I am currently using the AIRS Version 7 Level 2 product (AIRS...L2.RetStd_IR.v7.0.1.0) for my ongoing research, and I am particularly interested in utilizing the vertical profiles of relative humidity (RH) provided at the 15 pressure levels.

In this context, I would like to inquire whether there are any published documents (such as validation reports, technical notes, or peer-reviewed articles) that assess the performance of AIRS RH profiles. Specifically, I am interested in studies that compare AIRS-derived RH with independent observations, such as radiosonde measurements, microwave radiometers, or other in situ or remote sensing datasets, including any known biases or uncertainties.

I have come across some research articles that compare AIRS water vapor content with CMR and GRUAN observations (e.g., https://doi.org/10.1029/2018JD028930). However, I am specifically looking for similar validation or intercomparison studies focused on RH profiles.

I would greatly appreciate it if you could point me to relevant references or resources that document such comparisons.


Sincerely,

Hello,

The DOI link for this dataset (see the reference below) points to the dataset landing page. Under the "Documentation" tab on the dataset landing page there is a link to the "AIRS Documentation Page" that includes all of the science team provided documentation. There you can find a link to the "AIRS Version 7 Level 2 Performance Test and Validation Report". While that report does not use the exact same radiosonde measurements as the paper you cited it does compare the measurements with other radiosonde campaigns. You can can also find other peer reviewed articles under the "References" tab on the dataset landing page.

We hope this helps and please let us know if we can be of further assistance.
