Hello, A yearly allocation for the LCRC cluster has been requested with the following updated information: Submitter/PI: Rao Kotamarthi Project Name: WRF-CHEM-GVAX Division: EVS Project title: Weather and Aerosol forecast products for the Ganges Valley Aerosol Project Associated funding: DOE-BER Other Systems: NERSC Science: The Ganges valley region is one of the largest and most rapidly developing sections of the Indian subcontinent. Impacts of changes in precipitation patterns, temperature, and the flow of the snow-fed rivers could be immense. Recent satellite-based measurements have indicated that the upper Ganges valley has some of the highest persistently observed aerosol optical depth values. The aerosol layer covers a vast region, extending across the Indo-Gangetic Plain to the Bay of Bengal during the winter and early spring of each year. This is one of the few regions showing a trend toward increasing surface dimming and enhanced mid-tropospheric warming. The consequences of aerosols and associated pollution for surface insolation over the Ganges valley and monsoons in particular are not well understood. Our proposed field study will provide critical data to address these hypotheses and will contribute to developing better parameterizations for tropical clouds, convection, an d aerosol-cloud interactions. The primary science questions for the mission are as follows: (a) What are the sources and sinks of the aerosols comprising the aerosol cloud over this region and what effects does it have on clear-sky radiation fields, as well as on cloud micro- and macrophysical properties? What effect does the diurnal PBL cycle in the Ganges valley have on the atmospheric distribution of aerosols? (b) What effect do increasing aerosols in the Ganges Valley have on the ISM? What effect do aerosols have on shortwave radiative forcing, mid-tropospheric heating and convective activity over continental India? To achieve these science objectives an implementation has been devised in collaboration with scientists in India. The primary anchor facility for the project is the ARM mobile facility. A deployment starting in approximately June 2011 and lasting to April 2012 at the ARIES observatory located in Nainital is anticipated for AMF ground operations. During this one-year deployment of the AMF there will be an intensive periods, extending from February 1st, 2012 to April 1st 2012 (winter intensive). Project description: We continue to analyze the measurements from GVAX using 3-D regional scale model simulations. These modeling results of air pollution and meteorological fields will become one of the central ‘data’ products for the experiments archived at the ARM websites. The expectation is that there will be a significant number of scientists from around the world who will be interested in GVAX data. In addition, the 3-D model will be a test bed for high performance computing data storage and visualization. The project this year will use the resources to perform diagnostic simulations for the year 2011-2012 and explore the data and model comparison issues arising from the GVAX project.
