On September 26 at about 14:45 UTC the GPM radar was commanded to undertake an experimental Ka scanning approach. As the radar is not in normal observational mode no normal observational data is being generated from either the Ku or the Ka radar. This situation will continue until approximately 14:40 UTC on 29 September 2017 when the radar will be commanded back to its observational scanning approach.
