Vaira
2019-04-16

I arrived at about 10:30 with Siyan and Jiangong. It was cool and overcast with a little of last nightâ€™s rain still in the air. The grass was wet with the rain but the ground seems a little less soggy. We made it to the pond without four wheel drive. The pond level was 21.83ft

We did the standard fieldwork. We replaced the desiccant inside the BF3 diffuse PAR sensor. I added a homemade screen to the tipping bucket.

The 7500 was wet when we arrived â€“ after wiping off the water the readings were good.

I forgot to bring fresh 7500s to swap for calibration.
