ARTMIP One-Month Trial Run Telecon

Date: 22 September 2017

Goals

  • Review 1-month proof of concept catalogues
  • Adjust experimental design, if necessary
  • Adjust metrics, if necessary
  • Discuss contributions for experimental design paper

Outcomes

  • 15 groups participated in 1-month trial, along with two “Human” controls, i.e. 2 participants counted ARs “by eye” for both Western U.S. and Europe
  • Discussed spread in intensity, frequency, and duration in catalogues
  • Discussed refinement of metrics for both climatologies and case studies
  • Set final requirements and dates for full catalogues, and contributions for experimental design paper

1st ARTMIP Workshop

Date: 10 - 11 May 2017

Location: Scripps Institute of Oceanography

Goals

  • To create ARTMIP framework
  • Choose common data set for initial catalogues
  • Gain community input on key science questions
  • Gain community input on AR metrics for ARTMIP

Outcomes

  • Tier structure established
  • Chose MERRA-2 1980-2017 for Tier 1 catalogues
  • Designed a 1-month “proof of concept” trial run to work out bugs with Tier 1 design. February 2017 was chosen due to high AR frequency in PNW during this time period
  • Chose CAM5 25km LLBL climate change runs for Tier 2 climate catalogues
  • Key science questions are related to:
    • Uncertainty regarding AR climatology
    • The relationship between ARs and precipitation
    • How these may be altered under future climate change scenarios
  • Fundamental metrics include AR frequency, duration, intensity, and the climatology of these quantities
  • Co-chairs will lead two papers:
    • Outlining experimental design
    • Scientific results from Tier 1
