N2 - We present an ice-penetrating radar data set acquired over the Greenland ice sheet by aircraft during the years 1971, 1972, 1974, 1978, and 1979. The data set comprises over 177,000 km of flight lines and contains a wealth of information on the state of the Greenland ice sheet including information on ice thickness and englacial properties. During data collection in the 1970s, the data were recorded on optical film rolls and in this manuscript, we document the digitization of these film rolls and their associated geographical information. Our digitization of the data enables interaction with and analysis of the data and facilitates comparison with modern-day radar observations. The complete data set in full resolution is available at the Stanford Digital Repository (https://doi.org/10.25740/wm135gp2721) with the associated technical reports (Karlsson et al., 2023). Part of the data set has been quality checked and is available as low-resolution JPG files at The Technical University of Denmark’s data repository, DTU Data, with associated geographical information (DOI pending). Here, we release the full data sets to enable the larger community to access and interact with the data.
