Greengage ParFlow.CLM model input files

Six headwater catchments of the Gwynns Falls watershed, located in Baltimore County, Maryland, USA, were simulated using ParFlow.CLM. We utilized a 10-m horizontal gridding, with catchment areas ranging on the order of 0.2 to 2 sq. km. Vertical discretization was variable ranging from 0.1 to 8m with the terrain-following grid feature of ParFlow.CLM activated. Model domains contained 69,120 to 505,440 finite difference cells. The simulation period was 1 January 2012 to 31 December 2015. Each compressed tar archive (.tar.gz) contains the inputs required to execute the model run. These include: ParFlow binary files (.pfb) for permeability, slope and geologic unit indicator field, CLM text files (.dat and .txt) for input paramaters, 1-D NLDAS2 forcing, vegetation matrix and vegetation parameters, and a ParFlow input tcl file to generate model input database (.tcl). A Bash shell script (.sh) containing model dimensions is also included.本研究以美国马里兰州巴尔的摩县格温尼斯福尔斯（Gwynns Falls）流域的6处源头集水区为研究对象，采用ParFlow.CLM模型开展数值模拟工作。模拟采用10米水平网格分辨率，各集水区面积介于0.2至2平方千米区间内。模型垂直分层采用可变间距，范围为0.1至8米，并启用了ParFlow.CLM的地形跟随网格功能。模拟域的有限差分单元数量介于69120至505440之间。模拟时段为2012年1月1日至2015年12月31日。 每个压缩tar归档文件（.tar.gz）均包含模型运行所需的全部输入数据，具体包含以下内容：用于表征渗透率、坡度及地质单元标识场的ParFlow二进制文件（.pfb）；用于输入参数的CLM文本文件（.dat与.txt）；一维NLDAS2强迫数据、植被矩阵与植被参数；以及用于生成模型输入数据库的ParFlow输入TCL脚本文件（.tcl）。此外还附带了包含模型维度信息的Bash shell脚本文件（.sh）。
