[gradsusr] Accuumulated precipitation

[Vladimir Meerson]

Dear GrADS users,


I have set of grib2 rainfall accumulation files from UKMET:

   (A) for times 1 ... 132 - 1-hour accumulation in each file

   (B) for times 135 - 168 - 3 hours accumulation in each file

My goal is to draw 6-hour accumulation graph (the sum of every 6 consecutive values for (A) and the sum of every 2 consecutive values for (B) - finally 4 points for each day).

How can I do this?


Thank you for your help.


Vladimir
