Subject: | SGP/ECOR/E3 - Failed sensors |
DataStreams: | sgpecorE3.00, sgp30ecorE3.b1 |
Description: | Data missing due to failed sonic anemometer and infrared gas analyzer. A new sonic was installed on June 16. All the data from May 25, 03:00 to June 16, 17:30 are irrevocably lost. |

Subject: | SGP/ECOR/E3 - Failed IRGA |
DataStreams: | sgp30ecorE3.b1 |
Description: | Infrared gas analyzer (IRGA) failed 6/16; a new IRGA was installed on 6/30. All data related to CO2 and water vapor concentration measurements (including CO2 flux and latent heat flux) are incorrect for the period of June 16, 2004, 17:30 to June 30, 2004, 17:30. Wind and sensible heat flux data are OK. |

Subject: | SGP/ECOR/E3 - Data transfer problem |
DataStreams: | sgpecorE3.00, sgp30ecorE3.b1 |
Description: | Serial communication with one sensor (the IRGA) were partially disrupted due to deteriorating hardware from 13:53, Dec. 19, 2004 to 09:31 Dec. 20, 2004. Serial data from the IRGA is mainly used to get sensor status codes, so this might lead to false increase of "bad" point count. It seems that IRGA analog outputs (stored in raw sonic data file, primary source of data) were not affected, so the flux data may be reprocessed or verified using raw sonic data files and ignoring IRGA sensor status. |
