Data set updates: IceBridge CReSIS Data at NSIDC DAAC

USO-NSIDC
Dear Colleague,

Radar data from the second of NASA Operation IceBridge’s two late-2017 Antarctic campaigns are now available as updates to the IceBridge MCoRDS L1B Geolocated Radar Echo Strength Profiles, Version 2 and IceBridge MCoRDS L2 Ice Thickness, Version 1 data sets at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). These data were acquired between 28 November 2017 and 18 December 2017 during surveys out of McMurdo Station using the University of Kansas Center for Remote Sensing of Ice Sheets (CReSIS) 8-element ultrawideband VHF/UHF MCoRDS onboard the NASA-contracted Airtec BT-67.
 
Along with repeat surveys of missions previously flown by the NASA P-3 in 2013 and the NASA DC-8 in multiple years, this campaign also surveyed multiple glaciers within and near the Transantarctic Mountains that had not been previously surveyed by Operation IceBridge. This new version of MCoRDS represent an improvement in bandwidth relative to previous MCoRDS datasets collected by Operation IceBridge. Typically, for repeat missions, this system operated at maximum bandwidth (150-450 MHz). For previously unsurveyed regions or regions where substantial crevassing or thicker ice was anticipated, it was operated at a reduced bandwidth (180–210 MHz), comparable to the previous generation of MCoRDS.
