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)

Subject:	SGP/TSI/C1 - Water on lens
DataStreams:	sgptsiskycoverC1.b1
Description:	After a rain episode, drops of water collected on the lens window causing the cloud fraction values to be suspect. To prevent this, a drip edge was formed around the bottom of the enclosure with thick electrical or splicing tape.
Measurements:	sgptsiskycoverC1.b1: count.sky count.opaque Cloud amount, opaque (percent)(percent.opaque) region.zenith.count.thin region.zenith.count Cloud amount, thin (percent)(percent.thin) count.thin region.zenith.count.opaque

Subject:	SGP/KASACR/C1 - Mean Doppler Velocity sign reversed
DataStreams:	sgpkasacrawrhiC1.b1, sgpkasacrblrhiC1.b1, sgpkasacrcrrhiC1.b1, sgpkasacrcwrhiC1.b1, sgpkasacrppiC1.b1, sgpkasacrrhiC1.b1, sgpkasacrslrC1.b1, sgpkasacrspeccmaskcopolC1.a0, sgpkasacrspeccmaskxpolC1.a0, sgpkasacrvptC1.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.
Measurements:	sgpkasacrcwrhiC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrslrC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrspeccmaskxpolC1.a0: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrvptC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrblrhiC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrppiC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrspeccmaskcopolC1.a0: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrcrrhiC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrawrhiC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrrhiC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity)
