Hello
I write message first time.
If I want to compare trmm satellite data with ground point data,
I used to this line.

geo(0,207,2985) : trmm latitute
geo(1,*,*) : trmm longitute
lat : ground location(latitute)
lon : ground location(longitute)
rain : automatic weather system rainfall data
highf(0,207,2985) : trmm brightness temperature data

for i=0,207 do begin
for j=1200,1700 do begin
for k=0,di(0)-1 do begin

if geo(0,i,j) gt lat(k)-0.04 and geo(0,i,j) lt lat(k)+0.04 and $
geo(1,i,j) gt lon(k)-0.04 and geo(1,i,j) lt lon(k)+0.04 then begin
printf,lun3,loc(k),lon(k),lat(k),rain1(k),rain(k),highf(0,i, j)
endif

endfor
endfor
endfor

When I caculate 26 trmm data, I wait almost 2hour.
How can I change this program?
Help me.
