Description: | The SGP.C1 AERI system clock was not being regularly checked and synched with a time server between May 2001 and November 2001. When the problem was identified and the clock was corrected, a time offset of 17 minutes and 2 seconds (slow) was present. The data available from the ARM Archive have been time corrected by Dave Turner using a piece-wise linear function based on a comparison of pressure data from the AERI and SMOS. Dave indicates "this results in a good fit to the data" and "errors in the reported sample times are reduced to approximately 1 minute or less. Given the nominal three minute averaging period of the AERI, this should suffice for most applications." Data between 20011019.1615-20011029.1621 did not need to be corrected due to a series of events that caused the clock to be temporarily synched and then revert back to the linear drift pattern. Note, there are three other variables in the AERI data products which report time: Time, timeHHMMSS and rawTimeHHMMSS. The data in these variables were not modified, so these data will not agree with basetime + time_offset. Also note, VAPs which use the AERI data as input were NOT reprocessed. VAP data during the time period specified are questionable and should be used with caution. |
