First ARM Summer Workshop
National Weather Center in Norman, Oklahoma
13-24 July 2015

In an effort to promote the training of the next generation atmospheric scientists, the first ever Atmospheric Radiation Measurement (ARM) Summer Workshop on observations and modeling of aerosol, clouds, and precipitation will take place this summer July 13-24, 2015. Sponsored by the ARM Climate Research Facility, this workshop will cater to graduate and postdoctoral students interested in observations and modeling of aerosol, clouds, and precipitation processes.

The summer workshop will provide theoretical and practical training on instruments from the Southern Great Plains site and will encourage innovative methods for using ARM facilities to address complex scientific inquiries. The summer workshop will be held at the National Weather Center in Norman, Oklahoma.

Daily activities will include two keynote lectures and discussion, followed by four to six hour sessions of group activities. The working groups will explore the following themes:

  • Aerosols and cloud condensation nuclei
  • Boundary layer structure
  • Cloud birth and fraction
  • Cloud properties
  • Cloud to precipitation transitioning
  • Precipitation properties
  • Models' ability to capture clouds

Please send your application (i.e., a motivation letter, one recommendation letter, and curriculum vitae [CV]) in a single PDF to Jackie Marshall at jackie.marshall@pnnl.gov. Travel and accommodation expenses will be covered for the selected participants by the ARM Facility.

Alpine Summer School - Course XXIII
Land-atmosphere interactions: coupling between the energy, water and carbon cycles

Valsavarenche, Valle d'Aosta, Italy
21 June - 2 July, 2015

The land surface and the overlying atmosphere are tightly coupled systems. These feedbacks are regulated through the interface, the planetary boundary layer in which intense turbulence occurs. Land-atmosphere interactions are important sources of seasonal climate predictability in several parts of the world. Soil moisture and vegetation are key parameters influencing land-atmosphere interactions in the climate system by modifying the surface energy, moisture and carbon fluxes, and boundary conditions for the boundary layer. Because soil moisture, vegetation, turbulence (boundary layer and moist convection) organize on many different temporal and spatial scales, the study of land-atmosphere interactions has been notoriously difficult. The study of land-atmosphere interactions encompass a wide range of disciplines, which will be discussed during the summer school from soil science, surface hydrology, hydrometeorology, plant physiology, turbulence, convection and atmosphere circulation. As such, there is no single type of land-atmosphere interactions but a wide variety of cases embedded within the larger-scale general circulation.
There have been considerable developments in recent years on the subject so that an up-to-date summer school presenting a quantitative approach outlining physical principles, and the mathematical basis of land-atmosphere interactions is required. A book, following up on this summer school and using the lecture materials, will be published by Wiley in 2016.

Courses
The courses will cover surface energy, carbon and water balances, soil-plant-atmosphere continuum and plant physiology (motion through the soil, roots, xylem and stomata), surface and boundary layer turbulence, feedback analysis, heterogeneity, shallow and deep convection, extremes, annual and cold season coupling between radiation-turbulence and precipitation, metrics in land-stmohspere interactions, modeling, and remote sensing observations.
