就是WPS那步，你选不要湖泊的陆地覆盖

是修改 METGRID.TBL 这个文件的控制内容吗？这是官网上找到的类似的问题
The issue may be in how the metgrid program is interpolating the skin temperature field from a grid that is essentially identical to the WRF model domain defined by geogrid. In the v4.1 METGRID.TBL file, the entry for SKINTEMP is as follows:
CODE: SELECT ALL


========================================
name=SKINTEMP
mpas_name=skintemp
        interp_option=sixteen_pt+four_pt+wt_average_4pt+wt_average_16pt+search
        masked=both
        interp_land_mask  = LANDSEA(1)
        interp_water_mask = LANDSEA(0)
        fill_missing=0.
========================================
I'd need to look further into the metgrid code to see exactly how the interpolation methods handle a grid point that is not surrounded by valid data in the input (intermediate) dataset, but as a quick test, could you try modifying the SKINTEMP entry so that it looks like the following?
CODE: SELECT ALL


========================================
name=SKINTEMP
mpas_name=skintemp
        interp_option=nearest_neighbor
        fill_missing=-999.
========================================
You'll only need to re-run metgrid and check whether there are any -999 values in the interpolated skin temperature field in your met_em files. If there are no -999 values, that would tell us that it is the interpolation methods that are the cause of the zero values in the top row of the interpolated field, in which case we may be able to make the interpolation methods more robust (or just use a nearest-neighbor interpolation, since we know the source and target grids are identical).

是选择数据的时候，不是这个。你选modis的noLake的

是这个上面的静态数据？没看到 no lake 的。看说明都是必须使用的

除了with lake的都是没有的吧

去掉 with lake的静态数据？

版主，问题找到了，是下载gfs数据的问题。
我是选择nomads.ncep.noaa.gov/cgi-bin/filter_gfs_0p25.pl这种方式下载（全部level，全部variables ）的数，和ftp全球下载的数据差了几十个参数。
你知道这是为啥原因不？？

你这是过滤掉了一部分数据，建议全部下载

我就是全部level，var全部选择了的，发现还是有差距
