IASOA Radiation and Clouds Working Group

 

Sept. 20, 2017

 

Attendees: Chris Cox, Taneil Uttal, Allison McComiskey, Diane Stanitski, Gijs de Boer, Chuck Long, Matt Shupe, Sandy Starkweather, Nate Miller, Ulas Im, Joseph Sedlar, Alessio Bozzo, Manfred Wendisch, Kim Strong, Lei Liu, Jeff Key, Sara Morris

 

Introduction of group members, group title/focus now includes “clouds”. (Uttal, all)

Uttal made the comment that because this group has now been expanded to be radiation and clouds that it expected that the group will be developing new research motivators and plans.  This meeting was a brief update of some of the activities that were pursued during the Radiation only Working Group.

 

Update on D-ICE including objectives, timeline, example data, links to website and blog, website tour, and acknowledgements. D-ICE is a year long program that is assessing the ability of ventilation technologies to mitigate icing problems for Arctic radiometers. (Cox)

Update on Summit: The radiometers were taken from Summit to Boulder and calibrated at ESRL in this summer then returned. Data flow is currently coming through GMD with a few bugs being addressed. The tracker is currently (Sept 2017) at GMD being refurbished and Arctic-hardened, to be sent back to Summit in the spring. There are currently 2 years of funding remaining for this station. NOAA is open to maintaining the data passed this time frame if funding is available. GMD would like to re-propose Summit as a BSRN station at the 15th BSRN Workshop in Boulder, July 2018. (McComiskey)

 

Progress on radiation paper: No significant updates, but Cox would like to make this a priority. This paper will focus on a pan-Arctic survey of forcing derived from broad-band radiometers (Cox)

 

Progress on Barrow snow paper: Paper now in-press. An update on the 2017 (very) late melt was provided, as well as a report on the consistency of this anomaly with the circulation patterns described in the paper. There are plans to expand analysis and there is now more scientific motivation than ever to produce a regional climate index product. We are currently assessing whether this motivation is well-aligned with the user side; i.e. assessing the utility of such a product within the forecast and stakeholder community. Sandy provided some suggestions for people and organizations to reach out to. (Cox)

 

Kim Strong and Lei Liu called in and expressed interest in usage of several years of AERI data from the Eureka station for investigating cloud issues. There was some brief discussion of the usability of the broad-band radiation data from Eureka.

 

Priorities for upcoming year:

-Lei Lou is working on a post-doctoral research plan centered around the E-AERI at Eureka and the now 10+ year record of AERI data at that site.

-ALBSA index

-CRF paper

 

Action Items:

  • Begin email discussions with group members to assemble ideas/priorities for the upcoming year (Cox, Uttal)
