  • ComDA

    ComDA is to achieve a fast, easy-to-use, and multidisciplinary application-oriented assimilation platform. ComDA integrates many algorithms (including diverse Kalman and particle filters) and multiple models and observation operators (e.g., CoLM, SiB2 and AIEM, Q/h), and provides the general interfaces for accepting more operators. Using mixed-language programming and parallel computing technologies (OpenMP, MPI and CUDA), ComDA can assimilate various land surface variables and remote sensing observations. ComDA can be applied in multidisciplinary data assimilation studies.

  • Soil and Water Assessment Tool-Hydrological Data Assimililation System

    SWAT-HDAS is based on grid-based SWAT hydrological model, integrated Parallel Data Assimilation Framework(PDAF), applied for hydrological data assimilation studies.

    Its data assimilation algorithms include Kalman filters. SWAT-HDAS can assimilate remote sensed or ground based soil moisture, river discharge, snow water equivalent, etc.

    SWAT-HDAS was tested by GNU gfortran compiler. It will include Particle filter and Genetic Algorithm. Weather Research & Forecasting (WRF) climate model will also be integrated to achieve land-atomosphere coupling.
