AMF Deployment, Ganges Valley, India

Location: 29 21' 33.84" N, 79 27' 29.27" E

The AMF is operating at the ARIES Observatory in Nainital from June 2011 to March 2012.

In June 2011, the ARM Mobile Facility (AMF) began operations at the ARIES Observatory in Nainital for the Ganges Valley Aerosol Experiment (GVAX). The objective of GVAX is to obtain measurements of clouds, precipitation, and complex aerosols to study their impact on cloud formation and monsoon activity in the region.

This complex field study will use the AMF to measure radiative, cloud, convection, and aerosol characteristics over mainland India for a 10-month campaign. Most of the AMF instrumentation will be operated from the ARIES Observatory. A Beechcraft-20 aircraft, operated by collaborators from the Indian Institute of Science and the Indian Space Research Organization, will be deployed from February to April 2012. The resulting data set will capture pre-monsoon to post-monsoon conditions to establish a comprehensive baseline for advancements in the study of the effects of atmospheric conditions of the Ganges Valley.

The GVAX campaign is being conducted under an existing Science and Technology Cooperation Agreement between The Government of the United States of America and The Government of the Republic of India.
