HFE/WACR/M1 - Reprocess: Reflectivity and Height Offsets
DataStreams:hfewacrM1.b1, hfewacrspeccmaskxpolM1.a0, hfewacrspeccmaskcopolM1.a0
Description:
The instrument vendor has informed us of a range (height) offset of 13 m and has provided 
an updated reflectivity calibration. All values reported for 'Reflectivity' are 
approximately 3 dB too low. In addition, the Reflectivity in the first and fourth range gates 
(starting from the surface) need to be further corrected by an additional 2.7 and -0.9 dB, 
respectively. The 'height' field values are 13.33 m too low.  The data will be reprocessed 
to correct these problems.

PYE/AOS/M1 - Data processing problem
DataStreams:pyeaosM1.a1, pyenoaaaosM1.b1, pyenoaaaosavgM1.b1
Description:
The AOS data was reprocessed for the AMF, SGP and NSA sites. There was an error in the 
processing of the corrections for the PSAP absorption signal such that a low pass filter was 
implemented for the scattering data used in these corrections.The difference between the 
corrected and previous data is < 0.05 Mm-1 (below the instrument detection limit) and 
should not have a significant effect on the previous data. Data will be reprocessed at a 
later time when more significant changes to the data processing are implemented.
