Subject:
SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR 
Header
DataStreams:sgp30ebbrE12.b1
Description:
The units for Soil Heat Capacity (cs1, cs2, cs3, cs4,
cs5) in the EBBR 30 minute netcdf header have been 
incorrect from the beginning of processing the data
into netcdf files.  The correct units are MJ/m^3/C.
   
This does not affect the data quality.

(NOTE: The actual begin date of some of these data streams
 is as early as 7/4/93.  This DQR applies to all 30m EBBR
 data.)

Subject:
SGP/EBBR/E12 - Wind Direction Sensor Malfunctions
DataStreams:sgp30ebbrE12.b1
Description:
For much of the period above, a malfunction in the E12 EBBR wind direction 
sensor (insect larvae shorting out the circuit board) caused incorrect 
values for 5 minute res_ws, wind_d, and sigma_wd, 15 minute mv_wind_d, and 
30 minute res_ws, wind_d, and sigma_wd.  Wind direction normally indicated 
north (near 0 or 360 degrees); there were some times during the period when 
wind directions looked good, but the lack of variation in direction and sigma 
implies that the data is suspect.  Therefore, it would be wise to flag all
of the values listed above during the entire time period as incorrect. 
The wind direction sensor (S/N 3081) was replaced with S/N 3042 at 1515 GMT 
on June 8, 1997.

  • Wind direction vector mean(wdir_vec_mean)
  • wdir_vec_std
