Tsegaye Tadesse,
Drought monitoring, specifically groundwater and soil moisture monitoring, is of critical importance to agriculture. NASA’s Gravity Recovery and Climate Experiment (GRACE) based groundwater storage and soil moisture percentile products give a high resolution, nationwide view of these responses to drought. But how accurate are these products? And how well do they monitor different types of droughts in different regions and seasons? Measurement comparisons show GRACE groundwater storage percentile does not accurately monitor actual groundwater levels. However when compared to other well-known drought indicators and stakeholder observations, both GRACE groundwater storage and soil moisture products show skill in drought monitoring and early warning.
