K. Strong (U. Toronto) — Bruker 125HR (operated at 257 cm OPD, 0.004 cm-1 resolution in the mid-infrared), installed in July 2006. Direct-sun solar absorption spectra are collected in a semi-automated operation on clear-sky days from polar sunrise (approx. February 20) until polar sunset (approx. October 20). Three intercomparison campaigns with the Eureka Bomem DA8 FTIR were conducted prior to its removal in 2009: February to April 2007, July 2007, and February to April 2008. Alternating mid-infrared NDACC and near-infrared TCCON measurements have been made on a semi-daily basis since 2010. Operations in 2012 and 2013 were reduced due to funding. Operations since April 2020 have been severely affected by the lack of on-site support due to the COVID-19 pandemic, funding, and restricted access to the Ridge Lab, with NDACC MIR measurements currently limited to campaigns.
