Summary: Regular data collection/cleaning, installed new water level sensor, loose wire inside met box causing power issues--needs more work
| 2023-08-08 West Pond Robert and I arrived at 13:20 PDT. The inlet was on. It was hot and sunny. There were goats on the interior levee road and many of the lower willow leaves have been grazed. Robert was shocked with how fast the willows had grown since they were trimmed two months ago. He trimmed some of the tallest branches back. The staff gauge read 59cm. I installed a new Campbell water level sensor sn 20010026. It was the same SDI-12 address as the old sensor (addr=0), so conveniently I didn’t need to change the program. The new sensor is hanging by the staff gauge. Eventually I would like to put it in a well, but for now at least we are getting continuous water level data. Robert cleaned flux and rad sensors and reported there were lots of bird feathers and spiderwebs around the radiometers and that the sensors were generally dirty. I topped off the wash reservoir. I downloaded met, cam, and USB GHG data. There is still some power issue in the box with the 12V power strip because the datalogger shuts down and the HMP fan stops spinning whenever I’m jostling wires inside the met box. The data in the past 2 weeks seems complete, although the CR1000 voltage varies between 11.4 and 11.9V. Maybe another DC-DC converter with longer/thicker wires for better contact in the screw terminal. The 7500 read: 412ppm CO2, 726mmol/m3 H2O, 27.8C, 101.3kPa, 99SS--100 after cleaning The 7700 read: 1.98ppm CH4, 47RSSI—80+ after cleaning We left at 13:57 PDT. I updated SMAP for WP WaterLevel. I was able to use the staff gauge data. Conveniently the staff gauge read 59cm on both 2023-07-11 with the old sensor and on 2023-08-08 when I installed the new sensor.The sensor is about 40cm higher than before, about 12cm above the bottom of the staff gauge. |
