IMERG dataset error

[MariRiba]

Hi
I am using GPM IMERG dataset version V07B for precipitation forcing. When I am running the LIS I am getting an error:

[INFO] Reading HDF5 IMERG precipitation data from /scratch2/mari/lisf/IMERG/201601/3B-HHR.MS.MRG.3IMERG.20160102-S000000-E002959.0000.V07B.HDF5
Error opening IMERG dataset/Grid/precipitationCal
[WARN] Error reading IMERG file /scratch2/mari/lisf/IMERG/201601/3B-HHR.MS.MRG.3IMERG.20160102-S000000-E002959.0000.V07B.HDF5
[INFO] LIS cycle time: 01/02/2016 00:30:00

How can I correct it ?

the lis.config file is :
lis.config_imerg.txt

@MariRiba:

The GPM IMERG reader in LIS should have been updated in the "master" branch back in Aug-2023, with support for the IMERG V7 final files.

You may want to check which latest version that you have checked out of LISF, and if it is prior to Aug-2023.

Dear @MariRiba,

This issue is caused because the older IMERG versions (before V7) had precipitation variable in the name of 'precipitationCal' (which is a combination of both IR & Microwave), but in the new IMERG versions (V07), the precipitation variable is named as 'precipitation'.

This has been resolved in the latest available version LISF - 7.5.0. If using 7.4.x or anything lesser, then edit the code in the 'read_IMERG.F90' file located at 'lis/metforcing/imerg' as below,

Orginal command line: character(len=40) :: dsetname='/Grid/precipitationCal'
New command line: character(len=40) :: dsetname='/Grid/precipitation'

Hope this helps! :)
