利用GOES-8卫星观测所得的入射太阳辐射，结合当地气象测量，模拟了湿地的蒸散发。湿地实验是在佛罗里达州中北部的佩恩斯草原保护区进行的，当时正值对流活动显著的生长季节。卫星的太阳辐射测量结果与现场收集的太阳辐射计数据基本一致。卫星净辐射估计值与实测净辐射计数据的30分钟平均值非常吻合。Penman-Monteith和Priestley-Taylor模式使用卫星获得的净辐射估计值来计算蒸散发。计算得到的瞬时蒸发通量与地面涡相关系统30分钟平均测量值吻合较好。模拟蒸散发的日平均值与参考涡旋通量测量值非常吻合（r(2) = 0.90）。(C) 2002 Elsevier Science B.V.版权所有
Incoming solar radiation derived from GOES-8 satellite observations, in combination with local meteorological measurements, were used to model evapotranspiration from a wetland. The wetland experiment was conducted in the Paynes Prairie Preserve, North Central Florida during a growing season characterized by significant convective activity. The satellite solar radiation measurements generally agreed with pyranometer data gathered at the site. The satellite net radiation estimates were in good agreement with the 30-min averages of measured net radiometer data. Satellite derived net radiation estimates were used in the Penman-Monteith and Priestley-Taylor models to calculate evapotranspiration. The calculated instantaneous evaporative fluxes were in good agreement with 30-min average ground-based eddy correlation system measurements. The daily averages of modeled evapotranspiration were in very good agreement (r(2) = 0.90) with reference eddy flux measurements. (C) 2002 Elsevier Science B.V. All rights reserved.
