I have downloaded two types of half-hourly and three-hourly satellite precipitation data for the study area from Gportal. Now I have a question about those data, please help in this regard.
GPM_3IMERGHH half-hourly NetCDF file
3B-HHR.MS.MRG.3IMERG.20170322-S000000-E002959.0000.V06B.HDF5.SUB.nc4
Question 1: Does this file cover the amount of precipitation from 23:45 UTC of the previous day to 00:15 UTC of the current day or it represents the period from 23:30 UTC of the previous day to 00:00 UTC of the current day?
GPM_3IMERGHH half-hourly NetCDF file
3B-HHR.MS.MRG.3IMERG.20170321-S103000-E105959.0630.V06B.HDF5.SUB
Question 2: Does this file cover the amount of precipitation from 10:00 UTC of the current day to 10:30 UTC of the current day or it represents the period from 10:15 UTC of the current day to 10:45 UTC of the current day?
TRMM_3B42RT three-hourly NetCDF file
3B42.20170302.00.7.HDF.nc4
Question 3: Does this file cover the amount of precipitation from 22:30 UTC of the previous day to 01:30 UTC of the current day or it represents the period from 21:00 UTC of the previous day to 00:00 UTC of the current day?
GSMAP 1-hourly HDF file
GPMMRG_MAP_1703021800_H_L3S_MCH_04C.h5
Question 4: Does this file cover the amount of precipitation from 17:00 UTC of the current day to 18:00 UTC of the current day or it represents the period from 17:30 UTC of the current day to 18:30 UTC of the current day?
