Thank you. You're right, int8 isn't enough. I tried to use int15 and int18.
It gives me the following compiling error (both gfortran and ifortran).
-------------------------------------------------------------------------------------------------
In file test2.f90:69
CALL h5dread_f(dset_id,nat_type_id,data_out,data_dims,error)
1
Error: There is no specific subroutine for the generic 'h5dread_f' at (1)
---------------------------------------------------------------------------------------------------
Thanks,
Denis

int8 = selected_int_kind(8) (i.e int range 10^8) will not be big
enough to hold the numbers you are trying to read, try
selected_int_kind(15) which should give you an 8 byte integer.

Hello,
I ran into a problem reading H5T_STD_I64BE data using f90.
Following is a part of a routine code.
-------------------------------------------------------------------------------------
INTEGER, parameter:: int8 = selected_int_kind(8)
INTEGER(kind=int8), DIMENSION(:), ALLOCATABLE :: data_out
ALLOCATE(data_out(data_dims(1)))
CALL h5dread_f(dset_id,nat_type_id,data_out,dims,error)
...
--------------------------------------------------------------------------------------
Data set I'm trying to read looks like this:
HDF5 "GMODO_npp_d20100906_t2110510.h5" {
DATASET "/All_Data/VIIRS-MOD-GEO_All/MidTime" {
DATATYPE H5T_STD_I64BE
DATASPACE SIMPLE { ( 48 ) / ( H5S_UNLIMITED ) }
DATA {
(0): 1662498685374717, 1662498687161083, 1662498688947446,
(3): 1662498690733806, 1662498692520176, 1662498694306565,
...
--------------------------------------------------------------------------------------
I think the problem I have is a data type. I also tried to read as =>
CALL h5dread_f(dset_id,H5T_NATIVE_INTEGER,data_out,dims,error)
(I know it supports only 32-bit, but I didn't find anything for 64-bit.)
The result is always the same it gives me some weird numbers.
What data type should I use in Fortran 90?
Thanks,
Denis
