Subject:
SGP/ECOR/E24 - Water Vapor Density Incorrect
DataStreams:sgp30ecorE24.b1
Description:
Mean Water Vapor Density (mean_q) often did not trend well with the co-located SMOS and 
sometimes jumped downwards approximately 200 to 300 mmol/m^3.  Some of the instances were 
clearly a result of contamination by precipitation, but others were not; the latent heat 
flux was sometimes affected.

It was determined that all instances of this behavior from the beginning of 2008 through 
the beginning date of this DQR were caused by precipitation/dew/frost.
Measurements:sgp30ecorE24.b1:
  • Latent heat flux(lv_e)
  • Mean H2O density(mean_q)
