Oxford MIPAS meeting#76
7 Jun 05
As you probably know we are analyzing the NO2 in the different polar winters
that MIPAS have measured. I have plotted a time series of the NO2 data you
recently sent me for the antarctic hemisphere ([see fig. attached). I am
suspicious about the high NO2 values that we retrieved at 20-3 mb from 2 Jun
until 1st august. NO2 reach values as high as 60 ppmb at 6-7 mb ~4 July, which
we find difficult to explain from an atmospheric point of view. Could it be a
propagation error from the very high values at ~0.1mb together with the very
cold temperatures at ~10mb pressure levels? Could you or perhaps somebody at
Florence have a look at the chi2 values for this period?
Subject: Decontamination statusDear all,
Roberta and Gaetan have performed the first gain calibration since the decontamination.
The radiance reaching the detectors is 200% of that prior to the decontamination, showing that a large amount of contaminant has sublimated. As for previous decontaminations, the radiance levels are now identical to that at beginning of mission, so the Teresina campaign will benefit from optimal throughput.
We will continue to carefully monitor the growth rate of the contamination. My thanks to all involved for the accurate duration calculations, and the punctual execution.
