Notes

-Sample filters on NO, NOx, NOy, CO and O3 were replaced on today 6/30/2020
-Rain gauge is free of debri
-Anemometer propellor rotating smoothly

-NOy converter temperature: 320 deg C 
-Small tree at front of trailer were cut 
-Dangling copper wire at front of trailer was affixed to trailer with metal conduit and grounded to ground
-Found condensation inside ozone and CO sample lines; they were flushed with zero air and insulated with pipe insulation cylindrical strips
