数据格式:
variables:
double LON4(LON4 ;
LON4:long_name = "Longitude" ;
LON4:units = "degrees_east" ;
LON4:modulo = 360. ;
LON4:point_spacing = "even" ;
LON4:axis = "X" ;
double LAT4(LAT4) ;
LAT4:long_name = "Latitude" ;
LAT48:units = "degrees_north" ;
LAT4:point_spacing = "even" ;
LAT4:axis = "Y" ;
double TIME(TIME) ;
TIME:long_name = "Center time of the day" ;
TIME:units = "days since 1978-01-01 00:00:00" ;
TIME:time_origin = "01-JAN-1978 00:00:00" ;
TIME:axis = "T" ;
float SST(TIME, ZLEV, LAT4, LON4) ;
SST:_FillValue = -9.99f ;
SST:long_name = "Daily sea surface temperature" ;
SST:units = "degrees C" ;
data:
LON4 = 117.125, 117.375, 。。。。。。
LAT4 = 32.125, 32.375,。。。。。。
---------------------------------------------------------------------------------
NCL程序:
f = addfile("../data/SST_YS.nc", "r")
wks = gsn_open_wks("png","sst")
lon = f->LON4
lat = f->LAT4
sst = f->SST(0,0,:,:)
res = True
res@cnFillOn = True ; turn on color fill
res@cnLinesOn = False ; turn off the contour lines
res@cnLineLabelsOn = False ; turn the line labels off
res@cnInfoLabelOn = False
plot = gsn_csm_contour(wks,sst,res)
