用ncl_filedump命令输出如下: forecast_time0为64
Variable: f
Type: file
filename: Z_NWGD_C_BABJ_20200902032137_P_RFFC_SCMOC-TMP_202009020800_24003
path: Z_NWGD_C_BABJ_20200902032137_P_RFFC_SCMOC-TMP_202009020800_24003.GRB2
file global attributes:

用Panoply软件读取,time是80 实际数据也是80才对
netcdf file:/C:/Users/administrator/Desktop/Z_NWGD_C_BABJ_20200902032137_P_RFFC_SCMOC-TMP_202009020800_24003.GRB2 { dimensions: lon = 1401; lat = 1201; time = 80; height_above_ground = 1; variables: int LatLon_Projection; :grid_mapping_name = "latitude_longitude"; :earth_radius = 6371229.0; // double float lat(lat=1201); :units = "degrees_north"; float lon(lon=1401); :units = "degrees_east"; double reftime; :units = "Hour since 2020-09-02T08:00:00Z"; :standard_name = "forecast_reference_time"; :long_name = "GRIB reference time"; :calendar = "proleptic_gregorian"; double time(time=80); :units = "Hour since 2020-09-02T08:00:00Z"; :standard_name = "time"; :long_name = "GRIB forecast or observation time"; :calendar = "proleptic_gregorian";
ncl读取出来的数据和实际的预报时次差16个,请问大家又遇到过这个问题吗
