The CNR-ISAC 3DVar software is a general purpose 3DVar that can be used for research
purposes, for teaching and for operations. The software is able to assimilate the following types of
data: radio soundings, atmospheric motion vectors (AMV), radar reflectivity (with two different
methods), ASCAT (Advanced Scatterometer) surface winds, WIVERN (WInd VElocity Radar
Nephoscope) winds, lightning, GNSS-ZTD (Global Navigation Satellite System - Zenith
Tropospheric Delay), and rain rates in convective environments.
The 3DVar software of CNR-ISAC is organised in two main components with executables installed
in two different directories: w3dvar_main.exe installed in the folder w3dvar_par, and the
software w3dvar_node.exe installed in the folder w3dvar_par_node.

We provide the patches for using the 3DVar code with WRF model version 4.1 for the thermodynamical variables: temperature, water vapor mixing ratio and rain mixing ratio.
WRF_patches software downloadWe provide few routines in Interactive Data Lanuguade (IDL) for computing the length -scales of the horizontal components of the background error matrix for the zonal and meridional wind components, for the temperature and for the mixing ratio of the water vapour. We also provide an example for the computation of the background error matrix in the vertical direction.

This software was partially realized in the framework or the project AEROMET (AEROspatial data assimilation for METeorological weather prediction) - PROT. A0375- 2020-36588- Avviso Pubblico “Gruppi di ricerca 2020” - POR FESR Lazio 2014-2020
