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.

Dusting Off GES DISC Data

June 26, 2014

A massive dust storm covered much of China this past April, turning the air brown and creating health hazards. Much of the data about this monster storm were provided by SESDA 3 scientists and engineers working at the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC), who support numerous missions that provide a wide range of critical global climate data.
For example, a number of near-real-time (NRT) data products from the Atmospheric Infrared Sounder (AIRS) instrument on the Aqua satellite provide information about the onset of dust storms. The “AIRS Dust Score” is one of these AIRS NRT products. The AIRS Dust Score numerical scale is a qualitative representation of the presence of dust in the atmosphere, and an indication of where large dust storms may form and the areas that may be affected. The Dust Score and other AIRS NRT products are fed to the NASA Earth Observing System Data and Information System (EOSDIS) Land Atmosphere Near real-time Capability for EOS (LANCE). These NRT products can be visualized using the GES DISC AIRS NRT Data MapViewer and can be overlain with data products from other instruments and satellites in Worldview, an EOSDIS tool that allows users to interactively browse global, full-resolution satellite imagery and then download the underlying data.
