GOOD MORNING

The output that RegCM generates are ATM, SRF, RAD and STS. The STS file generates daily output data while the other files generate 3-hr interval data.

My query is:-

1. Is the daily precipitation data from STS file is cumulative of 3-hr interval data from SRF file ?

2. The output of precipitation,from STS file, obtained from downscaling "GFDL-ESM2M" global data has the unit (mm/s) if we use 

'q file' command in GrADS. So if I want the data in mm/day should I multiply the data with 86400 ?
