AIRS has been running for over 20 years and is a very reliable data source, so I intend to use AIRS data for scientific research over the long term. I have already registered and am looking to search for and use the LIB radiation data from AIRS, with the dataset name SUBIBRAD (e.g.,AIRS.2023.09.18.051.L1B.SUBIBRAD.v5.0.25.0.G23261111848.hdf). However, I couldn’t find this type of data in the AIRS dataset list; I only found the AIRS_Rad data (e.g., AIRIBRAD.005:AIRS.2023.09.18.018.L1B.AIRS_Rad.v5.0.25.0.G23261111206.hdf). Could you kindly provide me with the link to access the SUBIBRAD data?

Thank you very much, and I look forward to your response.

The filename "AIRS.2023.09.18.051.L1B.SUBIBRAD.v5.0.25.0.G23261111848.hdf" is just a file that has been subsetted from the following dataset:

AIRS project (2007), AIRS/Aqua L1B Infrared (IR) geolocated and calibrated radiances V005, Greenbelt, MD, USA, Goddard Earth Sciences Data and Information Services Center (GES DISC), Accessed: [Data Access Date], https://doi.org/10.5067/YZEXEVN4JGGJ

If you follow the link for "Subset/Get Data" and select "Get Original Files" rather than "Get File Subsets using the GES DISC Subsetter", you will get the original files. The subsetter changes the "AIRS_Rad" string to "SUBIBRAD" in the filename.

Since the AIRS instrument will be decommissioned in 2026 you may also want to consider using the JPSS data as well.
