Level A Pan Europe Solar Index For Estimation Of Potential Evaporation November

Solar Index for estimation of Potential evaporation November. Solar Index (SI) maps are input needed for spatial estimation of potential evaporation by using modified Blaney Criddle method (Schrödter 1985, Parajka et al., 2003). SI maps are available for each month. SI maps are available for each month. Spatial resolution: 1km2. Solar Index maps (SI_xxx) for estimation of potential evaporation by using modified Blaney Criddle method. Maps are available for each month (xxx). Format ArcGIS ASCII grid. Maps are estimated from GTOPO30 DEM. Coordinates: geographical. SI index is estimated in GIS GRASS (r.sun module).用于潜在蒸发量估算的十一月太阳指数（Solar Index, SI）。太阳指数（SI）栅格是采用修正布莱尼-克里德尔法（modified Blaney Criddle method，Schrödter, 1985；Parajka等, 2003）开展潜在蒸发量空间估算的必备输入数据。该太阳指数栅格集覆盖全年所有月份，空间分辨率为1平方千米。用于修正布莱尼-克里德尔法潜在蒸发量估算的太阳指数栅格命名格式为SI_xxx，其中xxx为月份代号。数据格式为ArcGIS ASCII栅格，基于GTOPO30数字高程模型（DEM）生成，采用地理坐标系，通过地理信息系统软件GRASS的r.sun模块计算得到。
