ParFlow.CLM model input files of six headwater catchments of the Gwynns Falls watershed, Baltimore County, Maryland, USA

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.

本项研究采用ParFlow.CLM模拟了位于美国马里兰州巴尔的摩县Gwynns Falls流域的六处源头流域。模拟过程中，采用了10米水平的网格划分，流域面积介于0.2至2平方公里之间。垂直方向上的离散化从0.1至8米不等，并激活了ParFlow.CLM的地形跟随网格功能。模型域包含了69,120至505,440个有限差分单元。模拟时间跨度为2012年1月1日至2015年12月31日。每个压缩的tar存档文件（.tar.gz）包含了执行模型运行所需的输入数据，包括：渗透率、坡度和地质单元指示字段所需的ParFlow二进制文件（.pfb）、用于输入参数的CLM文本文件（.dat和.txt）、一维NLDAS2强迫项、植被矩阵和植被参数，以及用于生成模型输入数据库的ParFlow输入tcl文件（.tcl）。此外，还包括了一个包含模型尺寸的Bash外壳脚本（.sh）。
