Hi guys!

My specific question is the same as the title of this post: does the ERA5-provided parameter, "mean temperature tendency due to parametrisations (paramId 235005) mean the total diabatic heating", which ought to be comprised of long (paramId 235001)+short (paramId 235002) wave radiational heating, latent heating, and the vertical mixing? 

Another question is about the date and time specification. As shown in the following picture, when downloading this parameter, I've chosen the time of 06 and 18, and the step of 0. Given that this data type is forecast (termed as 'fc' in the MARS request), I am quite uncertain whether the data (step=0) I downloaded represent the analysis data per se, whereby the daily mean can be calculated by averaging the value at 06 and 08?

Thanks,

JC Lee
