| Summary: | - Global Groundwater Levels - Annual groundwater level data described in the following publication: Jasechko, S. Seybold, H.S., Perrone, D., Fan, Y., Shamsudduha, M., Taylor, R.G., Fallatah, O., Kirchner, J.W. Rapid groundwater decline and some cases of recovery in aquifers globally. Nature, doi.org/10.1038/s41586-023-06879-8 (2024). Annual groundwater level data are available in cases where we have received permission from a database manager to post annual groundwater level data. These two .csv files contain annual groundwater level data for Afghanistan, Austria, Belgium, Brazil, Bulgaria, Canada (Alberta, British Columbia, Manitoba, Northwest Territories, Ontario, Prince Edward Island, Saskatchewan, Yukon), China, Croatia, Czech Republic, Denmark, France, Germany, Guam, Ireland, Israel, Italy, Latvia, Lithuania, New Zealand, Norway, Paraguay, Poland, Slovenia, Sweden, Switzerland, and the United States (Groundwater Ambient Monitoring and Assessment Program, US Geological Survey's (USGS) National Water Information System, and the Texas Water Development Board). File 1 of 2 entitled \"AnnualDepthToGroundwater.csv\" \"StnID\" - unique number for the monitoring well \"Lat\" - latitude of the monitoring well (in some cases this may be an approximation) \"Lon\" - latitude of the monitoring well (in some cases this may be an approximation) \"IntegerYear\" - calendar year \"DepthToWater_m\" - annual median depth to groundwater (units of metres below reference point and/or groundwater surface) File 2 of 2 entitled \"AnnualGroundwaterElevation.csv\" \"StnID\" - unique number for the monitoring well \"Lat\" - latitude of the monitoring well (in some cases this may be an approximation) \"Lon\" - latitude of the monitoring well (in some cases this may be an approximation) \"IntegerYear\" - calendar year \"GroundwaterElevation_masl\" - annual median groundwater elevation (units of metres above sea level) This material is based on work supported by the National Science Foundation under grant nos.
