2009年，阿拉巴马大学亨茨维尔分校将他们的GO卫星太阳辐射产品配置为包括波多黎各、美属维尔京群岛(USVI)、多米尼加共和国、海地、牙买加和古巴。波多黎各和美属维尔京群岛的半小时和每日综合数据的分辨率为1公里，伊斯帕尼奥拉、牙买加和古巴的分辨率为2公里。这些数据使在所有岛屿上实施基于卫星辐射的蒸散方法的估算成为可能。太阳辐射数据的使用与其他气候参数的估计相结合，促进了波多黎各水和能量平衡算法的制定。本文的目的是描述估算日水热平衡各组成部分的理论背景和技术方法。运作中的水和能量平衡模式在波多黎各尚属首例。模型验证结果用于参考和实际的蒸散量、土壤湿度和径流量。所有分析的平均误差都不到7%。水能平衡模型成果可惠及农业、生态、沿海水资源管理、人类健康、可再生能源开发、水资源、干旱监测、灾害与应急管理等多个领域。这项研究是为加勒比地区开发一套网格化水文气候产品的初步步骤。
In 2009, the University of Alabama-Huntsville configured their GOES satellited-based solar radiation product to include Puerto Rico, the US Virgin Islands (USVI), Dominican Republic, Haiti, Jamaica, and Cuba. The half-hourly and daily integrated data are available at 1 km resolution for Puerto Rico and the USVI and 2 km for Hispaniola, Jamaica, and Cuba. These data made it possible to implement estimates of satellite radiation-based evapotranspiration methods on all of the islands. The use of the solar radiation data in combination with estimates of other climate parameters facilitated the development of a water and energy balance algorithm for Puerto Rico. The purpose of this paper is to describe the theoretical background and technical approach for estimating the components of the daily water and energy balance. The operational water and energy balance model is the first of its kind in Puerto Rico. Model validation results are presented for reference and actual evapotranspiration, soil moisture, and streamflow. Mean errors for all analyses were less than 7%. The water and energy balance model results can benefit such diverse fields as agriculture, ecology, coastal water management, human health, renewable energy development, water resources, drought monitoring, and disaster and emergency management. This research represents a preliminary step in developing a suite of gridded hydro-climate products for the Caribbean Region.
