Subject:
NIM/WACR/M1 - Reprocess: Height offset / Reflectivity Error
DataStreams:nimwacrM1.b1
Description:
There was a misunderstanding regarding which radar gate contained the 'main
bang' and as a result the heights recorded in the nimwacrM1.b1 files are too
high by 42.857 m (offset by one gate).	As a result, the IF attenuation
correction applied to Reflectivity was too low by 5 dBZ at the 3rd and 4th
gates.	Also, Reflectivity values at all gates are too high by approximately 1 to 2 dBZ 
(less above 400 m AGL) due to the height error in the reflectivity
range correction.  All affected data will be reprocessed.
Measurements:nimwacrM1.b1:
  • MMCR Reflectivity(Reflectivity)
  • Range Heights (center of radar sample volume)(heights)
