What is the exact format of sub-daily precipitation input file?

[kzha...@connect.hku.hk]

Dear SWAT experts,

I am new to ArcSWAT. So far, I have already successfully run and calibrated my model based on daily precipitation. But I encountered problems when I want to run it on hourly time step. I understand that I need to alter the pcp.pcp and basins.bsn files, and use SWAT executable to run instead of using ArcSWAT. However, I think it is possible to use ArcSWAT to get pcp.pcp. 

Can anyone tell me the exact format of sub-daily precipitation input (multiple stations) of ArcSWAT?

Below is the precipitation input of mine, please point out my fault and give me some guidance on this, I will be very grateful for it!

Best regards,

Kun
