NASA's D3R radar at Wallops Flight Facility. Shown, NASA engineer Manuel Vega NASA's Dual-frequency, Dual-polarization, Doppler Radar (D3R) was transferred from Goddard Space Flight Center to Wallops Flight Facility this week. D3R's dual frequencies match those of the GPM Dual-Frequency Precipitation Radar ( DPR). Some work to the D3R computing infrastructure will be performed at Wallops, and then the radar will be collocated with NASA's NPOL radar in Newark, MD.

There has been some recent convective activity within tropical storm Raymond but southwesterly wind shear and cooler ocean temperatures are predicted by the National Hurricane Center (NHC) to weaken the tropical storm to a remnant low on Wednesday October 30, 2013. Raymond contained rainfall only in an area northwest of it's center of circulation when the TRMM satellite passed above on October 28, 2013 at 2337 UTC (4:37 PM PDT). Rainfall data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) are shown overlaid on a combination visible and infrared image from TRMM's Visible and
