Current Research

My research employs in-situ observations together with radar–lidar measurements from aircraft, surface-, and satellite-based field campaigns to investigate cloud microphysical properties like size parameters, water and ice concentration, etc., through statistical analyses. These insights contribute to improving global climate model predictions, where inaccurate representations of cloud structure and microphysics often lead to significant biases.

A major component of my work focuses on developing simplified cloud microphysical retrieval algorithms and integrating multi-platform observational datasets from diverse instruments. This approach reduces biases in the cloud detection capabilities of remote sensors and supports the advancement of atmospheric observing systems and future field campaigns.

Research Projects

Cross-Platform Comparison of Marine Boundary Layer Cloud and Drizzle Properties over the Southern Ocean Using Airborne, Shipborne, and Satellite Observations

Towards a unified cloud–drizzle retrievals. A single in situ-derived reflectivity–microphysics framework is applied across airborne (SOCRATES), ship-based (MARCUS), and satellite (CloudSat) radars, enabling more coherent multi-platform cloud and drizzle climatologies.

Deriving Empirical Relationships between MBL Cloud Microphysical Properties and Radar Reflectivity Using Airborne In Situ Measurements over the Southern Ocean

Empirical relationships linking effective radius and liquid water content to radar reflectivity are derived in this study, providing a useful reference for retrievals across different observational platforms and microphysical regimes.

Marine Boundary Layer Cloud Boundaries and Phase Estimation Using Airborne Radar and In Situ Measurements During the SOCRATES Campaign over Southern Ocean

This work presented a methodology that uses airborne radar and in situ measurements to identify cloud boundaries and phase for MBL clouds over the SO.

Quantifying the Differences in Southern Ocean Clouds Observed by Radar and Lidar From Three Platforms

This project focused on performing a synergistic analysis of the radar-only and combined radar-lidar observations across the three field campaigns (airborne, surface- and satellite) to compare cloud detection capabilities.

Associations of Trace Gases and Meteorological Parameters and Particulate Matter with Ozone under Smog Conditions

This work investigated the connection between tropospheric Ozone and other pollutants and meteorological conditions during a smog episode in Delhi.
