想用新的土地利用数据替换WRF中的旧土地利用数据,已经重新分类并且转为二进制,并且写好了index文件,修改后的土地利用数据是24类,但是跑完geogird后产生的d03依旧是21类,想问问是为什么。步骤一:已经修改GEOGRID.TBL,但是只修改了name=LANDUSEF,修改后为
name=LANDUSEF
priority=1
dest_type=categorical
z_dim_name=land_cat
dominant = LU_INDEX
landmask_water = lucc2015:16 # Calculate a landmask from this field
interp_option = lucc2015:nearest_neighbor
rel_path = lucc2015:lucc2015/
步骤二:修改了namelist.wps,修改后为
&geogrid
parent_id = 1, 1, 2,
parent_grid_ratio = 1, 3, 3,
i_parent_start = 1, 25, 64,
j_parent_start = 1, 24, 55,
e_we = 90, 136, 58,
e_sn = 90, 136, 58,
geog_data_res = ‘lucc2015’
dx = 9000,
dy = 9000,
map_proj = 'lambert',
ref_lat = 40.00,
ref_lon = 116.0,
truelat1 = 40.00,
truelat2 = 40.00,
stand_lon = 116.0,
geog_data_path = '/public1/home/sch10001/WRF/WPS_GEOG/'
/
想问问是哪里还没有修改好吗?这是我的index文件:
type=categorical
category_min=1
category_max=24
projection=regular_ll
dx=0.0117836266203959
dy=0.0117836266203959
known_x=1.0
known_y=1.0
known_lat=14.9967033487
known_lon=66.2922997248
wordsize=1
tile_x=6157
tile_y=3393
tile_z=1
units="category"
description="USGS 24-category land use categories"
mminlu="USGS"
missing_value=128
iswater=16
islake=-1
isice=24
isurban=1
row_order=top_bottom
谢谢!
