Subject:	SGP/MET/E7 - T/RH values incorrect
DataStreams:	sgpmetE7.b1
Description:	The temperature, RH, and vapor pressure data were incorrect due to a loose connection.
Measurements:	sgpmetE7.b1: vapor_pressure_mean Temperature mean(temp_mean) Humidity, relative, at 2-m height, 1-min avg(rh_mean)

Subject:	SGP/MET/E9 - False tips in high winds
DataStreams:	sgpmetE9.b1
Description:	The TBRG's were mounted at a height that made them prone to vibrations caused by high winds which may have caused false tips. The end date of this DQR indicates when the rain gauge was lowered to mitigate these effects. Effects on the total precipitation amounts are assumed to be negligible.
Measurements:	sgpmetE9.b1: Corrected total precipitation measured by TBRG(tbrg_precip_total_corr) tbrg_precip_total

Subject:	SGP/ARMBESTNS/X1 - Reprocessed and Corrected: Will change ECOR input to QCECOR
DataStreams:	sgparmbestnsX1.c1
Description:	DATA REPROCESSED and CORRECTED: The ARMBESTNS data was reprocessed with improved sensible and latent heat flux values. Input data from the ECOR instrument was replaced by the QCECOR Value-added product which applies more stringent automated quality checks on the eddy correlation data. The reprocessing task will also provide the following variable name changes: latent_heat_flux_ecor will become latent_heat_flux_qcecor sensible_heat_flux_ecor will become sensible_heat_flux_qcecor lat_ecor will become lat_qcecor lon_ecor will become lon_qcecor alt_ecor will become alt_qcecor stn_ecor will become stn_qcecor ORIGINAL DQR CATEGORY: Transparent (Does not affect quality) REPROCESSED and CORRECTED DATA ARCHIVED:2016-07 REPROCESS IDENTIFICATION NUMBER: RID 1442 --------------------------------------------------- --- ORIGINAL DQR DESCRIPTION --- --------------------------------------------------- Data quality may be improved slightly after reprocessing for some sensible and latent heat flux values as input data from the ECOR instrument will be replaced with data from from the QCECOR Value-added product. The QCECOR VAP applies more stringent automated quality checks on the eddy correlation data. The reprocessing task will also provide the following variable name changes: latent_heat_flux_ecor will become latent_heat_flux_qcecor sensible_heat_flux_ecor will become sensible_heat_flux_qcecor lat_ecor will become lat_qcecor lon_ecor will become lon_qcecor alt_ecor will become alt_qcecor stn_ecor will become stn_qcecor
Measurements:	sgparmbestnsX1.c1: ECOR surface sensible heat flux(sensible_heat_flux_ecor) ECOR surface latent heat flux(latent_heat_flux_ecor)

Subject:	SGP/ARMBESTNS/X1 - Reprocess: OKM and KSU Mesonet Data Error
DataStreams:	sgparmbestnsX1.c1
Description:	The VAP code is not correctly handling the situation when the number of sites changes within a month for the OKM and KAM data. Use the OKM and KAM data with caution.
Measurements:	sgparmbestnsX1.c1: KAM air temperature(temp_kam) OKM u wind component(u_wind_okm) OKM air temperature(temp_okm) OKM surface pressure(pressure_okm) KAM v wind component(v_wind_kam) OKM relative humidity(rh_okm) KAM relative humidity(rh_kam) KAM precipitation rate(precip_rate_kam) OKM v wind component(v_wind_okm) KAM u wind component(u_wind_kam) OKM precipitation rate(precip_rate_okm)
