Summary: Fixed and installed soil moisture sensors, soil samples, checked flux system.
| Visited Vaira. ~1500. 1. Hot and dry. Surface temp near 50C. Albedo on Par about 25%, low net radiation. 2. Lots of grasshoppers in the area and hanging around LI-7500. If we get spikes in data they may be due to grass hoppers. 3. Fixed the soil moistsure sensors, ch 2 and 5. The number 5 ch was open and blank. Installed sensor number 7 and buried it at about 23 cm. The soil was very hard and could not go deeper. To the touch the soil felt moist. Took a few grab samples of soil at about 10 to 20 cm for a general gravimetric reading. 4. Soil moisture sensor on the Ch 2 was #16. The cord had been chewed some. We installed sensor number #11. This sensor is installed in the surface layer. Readings of soil moisture sensors at 1600 are: Ch 1: 0.218 Ch 2: 0.107 Ch 3: 0.215 Ch 4: 0.272 Ch 5: 0.271 5. Gravimetric samples are in oven Sample 1, empty, 108.13, wet and container, 262.03 Sample 2, empty, 109.29, wet and container, 325.59 6. Flux system was operating ok. 7. Battery on cow fence is low. |
