Subject: | SGP/ECOR/E10 - Sensor failure |
DataStreams: | sgp30ecorE10.b1, sgpecorE10.00

Description: | Due to sensor failure all the parameters measured by the Infrared Gas Analyzer (water
vapor density, CO2 concentration, fluxes of latent heat and CO2, etc.) are incorrect for the
period of 18:30 Oct. 22, 2004 to 22:00 Dec. 14, 2004. The data is irrevocably lost. |

Subject: | SGP/ECOR/E10 - Reprocess: Incorrect H2O, CO2 |
DataStreams: | sgp30ecorE10.b1, sgpecorE10.00
|
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). |
