Subject:	SGP/ECOR/E10 - Timestamp problems and intermittent data gaps
DataStreams:	sgpecorE10.00, sgp30ecorE10.b1
Description:	The raw files produced by the instrument contained bad (uncorrectable) data. Specifically the date of the data in the file is given a time that is ahead of the actual time the data was genertaed. This was caught because the date in the file was ahead of the system time of the server processing the raw file. The mentor indicated all such files were compeltely bad and unrecoverable so all files that failed to be ingested were not shipped to the archive, thus producing holes in the raw and processed datastreams. Because the problem was discovered by comparing to system time at time of processing all files between these dates should be consider suspect. Therefore the files that are on the system over these three days should be used cautiously

DataStreams:	sgp30ecorE10.b1
Description:	It was discovered that the E10 ECOR boom is aligned 17 degrees to the west of true north. Therefore, all wind direction data for the stated period is 17 degrees too high. Subtract 17 degrees from the wind direction to give the correct direction. The E10 configuration file was modified to correct this problem.

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.
