GMELT Ahead: Leveraging Earth Observations for Improved Climate Projections in High Mountain Asia is a 3-year project to generate high-resolution projections of future climate and hydrology that grounded in best-available historical observations and understanding of atmospheric processes. Different approaches are used for downscaling, including regionalization and Convolutional Neural Network (CNN) pattern reconstruction.

2019 – 2022 Multi-scale Prediction of Flash Drought in the United States
Department of Earth and Planetary Sciences (EPS), Johns Hopkins University (JHU), Baltimore, Maryland, USA
PREEVENTS Track 2: Collaborative Research: Flash droughts: process, prediction, and the central role of vegetation in their evolution is a 3-year project to advance efforts to understand and forecast flash droughts (FD) by targeting three characteristic features: (1) land surface memory is a key component of FD, (2) evaporative demand is a leading driver of FD onset, (3) vegetation plays a central role in FD development through its influence on soil moisture and turbulent heat fluxes. Deep Learning algorithms are used for the prediction and classification of flash droughts.

2017 – 2020 Applications of Deep Learning to S2S Prediction & Downscaling
