ENA/C1 - Reprocess: Slightly incorrect location fields
DataStreams:enaceilC1.b1
Description:
Some of the instruments are being processed with the previous "GRW-Azores" lat/lon/alt 
instead of the new "ENA-Azores" lat/lon/alt. The differences are minor, but will be 
corrected. The respective GRW and ENA lat, lon, and alt values are as follows:
 
GRW  lat = 39.0911 ;
ENA lat = 39.0916 ;
GRW  lon = -28.0297 ;
ENA  lon = -28.0257 ;
GRW  alt = 26 ;

AWR/CEIL/S1 - Reprocess: Incorrect averaging_inverval global attribute
DataStreams:awrceilS1.b1
Description:
When the ceilometer software was changed from CT-View to CL-View, several firmware 
configuration changes were made to the model CT25K for consistency with the CL31 at other sites, 
including the data acquisition interval which was changed from 15 to 16 seconds. 
However, the global attribute "averaging_interval" in the ceil datastream was not changed.
