fnl画地面形势图，气压、风速的选择

悠然一梦123

用fnl数据画地面形势图，想知道风速应该选择下面哪个形式的，求告知。

float UGRD_P0_L102_GLL0(lv_AMSL1, lat_0, lon_0) ; lv_AMSL1=3代表什么，三个值大小是多少？

UGRD_P0_L102_GLL0:initial_time = "04/23/2014 (00:00)" ;

UGRD_P0_L102_GLL0:forecast_time_units = "hours" ;

UGRD_P0_L102_GLL0:forecast_time = 0 ;

UGRD_P0_L102_GLL0:level_type = "Specific altitude above mean sea level (m)" ;

float UGRD_P0_L103_GLL0(lat_0, lon_0) ;

UGRD_P0_L103_GLL0:initial_time = "04/23/2014 (00:00)" ;

UGRD_P0_L103_GLL0:forecast_time_units = "hours" ;

UGRD_P0_L103_GLL0:forecast_time = 0 ;

UGRD_P0_L103_GLL0:level = 10.f ;

UGRD_P0_L103_GLL0:level_type = "Specified height level above ground (m)" ;

float UGRD_P0_2L108_GLL0(lat_0, lon_0) ;

UGRD_P0_2L108_GLL0:initial_time = "04/23/2014 (00:00)" ;

UGRD_P0_2L108_GLL0:forecast_time_units = "hours" ;

UGRD_P0_2L108_GLL0:forecast_time = 0 ;

UGRD_P0_2L108_GLL0:level = 3000.f, 0.f ;

UGRD_P0_2L108_GLL0:level_type = "Level at specified pressure difference from ground to level (Pa)" ;

气压是这个形式的吗

float PRES_P0_L101_GLL0(lat_0, lon_0) ;

PRES_P0_L101_GLL0:initial_time = "04/23/2014 (00:00)" ;

PRES_P0_L101_GLL0:forecast_time_units = "hours" ;

PRES_P0_L101_GLL0:forecast_time = 0 ;

PRES_P0_L101_GLL0:level = 0.f ;

PRES_P0_L101_GLL0:level_type = "Mean sea level (Pa)" ;

没人理我吗。求大神解决啊

二爷名声在外

你看文件的最后，有这几个的说明
