Light rain.
RH has been reading -3 % here since last night. Removed unit 015. Goretex sock was intact, a damp black film present on the goretex - probably from dust. This unit is covered with a brown resin where the transducer is soldered.
Brought 015 back to car to let it dry out a bit. Inside of din socket was damp. Sprayed it with some canned air. Put back in unit, but RH still bad. Replaced with 021.
Tom removed Qsoil, ECHO003, which had been reporting intermittently. Replaced with unit 020 which we had just removed from aux playa1. Values look good.
