    UNOSAT code FL20220424SSD This map illustrates cumulative satellite-detected water using VIIRS in South Sudan between 10 to 14 June 2023 compared with the period from 01 to 05 June 2023. Within the cloud free analyzed areas of about 615,000 km², a total of about 11,000 km² of lands appear to be affected with flood waters. Water extent appears to have increased of about 1,000 km² since the period between 01 to 05 June 2023. Based on Worldpop population data and the maximal flood water extent ~205,000 people are potentially exposed or living close to flooded areas.

    This dataset includes an estimate of global drought annual repartition based on Standardized Precipitation Index. It is based on two sources: 1) A global monthly gridded precipitation dataset obtained from the Climatic Research Unit (University of East Anglia). 2) A GIS modeling of global Standardized Precipitation Index based on Brad Lyon (IRI, Columbia University) methodology. This product was designed by UNEP/GRID-Europe for the Project of Risk Evaluation, Vulnerability, Information & Early Warning (PreView). It was modeled using global data. Credit: UNEP/GRID-Europe.
