Major events that disrupt or affect the quality of the dataset will be listed here

Date Range Event Outcome
October 12, 2016 Made APT=0.8 (smaller) InGaAs no longer saturating
October 18, 2016 - December 14, 2016 Scroll pump failed, returned for maintenance IFS_P rising during this time. Retrievals should be unaffected.
January 13, 2017 - January 31, 2017 Tracker controller failure, then enclosure battery failure No data recorded
February 23, 2017 - May 26, 2017 Scroll pump failed IFS_P rising during this time. Retrievals should not be affected.
March 10, 2017 - March 29, 2017 Tracker controller failure No data recorded
July 28, 2017 Lab temps at 42C System in hold; no data
October 5-11, 2017 Site visit No data
October 5, 2017 - December 21, 2017 Poor IFS alignment Data unusable
December 18-21, 2017 Site visit to realign the IFS and install new scroll pump No data
January 30, 2018 - February 2, 2018 Ice blockage on tracker enclosure; couldn't open No data
February 3-12, 2018 InSb not filling No InSb data; InGaAs unaffected
March 2-8, 2018 No LN2 No InSb data; InGaAs unaffected
May 14-24, 2018 No LN2 No InSb data; InGaAs unaffected
May 28-August 17, 2018 No LN2 No InSb data; InGaAs unaffected
July 22, 2018 Implemented interspersed low resolution and high resolution scans No impact to TCCON data; added low resolution "COCCON-style" data
August 14, 2018 Chiller turned off due to cracks in heat exchanger Fewer lamp scans; normal operations unaffected
August 18, 2018 Began LN2 delivery instead of generation Hopefully more reliable source of LN2 and less OCS contamination of the lab
Dec 3, 2018-May 10, 2019 Source mirror motor unable to move smoothly due to dirt in toothed wheel in motor assembly No atmospheric data loss; no lamp scans (no ILS monitoring)
May 10-16, 2019 No light reaching detectors; misaligned source compartment No data until ~11 am CST on May 16, 2019
