Subject:	SGP/EBBR/E8 - Sensible and Latent Heat Flux Suspect
DataStreams:	sgp30ebbrE8.b1, sgp15ebbrE8.b1, sgp5ebbrE8.b1
Description:	The left humidity sensor produced large spikes frequently. This resulted in incorrect measurements of vapor pressure gradient and thus calculations of sensible and latent heat flux.
Suggestions:
Measurements:	sgp5ebbrE8.b1: Top vapor pressure(vapor_pressure_top) Bottom vapor pressure(vapor_pressure_bottom) Bottom relative humidity (fractional)(rh_bottom_fraction) Top relative humidity (fractional)(rh_top_fraction) more sgp15ebbrE8.b1: Left relative humidity (mV)(rh_left_mv) more sgp30ebbrE8.b1: Top relative humidity (fractional)(rh_top_fraction) Top vapor pressure(vapor_pressure_top) Bottom vapor pressure(vapor_pressure_bottom) Surface latent heat flux(latent_heat_flux) Bowen ratio(bowen_ratio) Surface sensible heat flux(sensible_heat_flux) Bottom relative humidity (fractional)(rh_bottom_fraction) more
