SnowModel Pan-Arctic Data 1979-2009

This data set contains pan-Arctic snow property estimates of distributed air temperature, snow precipitation, snow-season timing and length, maximum snow water equivalent depth (SWE), average snow density, snow sublimation, and rain-on-snow events. These estimates are a result of using National Aeronautics and Space Administration - Modern-Era Retrospective Analysis for Research and Applications (NASA-MERRA) atmospheric reanalysis, land cover and topography data in conjunction with the MicroMet and SnowModel modeling tools. These data are in 3-hourly 10 km horizontal gridded fields from 1 August 1979 through 31 July 2009.

本数据集收录了泛北极地区分布式的空气温度、降雪量、积雪季节的起始与持续时间、最大积雪水当量深度（SWE）、平均积雪密度、积雪升华以及雨夹雪事件的估计值。这些估计值是通过结合使用美国国家航空航天局（NASA）的现代化回顾性分析研究与应用项目（Modern-Era Retrospective Analysis for Research and Applications，简称NASA-MERRA）大气再分析、地表覆盖和地形数据，以及MicroMet和SnowModel模型工具所得。数据以每3小时一次、10公里水平网格形式，自1979年8月1日至2009年7月31日提供。点击以下文档列表中的参数字典（Parameter_Dictionary.html），可查看参数列表及数据可用的时间表。
