Subject:	SGP/ECOR/E14 - Flux Measurements Incorrect
DataStreams:	sgp30ecorE14.b1
Description:	The ECOR datastream was corrupted; this happens when the ECOR program produces a datastream of the wrong length (i.e., leaves one or more measurements out). Fluxes and some other measurements are incorrect. Reprocessing will not correct this problem; the raw data are corrupted.
Measurements:	sgp30ecorE14.b1: Water vapor density (q)(mean_q) h(h) average atmospheric pressure (IGRA internal sensor)(atm_pres) mean co2 concentration (c)(mean_c) average temperature (IGRA internal sensor)(temp_irga) CO2 flux(fc) latent heat flux(lv_e)

Subject:	SGP/SONDE/C1 - Mixed use of RS92-SGP and RS92-KL radiosondes
DataStreams:	sgpsondewnpnC1.b1
Description:	Because of a manufacturer's production problem, we will be using both RS92-SGP (GPS windfinding and RS92-KL (Loran windfinding) radiosondes at the SGP/CF starting February 10, 2006. The radiosonde type used for the each sounding may be determined by looking the metadata variable "launch_status" in the netCDF data files.
Measurements:	sgpsondewnpnC1.b1: Wind Status(wstat) lon(lon) Mean Wind Speed(wspd) Wind Direction(deg) V-component(v_wind) lat(lat) U-component(u_wind)

Subject:	SGP/EBBR/E13 - Left Air Temperature Incorrect - Fluxes Affected
DataStreams:	sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
Description:	The left air temperature was incorrect, thus the Bowen ratio and sensible and latent heat fluxes were incorrect also.
Measurements:	sgp15ebbrE13.b1: temp_air_left sgp5ebbrE13.b1: temp_air_top temp_air_bottom sgp30ebbrE13.b1: sensible_heat_flux temp_air_bottom bowen_ratio temp_air_top latent_heat_flux

Subject:	SGP/EBBR/E13 - Fluxes Incorrect, AEM Problems
DataStreams:	sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
Description:	The AEM did not function properly, thus sensible and latent heat fluxes were incorrect.
Measurements:	sgp15ebbrE13.b1: temp_air_right temp_air_left sgp5ebbrE13.b1: temp_air_top rh_bottom_fraction temp_air_bottom temp_trh_bottom rh_top_fraction vapor_pressure_top temp_trh_top vapor_pressure_bottom sgp30ebbrE13.b1: sensible_heat_flux bowen_ratio temp_trh_top rh_bottom_fraction vapor_pressure_top latent_heat_flux vapor_pressure_bottom temp_air_bottom temp_trh_bottom rh_top_fraction temp_air_top

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: Dummy altitude for Zeb(alt) Dry bulb temperature(tdry) Surface dew point temperature(dp) Relative humidity inside the instrument enclosure(rh) Retrieved pressure profile(pres)
