Processing, archiving and distributing Earth science data
at the NASA Langley Research Center

I can't read the data I just downloaded.

For most of the data we archive, we also provide read software. If you were unable to receive the read software with your order, select the project name on the Projects Supported page. You will be taken to the appropriate project table, where you can download the read software.


If you have tried using the read software and are still experiencing problems, please have the following information ready when you contact User Services to allow us to assist you more effectively:
