Group: Quality

   The high altitude data are generally lower quality than the low altitude data. 
   This is because: 1. The cross-track antenna resolution is proportional to 
   range creating severe layover problems in mountainous terrain. 2. The 
   sidelobes from the 30 microsecond pulse duration mask out some of the returns 
   that otherwise would have had a high enough signal to noise ratio. 3. The 
   range to target is greater so the spherical spreading power loss is greater 
   leading to a lower signal to noise ratio.

Group: Summary

   This data set contains radar echograms taken from the Center for Remote 
   Sensing of Ice Sheets (CReSIS) ultra Multichannel Coherent Radar Depth Sounder 
   (MCoRDS) over land and sea ice in the Arctic and Antarctic. The data were 
   collected as part of Operation IceBridge funded aircraft survey campaigns.
