Others: Qin, Iosif

Summary: Regular maintenance

Weather: sunny and very warm, no wind

 

We arrived to Riet Vell after being at la Llanada.

We filled the methane water bucket, which was around 50% full.

We cleaned the sensors. There were a lot of mosquitoes and spiderwebs. Radiometer and the camera enclosure crystal were quite gross. We also saw one duck (who was underneath the tower wooden platform) and a mouse.

We downloaded met data: the last weeks are in a file named Met30min-UAB-5CD…. The Met30min.dat one does not have the last 2 weeks of data. When we downloaded the data it was saved to Met30min (without .dat), but only the last 2 weeks. Met30min.dat is the gap filled one until 07/05. We will need to fix it later in the lab.

We entered through Angèlica’s account. We connected to internet first to sync new data.

We downloaded flux data from the usb.

We downloaded phenocam pictures.
