FKB/RWP/M1 - Chaff released in Murg Valley

As part of the research activities associated with the COPS field campaign, the research 
center at Karlsruhe released aluminum chaff (2.5 cm in length) in the Murg Valley in order 
to study atmospheric diffusion.  It is possible that some of this chaff drifted over the 
AMF site and thus may have influenced the radar observations (as spurious echos).

FKB/MWRP/M1 - Reprocess: Updated 30-GHz calibration coefficient

On 9/17 the instrument was calibrated with liquid nitrogen. For the 30-GHz channel the 
results of calibration were not optimal and were causing a negative bias in the retrieved 
LWP.

On 10/9 the 30-GHz calibration parameters were updated with values derived from tip 
curves.

Data between 9/17 and 10/9 will be reprocessed to correct for the 30-GHz calibration.
