International Workshop for First Phase of GEWEX/GASS ILSTSS2S Initiative and TPEMIP

Dates: 8-9 December 2018
Location: Washington Marriott at Metro Center, Washington, DC, USA
Abstract Submission Deadline: 15 November 2018
By Invitation Only

This will be the kick off workshop for the “Impact of initialized land temperature and snowpack on sub-seasonal to seasonal prediction” (ILSTSS2S) and “Third Pole Experiment Multi-Model Intercomparison” (TPEMIP). The ILSTSS2S aims to explore the impact of the initialization of large scale land surface temperature/subsurface temperature (LST/SUBT) and snow pack, including the aerosol in snow, in climate models on the S2S prediction over different regions. The ILSTSS2S is intended to be a joint project between GASS and other international programs. The focus of its first phase will be the impact of the Tibetan Plateau land condition on the East, South, and Central Asian S2S prediction, especially summer drought/flood, and will be jointly supported by the TPEMIP, which particularly focus on the impact of land conditions in Third Pole area and Earth System models’ performance over the Third Pole and surrounding areas.

Participation is limited to invitees only.
