North American watershed precipitation from WRF

Precipitation estimates from the Weather Research and Forecasting (WRF) regional climate model. Each file contains the following variables for the stated watershed: lat: latitude of each grid point, in degrees north lon: longitude of each grid point, in degrees north time: day of simulation RAINC: accumulated total cumulus precipitation, in mm RAINNC: accumulated total grid scale precipitation, in mm SNOWNC: accumulated total grid scale snow and ice, in mm watershed mask: matrix where 1 indicates the grid point is inside the watershed, 0 is outside watershed mountain mask: matrix where 1 indicates the grid point is within the mountainous portion of the watershed, 0 is outside本数据集包含来自天气研究与预报（Weather Research and Forecasting, WRF）区域气候模式的降水估算结果。每个文件针对指定流域包含以下变量： lat：各网格点的纬度，单位为北纬度数 lon：各网格点的经度，单位为北纬度数 time：模拟的日期 RAINC：累积对流总降水量，单位为毫米 RAINNC：累积网格尺度总降水量，单位为毫米 SNOWNC：累积网格尺度总冰雪量，单位为毫米 watershed mask：流域掩码矩阵，其中1表示该网格点位于流域内，0表示位于流域外 watershed mountain mask：流域山地掩码矩阵，其中1表示该网格点位于流域的山地范围内，0表示位于范围外
