GRACE Drought - 14km - Weekly¶
Description¶
Scientists at NASAs Goddard Space Flight Center generate groundwater and soil moisture drought indicators each week. They are based on terrestrial water storage observations derived from GRACE-FO satellite data and integrated with other observations, using a sophisticated numerical model of land surface water and energy processes. The drought indicators describe current wet or dry conditions, expressed as a percentile showing the probability of occurrence for that particular location and time of year, with lower values (warm colors)meaning dryer than normal, and higher values (blues) meaning wetter than normal.
