UPDATE!!! Hurricane Data Analysis Tool

The Hurricane Analysis Tool allows users to overlay various data products relevant in the study of hurricanes in an area plot, a time plot or animation using an interactive tool. The data products being offered include NCEP/CPC 4-km Global (60 deg N - 60 deg S) Merged IR Brightness Temperature Dataset, TRMM's product 3B42, TMI's sea surface temperature, NCEP Reanalysis sea level pressure and QuikScat's wind. This tool is beneficial for users to obtain a visualization comparison of two products during a hurricane event.

The Hurricane Archive Gallery gets a Face Lift

Hurricane Archive Gallery gets a face lift and is now dynamic! Check out the new gallery interface that allows you to select the year and hurricanes you want to view. Data access has also been added to the gallery along with QuikScat Wind and new CloudSat images! Take a look!

Latest Generated 3-Hour Rainfall Total Images

These are the latest images derived from the 3-hour near-real-time rainfall total (TMPA or 3B42RT) of the Atlantic and Gulf regions. The images created using the Giovanni analysis tool with the latest available data granules. These are generated and updated on a daily basis to observe current rainfall total activity. You can view more current images and animations of these and other parameters, such as AIRS temperature and Surface Pressure, by visiting the Image Gallery. A Past Hurricane Archive is also available to view animations of data set parameters of hurricanes that developed over the Atlantic region.
