运行Point2Grid

  1. 先使用ASCII2NC，转化为NetCDF格式

  2. 运行PointsGrid

    例如：制作能见度格点分析场

    $ ~/METplus-3.0.1/build_components/bin/point2grid 2020050200.vis.nc rap.t21z.wrfprsf27.grib 2020050200.vis.grid.nc -field 'name="VIS"; level="(*,*)";' -v 2

    例如：制作降水格点分析场

    $ ~/METplus-3.0.2/build_components/bin/point2grid rnwst.ascii.2019052700_acc24.nc rap.t21z.wrfprsf12.grib2 rnwst.ascii.2019052700_acc24.grib.nc -field 'name="APCP"; level="(*,*)";' -v 2
