详细信息----------Details----------
According to SAGA GIS 2.0.7 documentation, "Most options should do well, but TAPES-G based diffuse irradiance calculation ("Atmospheric Effects" methods 2 and 3) needs further revision!" I.e. be careful with method = "components" and
根据SAGA GIS 2.0.7文档,“大多数选项应该做的很好,但TAPES-G的漫散射计算(”大气效果“的方法2和3)需要进一步修改!”,即小心method = "components"
注意----------Note----------
SAGA_CMD uses zero-based days and months, but this R function uses the standard one-based days and months (e.g. day 1 is the first day of the month, month 1 is January) and translates to the SAGA system.
SAGA_CMD使用从零开始的几天和几个月,但这个R函数使用标准的1天,24个月(例如,每日1次是在每月的第一天,每月1月)和转化为SAGA系统。
This function uses module Potential Incoming Solar Radiation from SAGA
此功能使用模块潜在的入射太阳辐射SAGA
