[RegCNET] Total precipitation

[zhangdf at cma.gov.cn]

Hi Beatrice,

If your output frequency is 6hr, 

For Jan, Mar, May, Jury, Agu, Oct, Dec: precipitation of a month=(ave(tpr,t=1,t=124))*31

For Feb: precipitation of a month=(ave(tpr,t=1,t=112 or 116))*28 (or 29)


For others:  precipitation of a month=(ave(tpr,t=1,t=120))*30

Best regards,
Zhang

  Dear All,

  In files of ATM and SRF, precipitation is given in units of mm/day. Is it then the rate or total amount of one time step?

  What should I do if I want to have total precipitation of a month (in units of mm).

  Many thanks by advance for your reply.

  With best regards

  Beatrice
