Dr Sandip Dhomse

Profile

I completed my PhD at the University of Bremen, Germany, focusing on the dynamical influence on stratospheric ozone and water vapour. Following this, I worked on developing an algorithm to retrieve stratospheric water vapour using SCIAMACHY (SCanning Imaging Absorption SpectroMeter for Atmospheric CHartographY) limb measurements.
Since 2008, I have been working at the University of Leeds on various aspects of atmospheric model development and evaluation, using a wide range of satellite data. The atmospheric chemistry models I work with include TOMCAT, UMSLIMCAT, and UMUKCA, which are widely used in global climate assessments.
My research spans atmospheric chemistry, dynamics, climate modelling, and satellite data analysis, with a particular focus on ozone recovery and aerosol interactions. I have extensive experience in quantifying external climate forcing—such as solar variability and volcanic eruptions—as well as anthropogenic forcing from ozone-depleting substances (ODSs) and hydrofluorocarbons (HFCs). My work bridges stratospheric and tropospheric processes, contributing to a deeper understanding of climate variability and the effectiveness of environmental policies like the Montreal Protocol.
In recent years, I have been using machine learning techniques to construct long-term atmospheric datasets by fusing satellite observations with chemical transport model outputs. This approach improves the consistency and coverage of key atmospheric variables, enabling better analysis of trends and variability in stratospheric composition and dynamics. In August 2025, I completed the Level 7 AI and Data Science Apprenticeship, further strengthening my ability to integrate advanced data science methods into climate research.
I have authored over 120 peer-reviewed publications and contributed to several international reports, including multiple ozone assessment reports. I currently serve as an editor for Atmospheric Measurement Techniques (AMT) and for the Encyclopedia of Atmospheric Sciences, Third Edition (Chemistry Section), supporting the advancement of high-quality research in climate and atmospheric sciences.
