“…Theoretically, energy balance closure, ε should be very close to 1.0; however, energy imbalance was often reported. For instance, after the First International Satellite Land Surface Climatology Projects (ISLSCP) Field Experiment (FIFE), various participants [e.g., Strebel et al , 1990; Smith et al , 1992; Nie et al , 1992] pointed out that the uncertainty in locally measured sensible and latent surface heat fluxes may be about 10% to 20% of the total or ∼20–30 W m −2 per day [see also, e.g., Brutsaert and Sugita , 1992a, 1992b; Qualls and Brutsaert , 1996a, 1996b; Sugita and Brutsaert , 1990, 1996]. In a well watered broad‐leaved forest of Nothofagus trees, R n − J − G, where J is heat storage in the canopy, tended to exceed H + LE by 50–150 W m −2 during periods of intermittent cloudiness [ Kelliher et al , 1992].…”

[1] Eddy covariance measurements were conducted on fluxes of moisture, heat, and CO 2 in a near-surface layer over a rice paddy in the central plain of China from 10 June to 20 July 2001. During this period, the canopy height increased from 0.16 to 0.65 m. The study site, typical of the agricultural region in China, was $600 m Â 600 m, was surrounded by similar rice paddies and was flooded throughout the entire experiment. We estimated the zero plane displacement and the roughness length at the end of the experiment to be 0.43 m and 0.027 m, respectively. Aerodynamic roughness length increased with increasing wind speed when the rice height was >0.5 m. On the basis of footprint analysis, we expected >90% of the measured flux (at a height of 3 m above water) to occur within the nearest 600 m of upwind area. We examined daily and seasonal variations in the components of the surface energy balance and in CO 2 flux. Results show that the pattern of energy partition had no obvious variation during the season. Daytime absorption and nighttime release of CO 2 flux by the rice paddy gradually increased as the rice grew. We examined the energy budget closure and found it to be around 0.91. We tested the extended Louis scheme using eddy covariance techniques. It estimated surface stress in good agreement with direct measurements. However, on average, this scheme underestimated sensible heat flux by 10% and latent heat flux by 11%.

“…On the other hand, FIFE took place during the summer in Manhattan, Kansas (Sellers et al, 1988(Sellers et al, , 1992Strebel et al, 1990). Abundant soil moisture and vegetation were present for much of the observation period.…”

The sensitivity of the development of the convective planetary boundary layer (PBL) and the surface layer are examined using a coupled surface parameterization and detailed PBL model. First, the coupling is verified against observations from the First ISLSCP ('International Satellite Land Surface Climatology Project') Field Experiment (FIFE). Results of the sensitivity experiments indicate that the PBL is most sensitive to the amount of soil water content, and the proximity of the soil water content to critical soil texture values (field capacity and wilting point). While vegetation cover is not the most sensitive parameter at the surface, its influence on the surface energy and hydrologic balance is crucial. Model sensitivity to minimum stomata1 resistance, type of soil parameterization and canopy height (surface roughness and displacement depth) is also discussed.

“…HSIS is arranged hierarchically and is broadly compatible with the FIFE Information System (FIS) (Strebel et al, 1990). AI1 data are being entered into HSIS in a standardized format and are being released periodically on CD-ROM, After the data sets are submitted, but before release on CD-ROM, the data are accessible from a central computer in the form in which they were submitted.…”
