Here is a link to the cdump and pardump outputs. ... 438gRlTlPO

The equation I use to calculate the area of the grid cell is
dLat * dLon * COS(lat1 / 57.2957795130823) * 111198.41730306273 ** 2.

Where dLat and dLon are the distance for a grid cell in degrees.
Lat1 is cornerLat + dLat * latIndex

I have confirmed its accuracy by using the snapshot mass concentration, which matches exactly to the PARDUMP mass.
The problem is the average concentration request is greater than the initial mass.
