sptial distribution

Hi All,

I read data from ASC file. Then I define lat and lon and plot the data
over the global region, but the distribution is wrong. This error is
related to lat and lon of data I think. But I don't know how the lat and
lon associate to data coordinates correctly?

Thanks,

Chao

The part of script I used as follows:

spe_nbr = 48
lat_nbr = 46
lon_nbr = 72
data = asciiread("./annl_avg_emi95.dat" \
                      , (/lon_nbr,lat_nbr,spe_nbr/),"float")

;;;define lat and lon
lat = new ((/lat_nbr/), float)
lon = new ((/lon_nbr/), float)

do ilon=0,lon_nbr-1
lon(ilon) = -177.5+ilon*5.
end do

lat(0)=-89.0
lat(lat_nbr-1)=89.0
do ilat=1, lat_nbr-2
lat(ilat)=-86.00 + 4.*(ilat-1)
end do

.
.
.

plot(1) = gsn_csm_contour_map_ce(wks_id,data(;,;,0),res1)
