*Dear Olaguera,*

*'reinit'****Open your netcdf file 'sdfopen

Set the longitudes and latitudes of you stations e.g in East
Africalon.1=36.4lon.2=36lon.3=36.8lon.4=35.3lat.1=-0.4lat.2=1.3lat.3=-1.3lat.4=0.5lat.5=-0.5***set
names of stations corresponding to your
coordinatessta.1=Kenyasta.2=Ugandasta.3=Tanzaniasta.4=Rwandasta.5=Burundii=1while(i<=5)ln=lon.ilt=lat.istn=sta.i'set
lon 'ln'set lat 'lt'set t 1'****** pr is your variable***define where your
values will be extracted to e.g****** %g 1 1 will extract your values in
one continues column'fprintf pr
C:\Users\Joshua\Documents\precipitation-data\'stn.txt %g 1
