Detailed Description

Land IAU (Incremental Analysis Update) module, for the NoahMP soil/snow temperature (can be extended to include soil moisture)

reads settings from namelist file (which indicates if IAU increments are available or not)
reads in DA increments from GSI/JEDI DA at the start of (the DA) cycle
maps increments to FV3 grid points belonging to mpi process
interpolates temporally (with filter-weights if required by configuration)
updates states with the interpolated increments March, 2024: Tseganeh Z. Gichamo, (EMC) based on the FV3 IAU mod by Xi.Chen xi.ch.nosp@m.en@n.nosp@m.oaa.g.nosp@m.ov and Philip Pegion, PSL phili.nosp@m.p.pe.nosp@m.gion@.nosp@m.noaa.nosp@m..gov
