acidified that day.

9/14/14  11:15 AM 50 ml of sample  – bugs were removed from water and it was acidified that day.

9/18/14  2:00 pm  about 100 ml present.  Not sure when it may have been collected, since machine had been open for 3 days.  Aliquot taken and system powered down.  Sample acidified 9/18.
