      <description descriptionType="Abstract">This dataset contains large-scale groundwater storage anomalies for the Sesan and Srepok catchments in the Central Highlands of Vietnam. The anomalies were derived from in-situ groundwater well water level time series and hydrogeological information. A detailed description of the datasets and methods can be found in Sayyadi et al 2025.   <br/>
         <br/>
The dataset is comprised of three files: insitu_groundater_storage_anomalies.csv, GW_wells.csv and a shape file with the Thiessen polygones indicating the extent of the area for which the storage calculations were performed.   <br/>
         <br/>
insitu_groundater_storage_anomalies.csv contains the groundwater storage variations, with the following columns:   <br/>
         <br/>
1.	gws_mm (Groundwater Storage in millimeters): The gws_mm data represent groundwater storage anomalies derived from in-situ well measurements. Groundwater levels were recorded monthly from a network of observation wells across the study area. Specific yield values were used to convert the groundwater level variations into storage anomalies, measured in millimeters of water equivalent.   <br/>
         <br/>
2.	seasonal_adjusted: The seasonal_adjusted data were obtained by removing the seasonal component from the raw groundwater storage time series (gws_mm). This was done by calculating the mean monthly anomalies and subtracting them from the original data to isolate non-seasonal variations.   <br/>
         <br/>
3.	trend: The trend data represent the linear trend component of the groundwater storage anomalies. The trend was calculated using a linear regression model applied to the seasonal-adjusted data, highlighting long-term groundwater storage changes over the study period.   <br/>
         <br/>
4.	detrended: The detrended data were created by removing both the seasonal and long-term trend components from the gws_mm data. This dataset captures short-term fluctuations and anomalies, free from the regular seasonal and trend influences.   <br/>
 GW_wells.csv contains a list of the griundwater wells used in the study, with information about their location and lithology, as well as the range of associated specific yields (sy).   <br/>
         <br/>
Thiessen_polygones_GW_wells_2S.shp is a georeferenced shape sile containing the Thiessen polygones for the wells in GW_wells.csv.   <br/>
