10-14-2010 I arrived about 8:30PST with Dennis and Jaclyn. It was warm and sunny with scattered high clouds; little to no wind from the northeast. The grass and rice was wet with dew from overnight. The fields to the west are being harvested. A new access road is being built at the northeast corner of field one over the drainage ditch that runs along the east of the field. The computer was sleeping probably due to a power outage. I restarted the computer. The LGR was running okay but pressure was a little low. High CH4 reading: 8:33PST, 26.31C, 127.69Torr, 16.103usec, 10Hz, 3.261ppm I adjusted the bypass valve to bring pressure back up to 144Torr. Ch4 concentration didn’t seem to change much. When we left the CH4 was down to 2.696ppm. The air conditioner seemed to me running too much. It is set to come one when the box is 80F, but it seemed to be cooling even though its panel said 67F in fan only mode. The clean filter light was on but the filter never seems to be very dirty. I pushed the clean filter button and the light went out. I think it maybe time controlled. Several power outages cause the computer not to collect much CR1000 data and the CR23x data was not properly split into daily files. I copied the data and swapped the card in the CR1000. We went to the original tower location to retrieve the solar panels and charge controller. Some canine had decided the wooden base under the solar panels was a good place to poop. We dismounted the panels and removed the hardware from the wooden base. We also removed the stakes holding the base to the ground and flipped over the base for later. We got keys for the Mayberry site from the Twitchell trailer. |
