ABoVE: Monthly Hydrological Fluxes for Canada and Alaska, 1979-2018

This dataset provides modeled estimates of monthly hydrological fluxes at 0.25-degree resolution over Alaska and Canada for the years 1979-2018. The estimates were derived from the Variable Infiltration Capacity (VIC) macroscale hydrological model version 4.1.2 with water and energy balance schemes at 0.25-degree spatial and daily temporal resolution for this 38-year period. The gridded output data products are monthly average water balance variables including precipitation (P), evapotranspiration (E), 'P minus E', evaporation, soil moisture in three soil layers, base flow and runoff, snow depth, snow water equivalent (SWE), and snow sublimation, and energy balance variables including surface temperature, albedo, latent and sensible heat flux, ground heat flux, short- and long-wave and other radiative fluxes. The daily modeled values for precipitation and evapotranspiration were also aggregated to water years and precipitation was also aggregated to a 30-year climate normal average.

本数据集提供了1979年至2018年期间，针对阿拉斯加及加拿大地区，以0.25度分辨率模拟的月度水文通量估算值。这些估算值源于Variable Infiltration Capacity (VIC)宏观水文模型版本4.1.2，该模型采用水热平衡方案，在0.25度空间分辨率和每日时间分辨率下，对这一38年时段进行了计算。网格化输出数据产品包括月平均的水文平衡变量，如降水（P）、蒸散（E）、'P减E'、蒸发、三层土壤中的土壤水分、基流和径流、雪深、雪水当量（SWE）、雪升华，以及能量平衡变量，包括地表温度、反照率、潜热和显热通量、地面热通量、短波和长波及其他辐射通量。此外，对降水和蒸散的日模拟值也进行了年度汇总，同时降水数据也汇总至30年气候平均值。
