NASA/NOAA MOU Annex

Fall AGU 2018 Abstract

NOAA SWPC / CCMC Partnership to Validate Heliospheric Models
CCMC: M. Leila Mays, Peter Macneice, Aleksandre Taktakishvili,
NOAA/SWPC: Eric Adamson, Vic Pizzo, Doug Biesecker

In 2017 NOAA SWPC and CCMC started a new project under an annex to a memorandum of understanding between NASA and NOAA. The purpose of this project is to assess improvements in CME arrival time forecasts at Earth using the Air Force Data Assimilative Photospheric Flux Transport (ADAPT) model driven by data from the Global Oscillation Network Group (GONG) ground observatories. These outputs are then fed into the coupled Wang-Sheeley-Arge (WSA) - ENLIL model and then compared to the current operational version of WSA-ENLIL (without ADAPT). The project is performed in close collaboration with model developers.

SWPC has selected a set of 33 historical events over the period of three years from 2012-2014. The overall two-year project consists of multiple simulation validation studies for the entire event set: (a) benchmark (current operational version) (b) time-dependent sequence of GONG maps driving WSA-ENLIL (c) single test simulation of a time-dependent sequence of GONG maps driving ADAPT-WSA-ENLIL (d) single GONG map driving ADAPT-WSA-ENLIL (e) time-dependent sequence of GONG maps driving ADAPT-WSA-ENLIL. After each stage, the performance of the new simulation results will be compared to the benchmark (stage a) and to other previous stages. Here we present preliminary validation results for stages (a)-(c) that test the performance when using time-dependent backgrounds.

Discussion Notes


Events

• Initially NOAA/SWPC selected a set of 33 historical events and 36 CME input parameters have been provided (3 events contain 2 CMEs) for the period of 2012-2014. Later, NOAA/SWPC added 5 more events in 2017-2019 to include events that can use more recent zero point corrected synoptic maps. All 38 events are available to view from CCMC's public DONKI database via an API in text or JSON format (if your are prompted for a password, please click the link again and it will bypass the login screen).
• Replication event subset for which input/output is available [TXT]
