What is it about?
Humidity profiles are retrieved from a surface-based microwave radiometer over the equatorial Indian Ocean. Retrievals are evaluated against radiosonde profiles as part of the DYNAMO campaign. Application of the bias corrected humidity profiles and challenges in retrieving moisture profiles in a tropical environment are discussed.

Why is it important?
The interaction between equatorial convection and humidity as a function of height, at a range of time scales, remain an important research frontier. Our findings suggest that microwave radiometers can usefully augment more expensive radiosonde networks for longer-term monitoring in such environment given careful cross-instrument calibration.
Perspectives
This paper deals with many technique details in retrieval algorithm and bias correction. With helps from my co-authors, experts in this field, and anonymous reviewers, I was able to put this paper together after overcoming many obstacles. I thank them for such guidance and criticism to better this study.
