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

1^st 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:
1. Uncertainty regarding AR climatology
2. The relationship between ARs and precipitation
3. 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
