Available Water Capacity for the Upper Colorado River Basin in Maurer et al. (2002) Climate Data resolution (awc_UCRB_Maurer_resolution.asc)

awc_UCRB_Maurer_resolution.asc is an Esri ASCII grid representing the available water capacity (AWC) for the Upper Colorado River Basin. AWC is the amount of water that a soil can hold, and is between a soil’s field capacity and the wilting point. In Soil-Water Balance model recharge simulations, AWC is multiplied by root zone depth to define the maximum water capacity of a cell, and any soil-moisture exceeding this amount is converted to recharge.awc_UCRB_Maurer_resolution.asc 是一款用于表征科罗拉多河上游流域（Upper Colorado River Basin）有效持水量（available water capacity, AWC）的Esri ASCII网格（Esri ASCII grid）。其中，有效持水量（AWC）指土壤所能持存的水量，其取值介于土壤田间持水量与萎蔫点之间。在土壤水平衡模型（Soil-Water Balance model）的补给模拟中，有效持水量会与根区深度相乘，以定义单个网格单元的最大持水量，超出该阈值的土壤水分将被转化为补给量。
