Irrigation area data

Netcdf used to generate Figure 1d in <b><i>The importance of irrigation for the accurate simulation of fog over northern India. </i></b>Values of 1 indicates irrigated and 0 indicates not irrigated in the netcdf. This is used to decide the area to increase soil moisture to saturation. The irrigated area is derived using the CCI land use data and a global irrigation water use dataset. A 1 is assigned to a grid point if it is identified as irrigated cropland in the CCI dataset and the irrigated water use for January is above 5 mm.本数据集为论文《灌溉对印度北部浓雾精准模拟的重要性》（*The importance of irrigation for the accurate simulation of fog over northern India*）中图1d的生成所用的NetCDF（网络通用数据格式）文件。该文件中，数值1代表灌溉区域，数值0代表非灌溉区域。本数据集用于划定需将土壤湿度提升至饱和状态的区域。灌溉区域通过CCI土地利用数据与全球灌溉用水数据集推导得到。若某网格点在CCI数据集中被识别为灌溉农田，且其1月灌溉用水量超过5毫米，则为该网格点赋值为1。
