Incremental evapotranspiration (Litani River Basin, Lebanon - Monthly -100m)

Evapotranspiration from precipitation calculated over the Litani River Basin area. The evapotranspiration from precipitation (etrain) is the evapotranspiration of green water, in other words the fraction of the total evapotranspiration that is due to rainfall, calculated on a pixel-based soil moisture balance model. More information can be found on the Water Accounting report of Litani (FAO and IHE Delft, 2019). **Data publication:** 2019-06-01 **Supplemental Information:** No data value: -9999 Unit: mm/month **Citation:** FAO 2018.

Precipitation minus actual evapotranspiration (P-ET) calculated over the Litani River Basin area in Lebanon. The P-ET is the difference between WaPOR precipitation (based on CHIRPS) and the actual evapotranspiration and interception. **Data publication:** 2019-06-01 **Supplemental Information:** No data value: -9999 Unit: mm/month **Citation:** FAO 2018.

Percolation calculated Litani River Basin area in Lebanon. The percolation (perco) is the amount of soil moisture in the root zone that leaks deeper contributing to groundwater recharge. The calculation of percolation is based on a pixel-based soil moisture balance model.

Supplied water calculated over the Litani River Basin area. The supplied water is the amount of water that is artificially or naturally supplied to a pixel generating incremental evapotranspiration and return flow.

The blue evapotranspiration is part of the actual EvapoTranspiration and Interception (ETIa) that is not satified from precipitation but from supply or runoff from other cells or from groundwater. It is calculated by spliting ETIa to rainfall and blue ET using pixel based soil moisture water balance (PixSWAB) model. **Data publication:** 2023-01-25 **Supplemental Information:** No data value: -9999 Unit: mm **Contact points:** Metadata Contact: [FAO-Data](mailto:fao-data@fao.org) Resource Contact: [Solomon Seyoum](mailto:s.seyoum@un-ihe.org) **Resource constraints:** Creative Commons Attribution 4.0 International (CC-BY-4.0) **Online resources:** Download the data from Google Cloud Storage

Incremental evapotranspiration calculated for the Jordan River Basin area. The incremental evapotranspiration is part of the actual evapotranspiration and Interception (ETIa) that is not satified from precipitation but from supply or runoff from other cells or from groundwater. It is calculated by spliting ETIa to rainfall and incremental ET using pixel based soil moisture water balance model. **Data publication:** 2020-06-01 **Supplemental Information:** No data value: -9999 Unit: mm Conversion factor: the pixel value in the downloaded data must be multiplied by 0.1 New dekadal data layers are released approximately 5 days after the end of a dekad. A higher quality version of the same data layer is uploaded after 6 dekads have passed. This final version of the dekadal dataset has a higher quality because gap filling and interpolation processes, where needed, have been based on more data observations. This implies that other temporal aggregations (monthly, seasonal, annual), and layers that depend on those, are updated as well. Practically this means that a final annual aggregation of the most recent full calendar year can only be produced after the end of February. Likewise, the final monthly aggregation of the most recent calendar months can only be produced 2 full months later. **Citation:** FAO 2018. WaPOR Database Methodology: Level 3.
