Sherman
2014-12-23

I arrived about 8:52 with Kyoko and Hisashi. It was very foggy, but the fog layer was low, the top of the bridge was above the fog. The field was very wet with puddles and heavy dew. There was no wind and the fog looked like it was lifting. By afternoon on the way home Sherman was mostly fog free.

The LGR read: 9:04, 20.75C, 43.0Torr, 14.727usec, 10Hz, 2.941
I checked the external 2um filter and it was tough to blow through, but the pressure did not improve with the filter off. The internal filter or pressure controller are probably fouled. I was able to adjust the bypass valve to get pressure to 149Torr. The CH4 was then 2.632 though I'm not sure that was due to the change in pressure.

The 7500 read: 25.11mmol/m3 CO2, -102mmol/m3 H2O,102.6kPa, 11.6C, 255diag
The 7500 and sonic were draped in dew covered spider webs. I cleaned them off, but didn't write down the readings afterwards.

I collected the camera photos and cleaned the window - might try putting Rain-X on the windows.

The tipping bucket was full of water up to the screen. I let it run through the bucket.

The HMP45 fan is dead - need better all-weather fans
