Atmospheric Lidar for Validation, Interagency Collaboration and Education
ALVICE (Atmospheric Lidar for Validation, Interagency Collaboration and Education) is a ground based mobile lidar that is a roving transfer standard within the Network for the Detection for Atmospheric Composition Change (NDACC). The lidar measurements are water vapor mixing ratio, aerosol backscatter, extinction, depolarization, cloud liquid and ice water and rotational Raman temperature measurements. In addition to these lidar-based measurements additional equipment is carried in the trailer to provide balloon borne measurements (Vaisala RS-92 and Cryogenic Frostpoint hygrometer), surface reference measurements of pressure, temperature and RH as well as total column water using GPS.
This project, referred to as 'HIMALA', studies climate impacts on glaciers in the Himalaya region. It was created in response to the 2008 NASA Decisions Support request for proposals. The overarching purpose of the Applied Sciences Program is to discover and demonstrate innovative applications of NASA Earth science research products and to maximize the benefits of Earth science data.
The purpose of the EPA Gulf of Mexico Modeling and Monitoring project is to provide the scientific basis to guide a reduction in the frequency, duration, size, and degree of oxygen depletion in the northern Gulf of Mexico as outlined in the recently released Hypoxia Action Plan.
