Sir,

Hope this email finds you well. The precipitation we obtain from RegCM model output is in kgm2s-1 . If we need to convert it to mm/day ,  the conventional method is multiplying the precipitation with 86400(24*60*60). But this method seems to over estimate the precipitation a lot . When the observation over the tropics is showing a maximum of 53 mm/day , the model output ranges upto 90mm/day . Is any other method possible? Awaiting your response.

Thank you.
