Research direction
Start by reviewing the global-workflow develop branch and the existing P1 approach, then trace how BUFR converters, IODA files, and JEDI fit into the proposed P2 cycle. Done means the listed deliverables are demonstrated: atmosphere-only 3DVar cycling, direct BUFR ingestion, and a moderate-resolution near-real-time run on an RDHPCS platform.
Written by the indexing model from the issue text.
Description
Demonstration of an initial end to end system at moderate resolution of an atmosphere-only cycling global model (prototype P2) in the global-workflow. Rather than leveraging GSI for observation preprocessing as done in prototype P1, this will use BUFR files as input to converters that write out IODA formatted files for use by JEDI. The analysis would be 3DVar only and this prototype would not include any ensemble component. This will demonstrate the first capability for a self-sufficient cycling system without any legacy code in the critical path.
Deliverables
Capability in NCEP’s global-workflow develop branch to cycle a moderate resolution atmosphere-only 3DVar system
Ability to process BUFR files directly in the workflow as ingest to JEDI
Moderate resolution near real time parallel cycling system running on a NOAA RDHPCS platform that produces short term forecasts for demonstration purposes
