About 9:30 this morning (10/20), Sebastian changed the battery at NNE, in an attempt to solve the (somewhat) erratic data reporting from this barometer.  Now I see min/max dTs of 0.73/1.31, which is somewhat better though still a larger range than any of the other crater barometers.  Sebastian did note that there was a bit of water in one of the power connectors.

We have not seen a big outage since the event 3? days ago, which caused us to pay attention to this sensor.
