Hello,
As per the definition of the 'mean total precipitation rate', it is calculated as sum of the rates due to large-scale precipitation and convective precipitation. However, when I calculated the sum of convective rain rate, mean convective snowfall rate, large scale rain rate and large scale snowfall rate over a grid for the same time step, the sum was different (1.29 vs 1.26; slight difference) from the 'mean total precipitation rate'. Could someone please help me understand what is causing this difference to appear?
Thanks
