Supporting Data for "Interhemispheric Footprint on Indian Monsoon Floods"

This repository contains the supporting data in the NetCDF format for the following paper: Joshi, R. et al. Interhemispheric Footprint on Indian Monsoon Floods. submitted to Geophysical Research Letters In this study, we investigated the rainfall characteristics and dynamical conditions associated with Indian summer monsoon flood years, with particular emphasis on those occurring in the absence of La Niña (NLN+Fl). Note: The rainfall and sea surface temperature (SST) data are publicly available and can be downloaded from the links mentioned in the Open Research Statement in the Article File. This file contains the description of the ERA20C data used in this study. The data correspond only to main Figures 4 and 5, as well as Figures S3 to S9.
