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/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/CO2FLX/C1 - downwelling longwave hemispheric irradiance incorrect
DataStreams:	sgp30co2flx4mmetC1.b1
Description:	Downwelling longwave radiation measurements (variable "r_down_long_hemisp") are bad due to a wiring issue. Users should not use the downwelling longwave hemispheric irradiance during this period. The downwelling shortwave and longwave radiation at CF is also available from the Broadband Radiometer Station (BRS).
Measurements:	sgp30co2flx4mmetC1.b1: downwelling longwave hemispheric irradiance t_rad corrected(r_down_long_hemisp)

Subject:	SGP/CO2FLX/C1 - Reprocess: 4m instruments height
DataStreams:	sgp30co2flx4mC1.b1
Description:	The height of the 4m instruments is 4.8 m and not 4.65 m as shown in b1 datastream
Measurements:	sgp30co2flx4mC1.b1: height of instument from tower base(zm)
