Getting AIRS Data

We have many AIRS datasets as well as data from other sensors on multiple platforms. The following methods are available for getting AIRS and other data products. Choose one method that suits your preference. Please contact us if you have any questions.

Getting AIRS Near-Real Time Data


Arrow alertImportant message for AIRS NRT data users

Anonymous FTP access to AIRS NRT data is no longer available. You must be registered NRT user to access the AIRS NRT data.

You can self-register to gain access to the data. 
1) Create an account on the EOSDIS wide self-registration system
Self-registration is available at
2) Respond to the verification email
3) Modify data retrieval scripts as necessary using username and passwor

NRT data products are currently available for Level-1B and Level-2, and are specially useful for users whose primary interest is the low latency for data availability. While operational data (above) are available within 3 days of observation, NRT data are usually available within 3 hours of observation. However, there is no commitment for a complete NRT data record. For example, if NRT data are delayed by more than 24 hours, they will not be processed.

Accuracy of Orbit (impacts geolocation of NRT products): Operational data production uses the rectified orbital parameters and satellite position that is accurate to better than 50 meters. NRT data production uses predicted orbital parameters, required to be accurate to 400 meters and generally accurate to 100 meters. Orbital prediction is slightly less accurate towards the end of the day UTC. Solar flares impact the accuracy of the orbit prediction.
