Summary: Installed FLIR A325sc thermal camera, check phenocams


I arrived at about 10:30 with Ana and Miriam Johnston. It was clear, sunny and warm. The grasses are about dead and the flowers are beginning to fade. Miriam is here from Harvard to set up a thermal camera and that is the main task for today.

Ana found a small garter snake in the outhouse toilet. I was able to fish it out with a stick.

While Ana and Miriam looked around for a good spot to set up the thermal camera, I started to look at getting the Latte Panda running in the Tower computer box. I pulled out the Quatech 8-port serial box and some of the old cables. Power is still difficult. However Ana and Miriam got interested in a location near the Floor tower so I went over there to look at setting up a Latte Panda there.

They decided on a location near the Floor Well looking north at a pine and some oaks. I pulled the old computer out of the Floor computer box and ran a power line and Ethernet line to the camera location. I installed the Latte Panda but could not get the old screen to work. The portable USB-powered screen worked and I was able to set up the Panda to collect images every 10 minutes.

We also set up a black panel (painted plywood) on a post in the camera’s view and positioned an Apogee IRT sn 7385 in front of it recording to a CR10X sn 47772.

The camera is a FLIR A325sc sn 48013741. It uses an uncooled microbolometer detector and has a 320x240 image with a 2C accuracy. It is using a 10mm lens with a 45 degree field of view. Its sensitivity is 7.5 - 13.0 um with a Noise Equivalent Temperature Difference (NETD - kind of like contrast) of <50mK.

I was supposed to add DI water to the batteries but I forgot to bring it with me.

The Tower Phenocam had stopped collecting images again. I moved the 126 images off the card and reinserted the card. New cards are supposed to arrive next Monday.
