Supertyphoon Pongsona struck the U.S. Island of Guam on Sunday, December 8, 2002. The composite image (left) of the supertyphoon was made by overlaying data from the infrared, microwave, and visible/near-infrared sensors that make up the AIRS sounding system. This storm can also be seen with the standard AIRS Vis/NIR (right).


Welcome to the JPL Tropical Cyclone Information System

The JPL Tropical Cyclone Information System (TCIS) was developed to support hurricane research. It has two components: a 12-year global archive of multi-satellite hurricane observations and, what was a near real-time portal, that supported the 2010 NASA Genesis and Rapid Intensification Processes (GRIP) hurricane field campaign. Together, data and visualizations from the near-real time system and data archive can be used to study hurricane process, validate and improve models, and assist in developing new algorithms and data assimilation techniques. Below you will find links to various portals where you can view different types of data.


Tropical Cyclone Data Archive

The TCIS Data Archive is a comprehensive tropical cyclone database of multi-parameter satellite observations pertaining to the thermodynamic and microphysical structure of the storms, the air-sea interaction processes and the larger-scale environment. Currently, it contains satellite depictions of hurricanes over the globe from 1999-2010. Users are able to browse through hurricane seasons and ocean basins to find specific storms of interest. The portal is designed to facilitate the finding of coincident observations from multiple instruments, and it provides fast access to pre-subsetted data and plots, making this a unique tool for hurricane research. Additionally, data files can be directly accessed through our .


HS3 Data Portal

This near real-time interactive portal was developed to support the multi-year Hurricane and Severe Storm Sentinel (HS3) aircraft campaign. HS3 is a five year mission with a three year airborne component (2012-2014). The campaign's main goal is to investigate the processes that underlie hurricane formation and intensity change in the Atlantic Ocean basin. This portal allows users to analyze and compare observation data and model forecasts in the North Atlantic basin from July to November of each year of the campaign.


GRIP Data Portal

This interactive web portal was developed to facilitate the 2010 NASA Genesis and Rapid Intensification Processes (GRIP) field campaign, and was run in a near real-time (NRT) during the 2010 Atlantic hurricane season. The portal integrates model forecasts with satellite observations from a variety of instruments and platforms, along with select data products from airborne instruments that participated in the campaign. Users can interrogate a large number of atmospheric and ocean parameters that were available in near real-time during the campaign to better understand the processes associated with hurricane genesis, track and intensity changes. The GRIP Data Portal is also availalbe in a .
