害 突然就搞懂了
begin
filename = "iceage_nh_12.5km_19840101_19841231_v4.1.nc"
f = addfile(filename, "r")
ice_age0 = f->age_of_sea_ice(0,:,:) ;1984年第一周的数据
ice_age = byte2flt(ice_age0)
ice_age@lat2d = f->latitude ;加上这两句就可以了
ice_age@lon2d = f->longitude
wks = gsn_open_wks("png","nic_ims")
res = True
res@cnFillOn = True
res@cnLinesOn = False
res@cnLineLabelsOn = False
res@gsnPolar = "NH"
res@mpMinLatF = 50
plot = gsn_csm_contour_map_polar(wks,ice_age,res)
