The Impact of the canopy shortwave radiation parameterizations of SUMMA Model at Reynolds Mountain East

This SUMMA Model instance is a part of the Clark et al., (2015b) study, and explored the Impact of the canopy shortwave radiation parameterizations on below canopy shortwave radiation using a SUMMA model for the Reynolds Mountain East catchment. This study looked at four different canopy shortwave radiation parameterizations: BeersLaw method(as implemented in VIC), NL_scatter method(Nijssen and Lettenmaier, JGR 1999:NL 1999), UEB_2stream method(Mahat and Tarboton, WRR 2011:MT 2012), CLM_2stream method(Dick 1983)

本SUMMA模型（SUMMA Model）实例隶属于Clark等人（2015b）的研究工作，该研究针对雷诺山东部集水区（Reynolds Mountain East catchment）搭建SUMMA模型，以探究冠层短波辐射参数化方案对冠层下方短波辐射的影响。该研究共采用四种不同的冠层短波辐射参数化方案：比尔定律法（BeersLaw method，基于VIC模型实现）、NL散射法（NL_scatter method，由Nijssen与Lettenmaier提出，载于《地球物理学研究杂志》1999年，简称NL 1999）、UEB二流法（UEB_2stream method，由Mahat与Tarboton提出，载于《水资源研究》2011年，简称MT 2012）以及CLM二流法（CLM_2stream method，源自Dick 1983）。
