Reference evapotranspiration definition

Reference evapotranspiration or “ETo” means a standard measurement of environmental parameters which affect the water use of plants. ETo is given expressed in inches per day, month, or year as represented in Appendix C of these Guidelines, and is an estimate of the evapotranspiration of a large field of four to seven-inch tall, cool-season grass that is well watered. Reference evapotranspiration is used as the basis of determining the Maximum Applied Water Allowances.

Reference evapotranspiration means a standard measurement of environmental parameters which affect the water use of plants. ETo is given in inches per day, month, or year and is an estimate of the ETo of a large field of four-inches to seven-inch tall, cool season turf that is well watered. Reference ETo is used as the basis of determining the MAWA so that regional differences in climate can be accommodated.

Reference evapotranspiration or “ETo” means a standard measurement of environmental parameters which affect the water use of plants. ETo is expressed in inches per day, month, or year as represented in Appendix A of the landscape guidelines, and is an estimate of the evapotranspiration of a large field of four- to seven-inch tall, cool- season grass that is well watered. Reference evapotranspiration is used as the basis of determining the maximum applied water allowance so that regional differences in climate can be accommodated.

Examples of Reference evapotranspiration in a sentence

• Reference evapotranspiration (ETo) is used as the basis of determining the Maximum Applied Water Budget.

• Reference evapotranspiration is used as the basis of determining the Maximum Applied Water Allowances so that regional differences in climate can be accommodated.

• The reference evapotranspiration is calculated by using climatic data, with the Penman-Monteith equation: ETc = Kc × ETo (1) where ETc = Crop evapotranspiration ETo = Reference evapotranspiration Kc = Crop coefficient.

• Reference evapotranspiration is used as the basis of determining the Maximum Applied Water Allowances so that regional differences in climate can be accommodated.(rrr) “Regional Water Efficient Landscape Ordinance” means a local Ordinance adopted by two or more local agencies, water suppliers and other stakeholders for implementing a consistent set of landscape provisions throughout a geographical region.

• Reference evapotranspiration - A standard calculation of the quantity of water transpired by a reference crop and evaporated from adjacent soil surfaces as measured by the California Irrigation Management Information System (CIMIS) of weather stations.
