DataStreams:enametC1.b1
Description:
DATA REPROCESSED and CORRECTED: 

The wind sensor was not aligned correctly. Wind directions during this time are off by 180 
degrees. The raw data were modified and the data were run through the ingest to address 
the issue.

The data were Archived in July 2016. Please retrieve the reprocessed data for use in your 
analysis.

ENA/C1 - Reprocess: Slightly incorrect location fields
DataStreams:enametC1.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 ;
ENA  alt = 30.48 ;
Measurements:enametC1.b1:
  • Altitude above mean sea level(alt)
  • North latitude(lat)
