      <description>The ALD Equatorial Polar product data has been averaged spatially over a 1.0 degree by 1.0 degree grid above -80 and below 80 degrees. The ALD Equatorial Polar product data is 
      presented in a table corresponding to the 1.0 degree by 1.0 degree grid. There are 160 latitude bands and 360 longitude bands below 80 and above -80, thus 57600 grid cells. Each cell 
      corresponds to one row in the table. The first 360 rows in the table are the data for the 1.0 degree latitude band centered at 79.5 degrees north latitude, the second 720 rows are the data for 
      the band centered at 78.5 degrees north latitude, and so on. Within each band, longitude increases eastward from the cell centered at 0.50 degrees east longitude to the cell centered at 
      359.50 degrees east longitude. Averaged LEND Data products are composed of averaged normalized Counting rates and the associated timing, spatial and engineering information. The ALDs consists 
      of the cumulative background subtracted and normalized counts of neutrons at the nine LEND detectors averaged over the above defined.</description>
