Black carbon is "the second most important human emission in terms of its climate-forcing in the present-day atmosphere; only carbon dioxide is estimated to have a greater forcing." When BC is deposited on snow and ice, it darkens an otherwise bright surface. The darker surface may enhance the absorption of solar radiation resulting in an acceleration of snow and ice melting. In addition, BC particles suspended in the atmosphere absorb solar radiation and heat the surrounding air. Atmospheric BC can also alter cloud properties leading to changes in cloud amount and precipitation.
The 10th annual Polar Technology Conference will be hosted by the Pervasive Technology Institute of Indiana University, Bloomington, Indiana, on 15-17 April. Conference registration is now available. Abstracts for oral and/or poster presentations may also be submitted. Presentations in all technology fields are invited. Regular oral presentations and a poster session will be scheduled. Abstracts for oral presentations received after 14 March may not be considered. For further information, registration, or abstract submission, please go to the conference website.
This webinar will provide an update on the activity within discussion groups on www.arctichub.net and further opportunities to continue discussions relevant to long-term observing management and governance. A recap of recommendations received from the broad observing-minded community will be presented.The webinar will be available through Webex (details available at www.arctichub.net).
Please join fellow geographers, GIS specialists, environmental scientists, and other leaders for the latest in research and applications in geography, sustainability, and GIScience at the 2014 Annual Meeting of Association of American Geographers (AAG). The meeting will be held from April 8 to April 12, 2014, and will feature over 5,000 presentations, posters, workshops, and field trips by leading scholars, experts, and researchers.
Many sessions will be organized around special, featured themes including:
We are pleased to announce that on 7th – 11th April 2014 the Centre for Ice and Climate (University of Copenhagen) will be hosting a workshop on subglacial processes, focusing on the role of sediment and water.
The Arctic Science Summit Week (ASSW) is the annual gathering of international organizations engaged in supporting and facilitating Arctic research. Its purpose is to provide opportunities for international coordination, collaboration and cooperation in all fields of Arctic science and to combine science and management meetings.
The ASSW and AOS meetings are arranged during April 5-8 and April 9-11 in Helsinki. The conferences will be arranged in the facilities of the University of Helsinki and the Finnish Meteorological Institute located on the science campus Kumpula.
The APECS Workshop "Connecting Early Career Researchers and Community-Driven Research in the North" is part of the APECS Nordic Project "Bridging Polar Early Career Researchers and Indigenous Peoples in Nordic Countries" funded in part by the Nordic Council of Ministers (Norden). The workshop will bring together key stakeholders including mentors and experts and Early Career Researchers and Indigenous peoples, youth and local expert representatives among indigenous peoples, senior scientists, key representatives of international organizations and other media.
This workshop is dedicated to both snow hydrologists and researchers dealing with avalanche formation, as well as scientists from the remote sensing and glaciology communities aiming at retrieving snow water equivalents. The workshop will last 2 full days and is organized by SLF Davos and IUP Heidelberg. We expect the number of attendees to be rather small (30-50 people) so that there will be ample room for exchange and discussions. The goal is to gather specialists from renowned research institutions worldwide.
The Sea Ice Prediction Workshop will be held at National Center for Atmospheric Research (NCAR) on 1-2 April 2014 in Boulder, Colorado.
The workshop goal is to plan for the 2014 SEARCH Sea Ice Outlook (SIO) and to advance the science of sea ice prediction by coordinating experiments, defining and developing data sets for initialization and validation, creating new and better metrics for evaluation, and discussing stakeholder needs.
ARCUS is a nonprofit organization consisting of institutions organized and operated for educational, professional, or scientific purposes to advance arctic research and education.
