Description	DATA REPROCESSED and CORRECTED: Some of the instruments were being processed with the previous "GRW-Azores" lat/lon/alt instead of the new "ENA-Azores" lat/lon/alt. The differences were minor, but have been corrected. GRW (old) lat = 39.0911 ENA lat = 39.0916 GRW (old) lon = -28.0297 ENA lon = -28.0257 GRW (old) alt = 26 ENA alt = 30.48 The data were archived in October 2016. Please retrieve the reprocessed data for use in your analysis. ORIGINAL DQR CATEGORY: Yellow (suspect) REPROCESSED and CORRECTED DATA ARCHIVED:2016-10 REPROCESS IDENTIFICATION NUMBER: RID 1460 --------------------------------------------------- --- ORIGINAL DQR 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 ;
