    UNOSAT code FL20230606UKR This map illustrates cumulative satellite-detected water using ICEYE images and Sentinel-3 images acquired between the 06th and the 09th of June 2023. Within the analysed area of 19,000 km², about 620 km² of land appear to be flooded. Based on Worldpop population data from 2020 and the flood water extent, ~110,000 people are potentially exposed or living close to flooded areas. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT). Important note: Population data used for this estimate is from 2020. Current population count is not available.

    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.
