This dataset includes the local precipitation recycling ratios and the regional moisture recycling ratios for five major Mediterranean-type climate regions across the globe. Below we list these five regions and explain the concepts of local precipitation recycling and regional moisture recycling.
Mediterranean-type climate regions
Region 1: South West Australia
Region 2: West coast of the US (California)
Region 3: Central Chile
Region 4: Mediterranean Basin (region around the Mediterranean Sea)
Region 5: The Cape region of South Africa
Local precipitation recycling ratio
The local precipitation recycling ratio is the fraction of precipitation that originated within approximately 50 km from where it rains out, i.e., it evaporated from the grid cell where it rains out and the 8 surrounding grid cells. The grid cells have a resolution of 0.5DEGx0.5DEG. A more detailed explanation is provided in the journal article Theeuwen et al. (2024).
The files that include local precipitation recycling ratios are:
| File name | Study region | Time dimension (month) | Latitude range | Longitude range |
| PLMR_SWAustralia.nc | South West Australia | January-December | -15:-48 DEGN | 106:154 DEGE |
| PLMR_California.nc | West coast of the US (California) | January-December | 52:20 DEGN | -131:-105 DEGE |
| PLMR_CentralChile.nc | Centra Chile | January-December | -10:-54 DEGN | -80:-60 DEGE |
| PLMR_Med_Basin.nc | Mediterranean Basin | January-December | 48:23 DEGN | -20:-45 DEGE |
| PLMR_SWCapeSA.nc | The Cape region of South Africa | January-December | -26:-40 DEGN | 10:38 DEGE |
Regional moisture recycling ratio
The regional moisture recycling ratio data includes both regional evaporation recycling ratios as well as regional precipitation recycling ratios.
The regional evaporation recycling ratio is the fraction of evaporated water that rains out within the Mediterranean region it evaporated from.
The regional precipitation recycling ratio is the fraction of precipitation that originated from the Mediterranean region it rains out in.
This data has a resolution of 0.5DEGx0.5DEG and is a multi-year average (years: 2008-2017). A more detailed description is provided in the journal article Theeuwen et al. (2024).
