This IPHEx AMPR Version-1 dataset was active from 28 May 2015 to 6 July 2015, and has now been retired.
The new version is now available at

The GPM Ground Validation Advanced Microwave Precipitation Radiometer (AMPR) IPHEx dataset was acquired by the AMPR instrument during the IPHEx field campaign in North Carolina from May 1, 2014 through June 14, 2014. These files included the Level 2B calibrated and georeferenced brightness temperature for the four AMPR-observed frequencies (10, 19, 37, 85 GHz). These data are archived in a netCDF-4 format that contains the calibrated brightness temperatures in addition to ER-2 aircraft navigation and instrument scene georectification variables. A set of Python software has been developed for reading, plotting, and providing some additional analysis capabilities. The AMPR instrument is managed by NASA Marshall Space Flight Center.
