Subject:
SGP/ECOR/E1 - ECOR Pressure and Temperature Missing
DataStreams:sgp30ecorE1.b1
Description:
The pressure and temperature from the CO2/H2O sensor is missing due to a failure of some 
kind.
Measurements:sgp30ecorE1.b1:
  • average temperature (IGRA internal sensor)(temp_irga)
  • average atmospheric pressure (IGRA internal sensor)(atm_pres)

Subject:
SGP/ECOR/E10 - Reprocess: Wind Direction Incorrect
DataStreams:sgp30ecorE10.b1
Description:
It was discovered that the E10 ECOR boom is aligned 17 degrees to the west of true north.  
Therefore, all wind direction data for the stated period is 17 degrees too high.  
Subtract 17 degrees from the wind direction to give the correct direction.

The E10 configuration file was modified to correct this problem.
Measurements:sgp30ecorE10.b1:
  • vector averaged wind direction(wind_dir)
