Then, local microclimate data are used to determine a standardized reference evapotranspiration for the local microclimate (Em).
GDAS ETo is the sum of evaporation from the soil surface and transpiration from a standardized reference clipped grass surface fully covering the ground (Allen et al. 1998).
Actual crop coefficients (Kco_act) were determined using the ratio of the actual ET (ETa) and the standardized reference ET (ETo) equation of the American Society of Civil Engineers.
Although there are several serological tests with different diagnostic performance and capacity to differentiate vaccinated from infected animals, there is still no standardized reference antigen for the disease.
Comparing to standardized reference evapotranspiration (ETo), the annual (ETa/ETo lys ratios in 2005 were 0.98 for TWG, 0.92 for CWR, and 0.85 for Paspalum.
The role of guardians need not be an individual, such as a law enforcement officer, and could include standardized reference samples, test methods, corporate market monitoring, supplier audits, or transparency created by quality control programs.
This measurement approach, and the associated lack of reproducibility, is not compatible with ambulatory monitoring and it is further recognized that precise, standardized reference points are required for the more meaningful monitoring of the lower leg.
The most notable and recent attempt towards formulating such Architecture is the work that is being done within the EU funded project FREIGHTWISE30 which aims to produce a standardized reference model for intermodal freight transport operation in terms of standardized roles, functions, processes and messages.
Abdominal girth was measured in duplicate using standardized reference points.
We denoted this concept "seasonally standardized reference period or days".
