Subject: | NSA/MWR/C1 - Possible loss of accuracy due to missing blower |
DataStreams: | nsamwrlosC1.b1, nsamwrtipC1.a1
|
Description: | On 7/09 the MWR blower failed. The blower prevents snow and liquid drop from accumulating
on the window. Accumulation of snow or liquid results in a loss of accuracy of the
instrument. The loss of accuracy has consequencies on the retrieved liquid water path and
precipitable water vapor. Usually there will be an overestimation of liquid and vapor. The
blower was repaired and reinstalled on 7/20. Between 7/9 and 7/20 the tkair variable is
unavailable as well. |
Suggestions: | If the user notices unusual values between 7/9 and 7/20, he/she could compare the
data with those from the MWRP (12-channel profiler). The profiler has also a sensor to
measure air temperature. Therefore, data users who are interested in the tkair variable can
also use measurements from the profiler. |
