Marine heatwaves (MHWs) induce significant impacts on marine ecosystems. There is a
growing need for knowledge about extreme climate events to better inform decision-makers
on future climate-related risks. Here we present a unique observational dataset of MHW
macroevents and their characteristics over the southern Europe and western Asian (SEWA)
basins, named the SEWA-MHW dataset. The SEWA-MHW dataset is derived from the
European Space Agency Sea Surface Temperature Climate Change Initiative (ESA SST …
