Water: calculated climatic balance
Republic of Moldova · 01 Apr 2026 — 30 Sep 2026
Full territory and locality catalogue →
Territorial profiles use complete seasons: 1 April–30 September. Water calculations are available for 2026; climate history is shown by year.
Precipitation 278.0 mm; estimated ET0 804.4 mm; climatic water balance P−ET0 -526.3 mm. Reference evapotranspiration exceeds precipitation. Compare crop and soil-water storage scenarios before sizing irrigation. ET0 and P−ET0 are calculated per cell and weighted across the territory. A negative balance means precipitation is below reference evapotranspiration. Compare a scenario with explicit crop, soil, area and efficiency; water-source verification remains separate.
Geographic-area weighted mean, without a cropland mask. Model data, not field measurements.
Precipitation (P) and reference evapotranspiration (ET0). Values and assumptions are detailed below.

Water balance indicators
Each index is calculated within each native cell before averaging by its intersection area. Day counts may be fractional. Maxima, minima and spells are means of cell indices, not extremes for the whole territory.
| Indicator | Value | Unit | Status |
|---|---|---|---|
| Total precipitation | 278.05 | mm | Calculation from model data |
| Reference evapotranspiration ET0 | 804.37 | mm | Model estimate |
| Climatic balance P−ET0 | -526.32 | mm | Model estimate |
Monthly dynamics
kRs=0.16 is the inland assumption; 0.19 is only a sensitivity alternative. Their difference is not a confidence interval and does not cover all uncertainty. Local accuracy is not calibrated.
| Period | P · mm | ET0 · mm | P−ET0 · mm | ET0 · kRs=0.19 · mm |
|---|---|---|---|---|

Irrigation project conditions
Climate calculations work independently. The five areas below require specific evidence before a project decision.
| Area | Evidence needed |
|---|---|
| Water-source locations | Dated map, seasonal flow and usable volume; water surface area does not establish availability. |
| Water quality | Dated laboratory analysis, sampling point and parameters relevant to the crop and soil. |
| Permits | Valid document, holder, source and abstraction limits; a thematic map is not a permit. |
| Infrastructure | Inspection, capacity, losses and energy use; a mapped feature does not establish operation. |
| Economics | Documented CAPEX/OPEX, energy/water prices, area, efficiency and dated prices; benefits remain scenarios. |

- Geographic-area weighted mean, without a cropland mask. Model data, not field measurements.
- The MERRA-2 reference for 1991–2020 is available separately. The 2026 anomaly and rank are withheld because source homogeneity is unconfirmed. Historical comparisons describe past conditions; they do not validate a forecast model.
- geoBoundaries ADM1 outlines, 2020; CUATM codes from the BNS CUATM_25.xlsx file. Current legal boundary equivalence and field boundaries are not established.
- Days with negative modelled net longwave radiation or mean dew-point temperature above minimum temperature are flagged. Daily aggregates differ; original values are not changed without documentation.
- FAO 56: albedo = 0.23; daily soil heat flux G = 0; T = (Tmax + Tmin)/2; ea is calculated from mean dew-point temperature. Wind is at 2 m; use of the 0.5 m/s method minimum is flagged. Rs/Rso is capped at 1. Missing radiation is estimated using Equation 50; −999 is not replaced with zero.
- P−ET0 excludes soil, roots, crop, runoff and water storage. Source flow, quality, permits, yield and credit risk are not inferred.
