July 16, 2019 – GPM IMERG Animation of Rainfall Accumulations from Hurricane Barry
This 6-day animation shows the heavy precipitation that Hurricane Barry (2019) producing from July 11 to 16 in the Gulf of Mexico and the South Central U.S. While forecasters were initially concerned that the largest accumulations would extend far over land, this animation shows that the largest accumulations remained mostly off shore. The precipitation estimates shown in this animation come from a near-realtime merging and calibration of observations made by the satellites of many nations. The IMERG algorithm, run at NASA Goddard, performs this data merging. The left side of the movie shows the total accumulation starting in the early hours of July 11, 2019, while the right side shows the accumulation during just the most recent 3-hour period.
