AMAZON RIVER BASIN PRECIPITATION, 1972-1992

The Amazon River Basin precipitation grids were derived from data which was collected daily by the gauging network operated by the Divisao Nacional de Aguas e Energia Eletrica (DNAEE, SGAN 603 Modulo J, Anexo DNC, CEP 70.830-030 Brasilia DF, Brazil). The DNAEE provided the Earth Observing System (EOS) Regional Amazon Model (EOSRAM) project with this data for cooperative analysis. The project includes both empirical and modeling studies of rainfall and runoff from sample hillslopes to the entire Amazon basin. The precipitation data is 0.2 degree gridded monthly precipitation data. The data spans the period from January 1972 to December 1992.

本亚马逊河流域降水网格数据源自巴西国家水利与电力局（Divisao Nacional de Aguas e Energia Eletrica, DNAEE，通讯地址：巴西巴西利亚联邦区CEP 70.830-030，SGAN 603 J模块，DNC附件）运营的水文监测网每日采集的观测数据。该局曾向地球观测系统（Earth Observing System, EOS）亚马逊区域模型（EOSRAM）项目提供该数据集，用于合作分析研究。该项目涵盖从典型坡面至整个亚马逊流域的降雨与径流实证研究及数值模拟研究。本次降水数据为分辨率0.2度的网格化月降水数据集，时间跨度为1972年1月至1992年12月。
