Summary: Regular data collection/cleaning, tall grass on levee roads, short power outage last week, HMP not working--fixed

West Pond

Robert and I arrived at 12:40 PDT. It was sunny with some cirrus clouds, warming up since we started the day at Gilbert Tract. Still only brown vegetation visible in the wetland, although most of the other sites have green reeds starting to come up. The grass on the interior levee road is very tall, about waist height—made for interesting footage in the back-up camera when reversing.

There were some ants and eggs in the met box—we left them some mothballs. The staff gauge read 69cm.

I downloaded met, cam, picam, and USB GHG data. There was a short power outage from about 00:00 to 03:00 on the morning on 2023-04-14. The HMP155 stopped working after the power outage, but everything seems to be fine after a power cycle (AirT=26.4C, RH=25.3%). There are no Canon camera photos since the power outage, but the picam photos should be complete.

Robert cleaned flux and rad sensors and we topped off the wash reservoir.

The 7500 read: 425ppm CO2, 407mmol/m3 H2O, 28.3C, 101.2kPa, 99SS--100 after cleaning
The 7700 read: 2.0ppm CH4, 86RSSI after cleaning

We left at 13:10 PDT.
