This distance is referred to as the fetch, and the fetch requirement is generally considered to be 100 times the height of the sensors above the surface [16]. More detail about determination of the minimum fetch requirement is presented later in this document. Hanks et al. 97 for wet soil conditions; On the other hand he found λE/Rn to be lowest in grazed prairie, suggesting that defoliation changes the canopy structure and energy budget components, which may have contributed to increase water loss through evaporation compared with the nongrazed prairie treatment.

Eq. (21) describes the Penman-Monteith (P-M) method to estimate the λE [5, 54]: λE = ∆s ( Rn − G ) + ρa C p  r  ∆s + γ 1 + s   ra  VPD ra (39) where, λE, Rn, and G in fim-2, VPD is vapor pressure deficit (kPa), ∆s is slope of saturation vapor pressure curve (kPa ◦C–1) at air temperature, ρ is density of air (Kgm–3), Cp in J. Kg–1◦C–1, γ in kPa ◦C–1, ra is aerodynamic resistant (s m–1) rs surface resistance to vapor transport (s m–1). © 2016 by Apple Academic Press, Inc. Water Vapor Flux Models for Agriculture 29 According to Monteith [69], the appearance of a wind-dependent function in the denominator as well as in the numerator implies that the rate of evaporation calculated from the P-M model is always less dependent on wind speed than the rate from corresponding the Penman equation when other elements of climate are unchanged.

3 RADIOMETER Radiometer is a device used to measure the short wave and long wave radiations. 4 NET RADIOMETER It measures the difference between incoming and outgoing. Values are positive during the day and negative at night. 5 µm to 100 µm. Pyrgeometers are frequently used in meteorology and climatology studies. The atmospheric longwave downward radiation is of interest for research into long-term climate changes [1, 2]. The signals are generally detected using a data logging system, capable of taking high-resolution samples in the millivolt range.
