The added-value of remotely-sensed soil moisture data for agricultural drought detection in Argentina
2021
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Preserved Fulltext
In this research we explored the performance of the satellite-based Soil Moisture Agricultural Drought Index (SMADI) for agricultural drought detection in Argentina during 2010-2015, and compared it with ...
Furthermore, field precipitation-based indices, yet simple and widely used, showed not to be suitable indicators for detection of agricultural drought for Argentina, neither in the 1-month nor in the 3 ...
Yet our results underline the value of using readily-available satellite-based soil moisture products for early detection of agricultural drought. ...
