Big solar storm hitting Earth (so CNN says)

September, 2014 coronal mass ejection

SESDA 3 staff braced for the possible next “big” one – a significant X-class flare erupted on September 10, 2014 and produced two Coronal Mass Ejections (CME’s) directed towards Earth. By combining real-time imagery from three spacecraft – SOHO, STEREO, and SDO, staff helped provide accurate space weather forecasts of the speed and intensity of the powerful storms as they impacted Earth’s magnetosphere. Fortunately, the storms did not knock out the power grid and instead generated beautiful aurora at high latitudes.

GES DISC Data Products Show Record Rain in the Florida Panhandle

August 4, 2014

Between April 29 and May 1, 2014, a powerful cold front triggered storms that dropped 10-20 inches of rain over the Florida Panhandle near the city of Pensacola. Areas around the city received almost 24 inches of rain from the intense storms, and the official rain gauge at Pensacola’s airport measured an astonishing 5.68 inches in a single hour before it failed.

The GES DISC used Giovanni-4 to visualize near-real-time data from the Tropical Rainfall Measuring Mission (TRMM) to illustrate this historic rainfall event. The image below shows the total rainfall (in mm) measured by the TRMM Multi-satellite Precipitation Analysis – Real Time (TMPA-RT) instrument between April 29 and May 1. The area with the highest amount of rain (indicated in red and pink) is located between Mobile Bay and Pensacola Bay.

TRMM data are currently available from the GES DISC via the Mirador search engine, and can easily be analyzed using Giovanni-4. The GES DISC shortly will initiate distribution of data products from the recently launched Global Precipitation Measurement (GPM) mission.
