摘要

本研究的目的是利用modis获取的水面温度(产品MOD11A1)和水面气象数据，研究巴西中部Itumbiara水库的蒸发动力学。蒸发速率由潜热通量导出，通过传质模型估算。这些估计数是在2010年1月1日至2010年12月31日期间进行的。结果表明:1 - 9月蒸发速率呈先增大后减小的趋势;伊通比亚拉的蒸发速率接近20毫米/天

Avaliação da dinâmica temporal da evaporação no reservatório de Itumbiara, GO, utilizando dados obtidos por sensoriamento remoto

The object of this work was to study the dynamics of evaporation in the Itumbiara reservoir, located in Central Brazil, using MODIS-derived water surface temperature (product MOD11A1) and meteorological data acquired over the water surface. The evaporation rates were derived from latent heat flux, estimated through a mass transfer model. The estimates were carried out for the period between 1/1/2010 and 31/12/2010. The results showed that evaporation rate tends to increase from January to September and then decrease from September to December. The evaporation rate reached values near 20 mm day -1 in Itumbiara
