Subject:
SGP/ECOR/E16 - LI-7500 Pressure and Temperature missing
DataStreams:sgp30ecorE16.b1
Description:
The pressure and temperature measurements were not recorded; the LI-7500 serial datastream 
was not being captured by the ECOR system because of a serial port failure.

Some degradation of the latent and sensible heat fluxes may have occurred during high 
summer temperatures.  The error in the fluxes would be no more than 5 to 10% of the 
measurement, still well within the measurement error of the system.
Suggestions: 
Measurements:sgp30ecorE16.b1:
  • Latent heat of vaporization(lv)
  • Atmospheric pressure(atm_pres)
  • specific heat of moist air(cp)
  • Average temperature (IGRA internal sensor)(temp_irga)
  • latent heat flux(lv_e)
  • corrected sensible heat flux(h)
  • moist air density(rho)
