TRMM Has Second Look At Typhoon Krosa
On November 1, 2013 at 1320 UTC the TRMM satellite had the second look at typhoon KROSA. KROSA weakened slightly when it passed over the northern Philippines but had started to intensify with this second pass over the South China Sea. The image on the left shows rainfall data collected by TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments overlaid on an enhanced infrared image. TRMM PR data revealed that rain was falling at a rate of over 116mm/hr (4.5 inches) in KROSA's eye wall. Radar reflectivity values greater than 50dBZ were found in the same area. The 3-D perspective

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.
