OceanVar2
OceanVar2, developed at CMCC, is an open-source state-of-the-art variational ocean data assimilation framework. 
OceanVar2 is used to study the ocean across a range of scales, from global to local and short-term to multi-decadal. Additionally, OceanVar2 provides initial conditions for short-range to seasonal forecasts.
OceanVar was first introduced by Dobricic and Pinardi (2008) and is based on a three-dimensional variational method, formulated in its classical incremental variant. OceanVar2 features a modular design that allows for flexibility in incorporating diverse data sources and error covariance representations. It supports the assimilation of in-situ ocean measurements of temperature and salinity, as well as remotely sensed data, including altimetry, and sea surface temperature and salinity, from a variety of datasets depending on the specific application.
OceanVar2 decomposes the background error covariance matrix into physically based linear operators, allowing for individual analysis of specific error components. A key feature of OceanVar2 is its ability to represent error correlations between temperature, salinity, and sea level anomalies (the sea level operator). OceanVar2 offers the flexibility of using either a dynamic height or a barotropic model for closed domains, or EOF-based correlations. Horizontal error correlations are modeled with a diffusive operator, replacing the previous recursive filter. Furthermore, the OceanVar2 code has been extensively revised into a unified, consistent, and fully parallelized framework, integrating past developments.
