Things are going well in general. Still trying to get CH2O running but HONO is working well we think. Had both HONO systems running last night.Ga Tech CIMS is up and running. We have nearly all our gas phase measurements except CH2O. Aircraft are having problems with icing in McMurdo but if the weather gets better the Twin Otter should come to the pole today (Mon). The OH and HO2 are running well. The Twin Otter flew another two flights yesterday, one going north along the transAntarctic mountains the other going south in a bee-line directly to the Byrd Glacicer and the flew ~ 150 miles up the glacier at 100'. Unlike the day before, only very modest levels of NO and NOy were seen, e.g. max 60 pptv NO and 250pptv of NOy. Unlike the 400-500 NO seen over one segment of the glacier and 700 pptv NOy.. |
