The TRMM Orbit Viewer

The Orbit Viewer is a tool for displaying the HDF data of the Tropical Rainfall Measuring Mission (TRMM). Since 1997, the TRMM Science Data and Information System (TSDIS) at NASA Goddard has developed and distributed the Orbit Viewer. If you have questions about the Orbit Viewer, contact the TSDIS Helpdesk at The Orbit Viewer runs on UNIX and Microsoft Windows.

The Orbit Viewer makes it easy to perform an initial examination of TRMM data files. The viewer allows you to display TRMM data at the full instrument resolution on a map of the tropics. Vertical cross sections and 3D images of rain structure can also be created. Instructions for using the viewer's many features are provided in the tutorial that is included in the installation as a PDF file. The tutorial can also be downloaded separately from the FTP site. With a resolution of approximately 90 dots-per-inch (dpi), the images generated by the Orbit Viewer are suitable for on-screen display or for informal presentations. The Orbit Viewer, however, is not designed to create the high-resolution images (300-600 dpi) for publication.

The Orbit Viewer for TRMM data was developed by NASA, and any use should be acknowledged. The Orbit Viewer is written in the IDL language, which is manufactured by Research Systems, Inc. (RSI).
