You will use checkvar with a precision of 3 to create a
processing summary file and summary files for the two variables
latitude and longitude in the file latlon.dat.
Here is latlon.dat:
-47.303545 -176.161101 -0.928001 0.777265 -28.286662 35.591879 12.588231 149.408117 -83.223548 55.319598 54.118314 -136.940570 38.818812 91.411330 -34.577065 30.172129 27.331551 -155.233735 11.624981 -113.660611 77.652742 -79.177679 77.883119 -77.505502 -65.864879 -55.441896 -63.211962 134.124014 35.130219 -153.543091 29.918847 144.804390 -69.273601 38.875778 -63.002874 36.356024 35.086084 -21.643402 -12.966961 62.152266
To create the summary files, enter the following command:
checkvar latlon.dat -p 3 -o latlon.sum
A summary of processing information and the maximum and minimum for each variable are displayed on the screen. The following three files are created:
latlon.sum recaps processing activity, maximums and minimums
latitude.lst shows distribution of the latitude values in
latlon.dat
longitude.lst shows distribution of the longitude values
in latlon.dat.
