O1-03: Toward a community consensus for metrics in solar physics and space weather

  • New team ! Outcome of the mini-ISWAT discussions at ESWW Coimbra, 2024

Goal

Why is it important:

To achieve transparency, accuracy and consistency for all modeling efforts, scoreboards, scientific research, publications within the community 

standardization of metrics for solar wind, CMEs, coronal holes, photospheric magnetic field map etc

Identification of the minimum combination of metrics that will provide the most complete evaluation for the phenomenon of interest

Reach a consensus on the metrics that should

*at least* be used for the assessment and evaluation of different space weather phenomena.

O1-03: Toward a community consensus for metrics in solar physics and space weather

  • Directly connected to the goals of other action teams:
    • H1-01: Solar wind validation
    • H1-03: Solar wind scoreboard
    • H2-01: CME arrival time/Scoreboard
    • S2-01: Coronal holes
    • S2-03: Global solar magnetic field maps
    • ….and many more!

​

Aim: Build strong cross-cluster collaborations to achieve the best for the community!

O1-03

First part

(PM2 Thursday)

O1-03

Second part

(Lively discussion Thursday)

Solar wind

Solar wind/Coronal holes/SEPs/CMEs

  • Introduction of well known applied solar wind metrics:
    • WSA PM metric
    • MSE, correlation coefficient
    • Binary metrics on HSS events
    • Sigma-method
    • Dynamic Time Warping

​

  • Discussion on strengths + weaknesses
  • (Try to) reach consensus on the subset of metrics that is *at least* sufficient to be employed for solar wind evaluation
  • Does the community want/need standardization of metrics?

​

  • Is it timely to discuss about it? If yes, for which solar/space/geo phenomena?

​

  • Summaries of what was discussed in previous sessions
