The science team has replanted
the group sampling probe and are making real measurements- yea! (Even though weather conditions still look less than ideal!) |
Jack sampling from his mist chamber sampler housed in the box. The sampler inlet is drawing air from the group sampling probe which is planted in the snow and pulling air from the snow pore spaces below the snow surface. |
Jack sampling from a second
identical mist chamber sampler. The inlet for this sampler is
drawing air directly from the atmosphere above the snow.

Happy Birthday Meg! Clear and cold. The temp decreased to about -43C as the winds decreased. The science team is hard at work in the Bally Building lab out at the science camp. |
Andreas (front left) with the IC Irvine whole a air sampling cans. Manuel (U Az) is behind with his formaldehyde instrument. Jeff (right) tends to the Georgia Tech NO and OH instruments. |
Andreas, Manual and Jeff say Hello. |

It's still windy
enough that Jack's mist chamber (which relies on spraying a mist of water
to trap soluble gases) on the bridge keeps freezing up. So he
has rigged a wind break that the box (and he) can hid behind! |

| After dinner Jack, Barry, Cort
and Eddie take part in another "webinar" tele/web conference to meet the
teacher, Nikki, who will be joining them at Summit for the last couple of
weeks of the experiment as part of the TREC program. Nice to meet
you Nikki! We will be sure to order some warmer weather in time
for your arrival! |

Cold and clear this morning, -47C.
Not too much wind - about 15 knots. So it's a good day for doing work that requires being out in more exposed spots - like on top of the movable Bally lab. (the lab is on skis, though these are mostly buried in the snow drifts) |

| Question: What does the napmeister (Dave Tanner) do when he's not napping? Answer: See photos |
Dave works on the CIMS instrument to measure OH that is set up in the Bally lab |
CIMS stands for: Chemical Ionization Mass Spectrometer |

The wind is up again to about 22 knots
or more, which means snow is being blown in the air and the drifts are
moving again. The list of minor irritations that the team has to deal with under these conditions mainly all share snow getting into places one would rather it not (stair well, door jamb, pockets, etc.). There will (or at least should) be a lot of stair shoveling keeping folks from getting too bored. |
Even Jack's windbreak if feeling the strain of the wind. |
The bridge is almost completely
buried and will have to be dug out and moved as soon as the wind drops
|
| Right now the door latch to the main
lab is freezing up about every 5 minutes. Sometimes you get trapped
in, other times the door will not catch, so the vestibule is also filling
up with snow. Anyway, they can say that each and every data point will have been earned! |

| It is also an adventure every time someone
heads to the Big House, as the drifts along the path keep changing . But Saturday night is Pizza Night! - A just reward for those who make the trek back to the Big House for dinner. |

weather in the traditional array of Saturday night pizzas

The wind is still blowing hard so the
team will wait to dig out and move the bridge...........waiting is often
the hardest part! |
Meanwhile, Kelly still goes out to collect surface snow samples |
Cort and Eddie catch up on sample analysis in the main lab |
| Sunday afternoon - finally the wind drops
enough that the snow is staying close to the ground, rather than in the
air - so visibility is MUCH improved! On with the science! |
Cort (left) plants his radical traps at different depths in the snow. They are used to measure how much OH radical is around down there. Eddie (right) keeps a record of which trap is being put where. |
Barry plants fiber optic cables at different depth into the snow to see how much solar radiation is making it down there - and how much radiation is needed to form the radicals that Cort and Eddie's experiment is measuring |
