Summary: Swapped solar shield and fan from HMP45.

2012-02-15

I arrived about 12:00PST noon. It was clear, sunny and super windy. The fields continue to drain. There are still some puddles here and there. There were lots of birds in the test fields to the south.

I collected data. The LGR read:
11:51PST, 30.58C, 137.61Torr, 13.930usec, 10Hz, 1.875ppm

I adjusted the bypass valve to bring pressure up to 146.0Torr.

I swapped the solar shield and fan on the HMP45. I also swapped its Teflon cap.

The LI7700 RSSI was about 50. I did not clean the mirrors.

The CR1000 is still only getting the LGR data at about 5Hz
