Arrived about 11:30. Cold, overcast, light wind from the north swinging a little west. No birds on the field though lots of swans and geese in the air.

Generator running. LGR pressure very low 47Torr. The filters seemed relatively clear, small adjustment of bypass valve brought pressure back into range.

Solar power down. I disconnected the solar panels from the charge controller and connected a 12VDC power supply to the solar inputs. Seemed to be working pulling better that 3amps to charge the batteries and power the system.

Radiometers looked clean. Cleaned dew off bottom lens of LI7500.

LGR
11:56, 2.022ppm, 9404.76ppm, 408.52ppm, 25.73C, 145.26Torr, 17.309usec, 10Hz

Copied data and swapped card.

Connected Verizon modem with new software and external antenna. And setup met and ip address to be sent to UCB once per day. Data came in this morning. We will see how robust it is.
