Gridded 20-year Parameterization of a Stochastic Weather Generator (CLIGEN) to Fill Gaps in Coverage in the Northern Hemisphere

CLImate GENerator (CLIGEN) is a stochastic weather generator that produces weather time series for soil erosion modeling and various other applications. The generated time series are statistically similar to observed long-term time series. This gridded CLIGEN parameterization with 0.25° spatial resolution complements existing global coverages by filling in remaining gaps that existed in the northern hemisphere (see the map layer *.kmz file with all grid point locations). The coverage is largely represented by Canada, Europe, and Russia and encompasses countries north of ~40°N with no previous known coverage. The CLIGEN inputs may be used to generate daily precipitation, temperature, dewpoint, solar radiation, and wind time series, as well as sub-daily precipitation patterns. The gridded parameterization allows CLIGEN time series to be generated at any point the grid. In particular, the dataset can provide climate drivers for climate-related research in ungauged areas where observed climate records are unavailable.
The data are formatted as CLIGEN *.par files, which are the only required input for CLIGEN. The files are contained in the "Grid Files" download with n=114,150 files corresponding to the total number of grid points. The files are labeled according to grid point lat/lon coordinates (WGS84) in decimal degrees. The labeling convention uses 'N' and 'E' (north, east) to represent coordinates with a positive sign and 'S' and 'W' (south, west) to represent coordinates with a negative sign.

CLImate GENerator (CLIGEN)乃一款随机天气生成器，旨在为土壤侵蚀模拟及其他各类应用生成气象时间序列。所生成的时序数据在统计学上与观测到的长期时序数据相似。该具有0.25°空间分辨率的网格化CLIGEN参数化模型，通过填补北半球剩余的空白，补充了现有的全球覆盖范围（参见地图层*.kmz文件，其中包含所有网格点位置）。该覆盖范围主要涵盖加拿大、欧洲和俄罗斯，并包括北纬约40°以北的国家，这些地区此前尚未有已知覆盖。CLIGEN的输入可用于生成每日降水量、温度、露点、太阳辐射和风速时间序列，以及亚日降水量模式。网格化参数化使得CLIGEN时间序列可生成于网格的任何一点。特别是，该数据集能够为无观测气候记录的未测区域提供气候驱动因素，以支持气候相关研究。
数据格式为CLIGEN *.par文件，这是CLIGEN的唯一必需输入。这些文件包含在“Grid Files”下载中，共有n=114,150个文件，对应于总网格点数。文件根据网格点纬度/经度坐标（WGS84，十进制度）进行标记。标记惯例使用‘N’和‘E’（北，东）来表示正号坐标，而‘S’和‘W’（南，西）则用于表示负号坐标。
