Hi Ivan, A simple, quick-and-dirty approach could be: t.rast.algebra basename=rain5 expression="rain5=rain + rain[-1] + rain[-2] + rain[-3] + rain[-4] + rain[-5]"
Temporal selection (start_date(rain)...) is probably more elegant... See: https://grass.osgeo.org/grass78/manuals/t.rast.algebra.html Cheers Stefan -----Original Message----- From: grass-user <[email protected]> On Behalf Of Ivan Marchesini Sent: tirsdag 9. august 2022 09:45 To: GRASS user list <[email protected]> Subject: [GRASS-user] temporal raster accumulation Dear GRASS users I'm a little bit confused about which can be the best module/tool to perform the following task I have a strd having a daily granularity. It contains total daily cumulated rainfall. I would like to create a new strd where, for each day, I have the cumulated rainfall in the antecedent 5 days can you kindly suggest which is the best tool (or combination of tools) to reach this aim? thank you very much Ivan _______________________________________________ grass-user mailing list [email protected] https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.osgeo.org%2Fmailman%2Flistinfo%2Fgrass-user&data=05%7C01%7CStefan.Blumentrath%40nina.no%7C1944c976bd1f4fb14a3608da79db2020%7C6cef373021314901831055b3abf02c73%7C0%7C0%7C637956279455240967%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=BKqu%2F7tSMq7jNp8BF6bKDc04rf4BpwElNSif3G12gc4%3D&reserved=0 _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
