Estimates of the groundwater recharge rate on the Arabian Peninsula

This dataset contains 92 estimates from individual studies for groundwater recharge rates on the Arabian Peninsula. 

Following information is sorted for each study:

Location information: Country, Latitude*, Longitude*

Estimated groundwater recharge rate: Representative value, Lower/Upper estimate range (all in mm/yr)

Estimating methods**

Scale of study: Aquifer scale, Study period, Study years

Credibility***: Confidence, Confidence criteria

(*) Location information was set as the middle point of the study area, in case that spatial coordinates are not given by the authors.

(**) If more than 1 methods were used for the estimation, additional methods were written in "Method_2"

(***) Confidence of estimates was evaluated by the same criteria used in another meta-study for the African continent (MacDonald et al. 2021; https://doi.org/10.1088/1748-9326/abd661) 

This dataset has been used to train the neural network model targeting global-scale estimation of groundwater recharge rate together with datasets used in other meta-studies.
