Subject:
SGP/ECOR/E10 - Incorrect H2O, CO2
DataStreams:sgpecorE10.00, sgp30ecorE10.b1
Description:
Due to failure of analog output circuitry in the Infrared Gas Analyzer (IRGA), CO2 and 
water vapor parameters measured by the IRGA (water vapor density, CO2 concentration, fluxes 
of latent heat and CO2) were incorrectly recorded in sonic raw data files for the period 
of 22:30 Dec. 14, 2004 to 22:00 Jan. 11, 2005. The data could be recovered from IRGA raw 
serial files (00 level).
Suggestions: 
The flux data could be recovered if raw data (sonic and IRGA) were reprocessed with 

current ECOR processing program (named "flux", version 1.9 or later) in a special mode 
using "noanalog" key (see README file in the ECOR software package). This special mode 
retrieves H2O/CO2 data from IRGA serial file rather then from analog signals in sonic raw 
data file.
