“…These authors have reported that given the relatively high level of water at the study site, the decline in LE during the dry period was presumably caused most by a decline in soil evaporation rather than by a decrease in transpiration of trees (due to the increased amount of flood water during the rainy season). Similar results were observed in wetlands of Everglade humid subtropical (Shoemaker and Sumner 2006). These results suggest that patterns of LE for Cambarazal are more similar to the lowland Amazon rainforest than other tropical forests in the same region (Rodrigues et al 2011).…”

Matter and energy flux dynamics of wetlands are important to understand environmental processes that govern biosphere-atmosphere interactions across ecosystems. This study presents analyses about hourly interaction between wind speed and energy fluxes in Brazilian Wetlands -Mato Grosso -Brazil. This study was conducted in Private Reserve of Natural Heritage (PRNH SESC, 16º39'50''S; 56º47'50''W) in Brazilian Wetland. According to Curado et al. (2012), the wet season occurs between the months of January and April, while the June to September time period is the dry season. Results presented same patterns in energies fluxes in all period studied. Wind speed and air temperature presented same patterns, while LE was relative humidity presented inverse patterns of the air temperature. LE was predominant in all seasons and the sum of LE and H was above 90% of net radiation. Analyses of linear regression presented positive interactions between wind speed and LE, and wind speed and H in all seasons, except in dry season of 2010. Confidence coefficient regression analyses present statistical significance in all wet and dry seasons, except dry season of 2010, suggest that LE and H had interaction with other micrometeorological variables.

“…In the Everglades wetlands located just north of Florida Bay, Shoemaker and Sumner (2006) report errors in estimating evapotranspiration ranging from 9 to 27% for the long-term radiation method (Equation 6) and 11 to 37% for the phase. Salinity at seawater strength will decrease evaporation by 4% relative to evaporation from fresh water (Steinhorn 1991).…”

Variation and uncertainty in estimated evaporation was determined over time and between two locations in Florida Bay, a subtropical estuary. Meteorological data was collected from September 2001 to August 2002 at Rabbit Key and Butternut Key within the bay.Evaporation was estimated using both vapor-flux and energy-budget based methods. The results were then placed into a long-term temporal context using 33 years of temperature and rainfall data collected in south Florida. Evaporation also was estimated from this long-term data using an empirical formula relating evaporation to clear sky solar radiation and air temperature.Evaporation estimates for the 12 month period ranged from 144 to 175 cm yr -1 , depending on location and method, with an average of 163 cm yr -1 ("9%). Monthly values ranged from 9.2 cm to 18.5 cm, with the highest value observed in May, corresponding with the maximum in measured net radiation. Uncertainty estimates derived from measurement errors in the data were as much as 10%, and were large enough to obscure differences in evaporation between the two sites. Differences among all estimates for any month indicate the overall uncertainty in monthly evaporation, and ranged from 9% to 26%. Over a 33-year period (1970 -2002), estimated annual evaporation from Florida Bay ranged from 148 to 181 cm yr -1 , with an average of 166 cm yr -1 . Rainfall was consistently lower in Florida Bay than evaporation, with a long-term average of 106 cm yr -1 Rainfall considered alone was uncorrelated with evaporation at both monthly and annual time scales; however, when the seasonal variation in clear sky radiation also was taken into account both net radiation and evaporation were significantly suppressed in months with high rainfall.

“…Shoemaker and Sumner (2005) derived a new approach for computing changes in heat energy stored in wetland surface water, a considerable component of subdaily and daily surface-energy budgets. Shoemaker and Sumner (2006) also developed numerous corrections for estimating actual wetland ET derived from potential ET. Price and others (2007) have considered the uncertainty associated with evaporation estimates due to measurement error, and estimated a mean annual evaporation of about 1,700 mm/yr from Florida Bay over a 33-year period.…”
