alicec,
Here is a link to the cdump and pardump outputs.
https://ftp.ornl.gov/filedownload?ftp=e ... 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.

Thanks,
Jordan
