Relative Water Deficit for the Kamping Pouy irrigation scheme command area identified by the ADB project in the Battambang Province of Cambodia. The relative water deficit based on ETa estimated from Landsat 8 OLI and meteo data, averaged over main growing seasons (December to April) 2017, 2018 and 2019.

The map represents the water deficit per pixel computed as 1 minus the ratio of ETa over ETx (max crop ET) over the Samba main growing season (August to December) 2017, for the irrigated command areas identified by the ADB project in Tamil Nadu state of India. The RWD10 image indicates pixels showing up to 10% water deficit. The pixel value in the RWD10 indicates the percentage of time (no. of deficit days/total days in a season) a given pixel experienced up to 10% of the water deficit.

Base flow calculated for the Malaprabha (K4) sub-basin area. Base flow (bf) or slow flow is the component of the total flow that is due to groudwater discharge. It mainly occurs during dry months. The calculation of base flow is based on a pixel-based soil water balance model. More information are available in the IHE Delft water accounting report of Karnataka.

Evapotranspiration from precipitation calculated for the Middle Krishna (K2) sub-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. The calculation is based on a pixel-based soil moisture balance model. More information can be found on the IHE Delft Water Accounting report of Karnataka.

Average storage change over the study area of Mindanao island of Philippines. The dataset has been computed from GRACE data using a central difference scheme. GRACE data processing centre: CSR, JPL and GFZ.

Interception calculated for the Mongolian Selenga River basin and the Selenga drainage area to Naushki, beyond the boundaries of Mongolia. The Interception (I) data component (monthly, in mm/day) represents the evaporation of intercepted rainfall from the vegetation canopy. Interception is the process where rainfall is captured by the leaves. Part of this captured rainfall will evaporate again. The value of each pixel represents the average monthly evaporated interception for that specific month.

The Biomass Water Productivity (WPb) is computed by dividing Biomass by ETa and aggregated over Narayanapur Left Bank Canal (NLBC) in Karnataka state of India for the Kharif season (July to December) over the years 2017, 2018 and 2019.

Actual EvapoTranspiration for the Kamping Pouy irrigation scheme command area identified by the ADB project in the Battambang Province of Cambodia. The Actual Evapotranspiration is estimated from remote sensing energy balance model (SEBAL) on Landsat 8 OLI and meteo data, aggregated over irrigation seasons (December to April) 2017, 2018 and 2019.

The map represents the water deficit per pixel computed as 1 minus the ratio of ETa over ETx (max crop ET) over Narayanapur Left Bank Canal (NLBC) in Karnataka state of India for the Kharif season (July to December) over the years 2017, 2018 and 2019.

Precipitation calculated in the Ghataprabha (K3) sub-basin area, derived from the Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) (ftp://ftp.chg.ucsb.edu/pub/org/chg/products/CHIRPS-2.0/). Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) is a 35+ year quasi-global rainfall data set. Spanning 50°S-50°N (and all longitudes) and ranging from 1981 to near-present, CHIRPS incorporates in-house climatology, CHPclim, 0.05° resolution satellite imagery, and in-situ station data to create gridded rainfall time series for trend analysis and seasonal drought monitoring.
