Subject: | SGP/ECOR/E24 - Reprocess: Sonic analog input failure |
DataStreams: | sgp30ecorE24.b1 |
Description: | All the data based on H2O and CO2 "analog signals" (latent heat flux, CO2 flux, etc.) are incorrect for the period of 10:00 June 4, 2004 to 17:30 Sept. 16, 2004 due to to failure in sonic anemometer analog input circuitry. Correct water vapor density and CO2 concentration data are stored in IRGA (infrared gas analyzer) raw data files (sgpecorE24.00 datastream); that data may be used to re-calculate fluxes. |

DataStreams: | sgp30ecorE24.b1 |
Description: | Due to system clock instability on ECOR computers their system time is adjusted approximately once per hour; sometimes this adjustment leads to backward time jumps over midnight, into the previous day. In this case all the data based on CO2/H2O measurements might be erroneously marked as bad. Below is a list of times when that might have happen.

Description: | An inadvertant power outage caused the ECOR program to shut down abnormally. When power was restored, the timestamps on the ECOR files were 7 hours behind the correct time and the site ID was not accessed from the ECOR configuration file resulting in site ID (05) being replaced with "AN". These conditions caused the ECOR files to be unrecognizable and therefore are presently missing in the Archive. Correction of the timestamp and ID in the files should allow them to be processed and added to the Archive. |

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. |
