<p style="margin-top:0;margin-bottom:0">I am working with the MCD19A2 data. In order to see the data extent for any given time period, 1 day, 1 month, 1 year, or any selected time period we need to assess.<span>I have a binning code to add the points, however
the points that are being added are the original AOD values in the hdf files.</span> In order to do this I am attempting to replace all data points in the hdf file to " 1 " if there is data that is within the range flag of the data file. I have attempted to
use the "where" function to make these replacements however I keep getting error bugs coming up. The portion of the script can be found below.</p>
