WebFor some impacts proper skill assessment is hindered by lack of high quality, spatially distributed observations, most notably so for crop yields (in Eastern Africa) so obtaining suitable datasets would strongly increase the potential for seasonal timescale food security assessments in these regions. 4.2 Service Development 4.2.1 Our user landscape Web13 de abr. de 2024 · 13 April 2024. Sarah Kang. Eos - AGU. Subseasonal weather forecast ensembles are a useful tool for overcoming the inherent difficulty of quantifying extreme weather risk caused by data scarcity. Assessing the risk of extreme weather events is crucial for our society, but it is incredibly challenging due to their sporadic nature.
