I am attempting to re-grid MCD19A data from 1km grid size to a larger 20km or 25km grid size. I have a code that is partially running but have hit a snag on line 50 in the code. I am looking to use this re-gridding to fill in (interpolate) for the missing data
to make comparisons verses 3 ground-based measurement sites.<br>
