Fig. 1. (a) Composited vertical profiles of potential temperature from the thermocouple data and vertical profiles of the wind speed fromthe sonic anemometers between 21:00–05:00 h local time for late summer (15 August–19 September.)
Fig. 2. For 15 August–19 September 1994, (a) the heat flux (Hheat flux at 5.5 and 39 m, (c) the friction velocity and wind speed above the canopy (39 m) and in the subcanopy (5.5 m) based on thesonic anemometers, (d) the evolution of the canopy inversion strength (), the net radiation and the air temperature at the 39 m level, (b) the◦C), the subcanopy surface inversion strength and the subcanopyRichardson number where the canopy inversion strength is defined as the difference of potential temperature between the 25 and 19 mlevels and the subcanopy surface inversion strength between the 6.4 and 1 m levels, (e) canopy inversion strength as a function of thesurface friction velocity.

Using a whole year’s worth of data, soil heat flux was estimated by a two-step version of the null-alignment method using soil temperature, water content and bulk density

In Table 1a, 1b and 1c we present the values of effective scintillometer height associated with each method, the corresponding time average value of sensible heat flux as well as

Relationships between sapwood area (m 2 ) and tree basal diameter (m) for cottonwood and willow are shown in Fig. 6 mm per day in young forest.. fremontii ) located on primary

An area-average soil heat flux from the array is compared with a set of three measurements from a standard micro-meteorological station judiciously positioned to obtain

Soil, mulch, and air temperatures were measured with fine-wire thermocouples, the sensible heat flux was determined with an air renewal model from the cubic structure function

The daytime (07:00–18:00 hours) 20 min and hourly latent heat flux values, average evaporation for the earlier mentioned three periods and evaporation on individual days were

The measurements showed that approximately 80% of the incoming net radiation was used as latent heat, reducing to a value between 71 and 76% in the summer months of 1995 and 1996

The objective of this study was to develop a footprint climatology at the FACTS-1 site based on 25 years of data and to use it to estimate potential control ring contamination
