How to run a first inversion# Tutorials on how to run a first inversion with various models driven by the CIF: First inversion with the toy Gaussian model Prerequisites Step 1 — Prepare the observation vector Step 2 — Set up the YAML configuration Step 3 — Run the inversion Step 4 — Explore the outputs Comparing inversion algorithms with the toy Gaussian model Overview 4D-VAR with M1QN3 4D-VAR with congrad Analytical inversion EnSRF (Ensemble Square-Root Filter) Spatial resolution of the control vector First inversion with CHIMERE Prepare the executable Section for pyCIF parameters Mode (mode) Unchanged paragraphs Data vector (datavect) Run the simulation Check and post-process the results
