The anomaly index uses daily Soil Water Index to quantify the moisture condition at various depths in the soil. It is mainly driven by precipitation via the process of infiltration. The data is available at 10km resolution, based on SSM (Surface Soil Moisture) observations from MetOp-ASCAT satell...

Detecting spatio-temporal changes in the extent of seasonal and annual flooding in South Asia using multi-resolution satellite data
Floods are one of the most frequent and widespread natural hazards in the world. A recent example is the 2011 floods in three of the four Lower Mekong Basin Countries (Thailand, Cambodia and Vietnam) that caused severe impacts in terms of loss of life and damage to infrastructure. Several studies...
