Subject:	TWP/MPL/C3 - False cloud detection at 15-20km
DataStreams:	twpmplpolC3.b1, twpmplpolavgC3.c1, twpmplpolavgC3.s1, twpmplsmask1clothC3.c1
Description:	During the period specified, clouds were sometimes incorrectly detected at 15-20km. These artifacts were seen as quasi-stationary layers that were clearly not atmospheric in origin. A replacement instrument was installed in May 2007 to correct the problem.
Measurements:	twpmplpolavgC3.s1: Preliminary cloud base height above ground level, co-pol(preliminary_cbh_co_pol) Preliminary cloud base height above ground level, cross-pol(preliminary_cbh_cross_pol) Attenuated backscatter, copol(signal_return_co_pol) Attenuated backscatter, cross pol(signal_return_cross_pol) twpmplpolavgC3.c1: Attenuated backscatter, cross pol(signal_return_cross_pol) Preliminary cloud base height above ground level, cross-pol(preliminary_cbh_cross_pol) Preliminary cloud base height above ground level, co-pol(preliminary_cbh_co_pol) Attenuated backscatter, copol(signal_return_co_pol) twpmplsmask1clothC3.c1: Heights twpmplpolC3.b1: signal_return Preliminary cloud base height above ground level(preliminary_cbh)
