South Asia 8-Day Drought Extent 16 Oct - 23 Oct 2010

Abstract

The International Water Management Institute (IWMI) produces Integrated Drought Severity Index (IDSI) every 8-day and provide regional to district scale information about drought’s effect on agriculture. IDSI cover Afghanistan, Bangladesh, Bhutan, India, Nepal, Pakistan and Sri Lanka, covering the whole of South Asia. The IDSI calculations integrate satellite-based observations of vegetation conditions and climate data and other biophysical information such as land cover/land use type, topography and river basin details. The IDSI maps that are produced deliver continuous geographic coverage over large area for the first time, and have inherently finer spatial detail (500m resolution) than other commonly available global drought products such as NESDIS NOAA, MODIS Global Terrestrial Drought Severity Index using different data and approaches
