I would strongly recommend developing a new script that operates on each 100 row chunk of data, and that uses coordinate subscripting to put the data in the proper place in your final data array. One negative to this method is the possibility exists that multiple nearby data points get assigned to the same grid point, but this can be countered by setting your master array grid appropriately. An example:</div><div><br></div><div>; Untested! Review the code below.</div><div><div> yrStrt = 1920</div><div> yrLast = 2014</div></div><div><div> file_name = "Rain_estimate_2.5DegGrid.txt"</div><div> rain = asciiread(file_name, -1, "string")</div></div><div><br></div><div>lat = fspan(6.25,43.75,16)</div><div>lat@units = "degrees_north"</div><div>lat!0 = "lat"</div><div>lat&lat = lat</div><div><div>lon = fspan(-23.75, 11.25,15)</div><div>lon@units = "degrees_east"</div><div>lon!0 = "lon"</div><div>lon&lon = lon</div></div><div>time = yyyymm_time(yrStrt,yrLast,"integer")</div><div>mod_data = new((/(yrLast-yrStrt+1)*12,dimsizes(lat),dimsizes(lon)/),float,-999.) ;Set up master array that will be filled in. </div><div>mod_data!0 = "time"</div><div>mod_data&time = time</div><div>mod_data!1 = "lat"</div><div>mod_data&lat = lat</div><div>mod_data!2 = "lon"</div><div>mod_data&lon = lon</div><div><br></div><div>nrow = numAsciiRow("file_name")</div><div><br></div><div>do gg = 0,nrow-1,100 ; Run a do loop over each 100 row segment</div><div> temp = rain(gg:gg+99)</div><div> coords = str_split(temp(1)," ")</div><div> print(coords) ; examine results of text split</div><div> lat_coord = tofloat(coords(2))</div><div> lon_coord = tofloat(coords(5)) </div><div> do hh = 5,99 ; operate on rows 5-99 of temp </div><div> data = tofloat(str_split(temp(hh)," "))</div><div> mod_data({data(0)*100+1:data(0)*100+12},{lat_coord},{lon_coord}) = (/ data(1:) /)</div><div> delete(data)</div><div> end do</div><div> delete(temp)</div><div> print("Now done with lat="+lat_coord+", lon="+lon_coord) </div><div>end do</div><div><br></div><div>The above should at least get you going.
