DA instance with multiple obs types

Hi,

 

we are trying to run a data assimilation in LIS with

 

Number of data assimilation instances:               1

Data assimilation number of observation types:       2

 

After trying and looking into the code for a while we have a basic question:

Are multiple obs for a single DA instance currently supported?

 

We encounter some issues that seem to be related to a commented line (line 340) in

https://github.com/NASA-LIS/LISF/blob/master/lis/core/LIS_DAobservationsMod.F90

 

       do k=1,LIS_rc%ndas

! odeltas(k) = LIS_rc%obs_ngrid(k)*LIS_rc%nobtypes(k)

          odeltas(k) = LIS_rc%obs_ngrid(k)

       enddo

 

which might indicate that two observation types are currently not supported ?!?

 

thanks!

Michel
