The weather is finally
good enough to risk digging out the bridge and moving the Bally lab to
a new pristine area of snow |

Pull! |
Good enough! |

| It's amazing how hot you can get - even
at these temperatures! |

The camp staff are also hard
at work clearing up after the storm. Unfortunately, the snow clearing
activities were too much for a section of the group Weatherport tent.

Oops! |
Just as well Andreas wasn't sleeping! |

Cold and clear
with "modest" SE winds. Jack comments that it seemed a little bitter
on the trek out to the science area because of the headwind, but at least
it isn't strong enough for the snow to be moving much. Unfortunately, the (repaired) berthing tent was much colder last night with all that snow removed (by about 30F) - less insulation! So there are some slightly disgruntled scientists this morning... After moving the bridge, it's time to dig a pit to look at the snow structure where we have been sampling. |

| We sample the snow at different depths
to construct profiles of physical properties like porosity and chemical
properties like nitrate content. |

Here are some more glimpses

| It is another splendid afternoon, crisp
and clear. A little windier than yesterday, but so far no sign of
clouds. Dave (aka the napmeister) confirms that NO is looking pretty good, and he says, for the first time, that he may be seeing OH levels that are higher than background. |

Another beautiful morning in paradise, -45
C with 10 knots of breeze from SSE. The scientists are going to try their first shading experiment today. One of the sheets of OP2 (used for shading out the UV-light, while still allowing visible radiation to reach the experimental area) broke overnight, just a corner. It was a struggle to get ready, but seems they are just about there. |
The frame is in place ready for the
shading panel

Jeff and Manuel put the UV blocking panel in place |
| This evening Jeff and Dave have taken shovels
in hand and redone "Eddie's stairs" in a manner that might allow better
access for people and equipment (while it lasts). |

Things are much the same up at Summit this
morning: -42 C with about 12 knots from the south. High thin clouds
right now (yesterday was nearly crystal clear). They are going to try shading again, reversing the order of the cardboard and OP2 shading panels (OP2 first today). |
Another shading experiment |

Barry Lefer skidood out to the Colorado
University Automated Weather Station (AWS) to download some data and to
reprogram it so that it calculates ws, wdir, temp, press, rh, etc every
minute instead of every hour. This system is part of the Greenland
Climate Network (GC-Net) that Koni Steffen from CU runs. |
