ENA/SONDE/C1 - Reprocessed and Corrected: Surface wind direction from MET incorrect by 180 
deg

DATA REPROCESSED and CORRECTED: 

The surface wind direction was incorrect by 180 degrees for three sonde launches during 
this time period when the MET instrument had been moved. Raw data for these launches have 
been corrected.

--- ORIGINAL DQR DESCRIPTION ---
---------------------------------------------------

Surface values for sonde are taken from colocated MET.  Wind direction was incorrect by 
180 deg after the wind bird was moved so that the MAWS ultrasonic could be installed.  
Three sonde launches took place with incorrect wind direction before error was corrected by 
adjusting MET wind bird to correct direction.

• Wind speed, S-to-N component, at altitude, derived from ETA model(v_wind)
• Wind speed, W-to-E component, at altitude, 915 MHz RWP(u_wind)
• Wind Direction(deg)

ENA/C1 - Reprocess: Slightly incorrect location fields

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 ;
