Nationwide Groundwater Recharge Model

Monthly data of 1km x 1km rainfall recharge to groundwater, from Jan-2000 – Dec-2014. The National Groundwater Recharge Model (NGRM) was developed to demonstrate the utility of satellite data and global models by development of a rainfall recharge model that is consistent over all regions of New Zealand. The NGRM has a 1 km × 1 km model grid that covers most of New Zealand and uses a cell-by-cell soil water balance approach to estimate rainfall recharge.
