Hurricane Arthur battered North Carolina after coming ashore late last night at 0315 UTC (11:15 PM EDT). The TRMM satellite flew directly over Arthur on July 3, 2014 at 1922 UTC ( 3:22 PM EDT) as the hurricane was becoming increasingly more powerful. An analysis of rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments was overlaid on a 1926Z GOES-EAST Visible/Infrared image. Intense bands of thunderstorms north of Arthur's well defined eye were revealed by TRMM to be dropping rainfall at a rate of over 98.4 mm ( about 3.9 inches) per hour. One of the TRMM

Tropical storm Arthur intensified and was upgraded to a hurricane by the National Hurricane Center (NHC) early this morning. The TRMM satellite flew above the intensifying tropical storm on July 2, 2014 at 2156 UTC (7:56 PM EDT). At that time TRMM found that Arthur hadn't formed an eye but had heavy rain near the center of a well defined circulation. Rainfall derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) is shown overlaid on a GOES-EAST Visible/Infrared image collected at the same time as the TRMM pass.

The TRMM satellite had a good daylight look at tropical storm Arthur on July 1, 2014 at 1620 UTC (12:20 PM EDT) less than two hours after it was upgraded from a tropical depression. Rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data are shown overlaid on a GOES-EAST infrared/visible image collected at 1626 UTC (12:26 PM EDT). The location of very heavy rainfall around Arthur's center was shown using TMI data. TRMM PR data sliced through the southern half of the tropical storm. A 3-D view (from the west) using those data is shown above. Radar reflectivity values

A tropical disturbance east of Florida's coast became better organized and was upgraded to a tropical depression by the National Hurricane Center (NHC) on June 30, 2014 at 11:00 PM EDT (July 1, 2014 at 0300 UTC). On July 1, 2014 at 1100 AM EDT (15:00 UTC) the NHC upgraded tropical depression one to tropical storm Arthur. The TRMM satellite had an excellent view of the forming tropical depression (TD01) on June 30, 2014 at 1717 UTC (1:17 PM EDT). Intense thunderstorms were shown by TRMM to be wrapping around the southern side of the low pressure center. TRMM's Precipitation Radar (PR) revealed

The GPM Core Observatory satellite was successfully launched on February 27th, 2014. Data from the GPM Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR) have the following release schedule. All data are freely available through the NASA's Precipitation Processing System at http://pps.gsfc.nasa.gov June 16th – GMI Level 1 Brightness Temperature data have been released. This includes GMI instrument swath data. July 14th – GMI Level 2 Precipitation Rate data will be released. This includes precipitation rates estimated using the Goddard Profiling algorithm (GPROF14) and are
