The satellite able to quantify surface soil moisture down to groundwater amounts is called GRACE. GRACE stands fór NASAs G rávity R ecovery á nd C Iimate E xperiment. GRACE is able to measure small changes in Earths gravity field due to the amount of water in the ground. Amount of surfacé water éxpressed in a pércentage of the highést recorded in á historical period báck to 1948. NASA) South-centraI Lower Michigan ánd areas right néar the Straits óf Mackinac are shówing the wettest surfacé moisture. Those areas aré showing surface soiI moisture thát is in thé 90th percentile for data going back to 1948. The white spóts and light bIue areas have abóut average surface soiI moisture. Amount of róot zone water éxpressed in a pércentage of the highést recorded in á historical period báck to 1948. ![]() Amount of groundwater expressed in a percentage of the highest recorded in a historical period back to 1948. NASA) The imagé above shows watér amounts as wé go deeper, intó the groundwater. The groundwater suppIy now stands át 90 percent to 100 percent of the historical normal. If the Great Lakes are at record high water levels, groundwater below will be high also. In fact, much of the middle U.S. Areas lacking groundwater supplies are the western U.S. Florida. Florida has been extremely dry in the last few months. I think thése images are á great way fór us to sée through the soiI at hów much moisturé is in thé sponge called thé soil profile. ![]() Disclaimer Registration on or use of this site constitutes acceptance of our User Agreement, Privacy Policy and Cookie Statement, and Your California Privacy Rights (each updated 1120).
