Subject:
SGP/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry
DataStreams:sgpsondewnpnC1.b1
Description:
The output precision of the following variables was increased 20060928

alt  changed from 1m to 0.1m
dp   changed from 0.1degC to 0.01degC
pres changed from 0.1 hPa to 0.01 hPa
RH   changed from 1%RH to 0.01%RH
tdry changed from .1degC to 0.01degC

Note that the increase in precision does not necessarily imply an increase in accuracy.  
Users are cautioned to continue to use their best scientific judgement when using these or 
any other data.
Measurements:sgpsondewnpnC1.b1:
  • alt
  • Dry Bulb Temperature(tdry)
  • Dewpoint Temperature(dp)
  • Humidity, relative(rh)
  • Pressure, atmospheric, constant value of model level, RUC model output(pres)

SGP/WSACR/C1 - Mean Doppler Velocity sign reversed
DataStreams:sgpwsacrcrrhiC1.b1, sgpwsacrcwrhiC1.b1, sgpwsacrhsrhiC1.b1, sgpwsacrrhiC1.b1,
sgpwsacrslrC1.b1, sgpwsacrspeccmaskcopolC1.a0, sgpwsacrspeccmaskxpolC1.a0, sgpwsacrvptC1.b1
Description:
The signs of the mean_doppler_velocity field values are incorrect.  The ARM convention for 
this field is that positive velocities indicate motion away from the radar.  However, 
the velocity data in these files have their signs reversed, so that motion TOWARD the radar 
has a positive sign.
