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.

We are one of eight NASA Science Mission Directorate (SMD) DAACs that offer Earth science data, information, and services to research scientists, applications scientists, applications users, and students. The GES DISC is the home (archive) of Precipitation, Atmospheric Chemistry and Dynamics, and information, as well as data and information from other related disciplines. The GES DISC is located at Goddard Space Flight Center, in Greenbelt, Maryland.
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.
A Springtime Study of Aerosol Properties and Atmospheric Chemistry over an Ice-Free Region of the Arctic
ISCCP was established as part of the World Climate Research Programme to collect and analyze satellite radiance measurements to infer the global distribution of clouds, their properties, and their diurnal, seasonal, and interannual variations. The resulting datasets and analysis products are used to improve understanding and modeling of the role of clouds in climate, with the primary focus being the elucidation of the effects of clouds on the radiation balance. The Global Processing Center for ISCCP is located at the NASA Goddard Institute for Space Studies.
The Moderate Resolution Imaging Spectroradiometer (MODIS) is an earth-viewing sensor that flies on the Earth Observing System (EOS) Terra and Aqua satellites, launched in 1999 and 2002, respectively. MODIS scans a swath width of 2330 km that is sufficiently wide to provide nearly complete global coverage every two days from a polar-orbiting, sun-synchronous, platform at an altitude of 705 km. MODIS provides images in 36 spectral channels between 0.414 and 14.235 micrometers with spatial resolutions of 250 m (two bands), 500 m (five bands) and 1000 m (29 bands).
Provide users of the MODAPS/LAADS with a variety of basic information concerning the MODIS instrument, the MODIS products, and the services available from MODAPS for the acquisition of MODIS products and production codes.
NASA's Ocean Biology Processing Group supports the collection, processing, calibration, validation, archive and distribution of ocean-related products from a number of missions which are supported within the framework and facilities of the current NASA Ocean Data Processing System (ODPS) which has been successfully supporting operational, satellite-based remote-sensing missions since 1996. The group's capabilities continue to evolve and expand to meet the demands and challenges of future missions.
Missions, data sets and activities currently supported or in development include:
SeaWiFS : 1997 - present, MODIS (Terra and Aqua) : 2000 - present, MERIS (US Coastal Waters) Feb 2009 - present , CZCS / Nimbus-7 : 1978 - 1986, OCTS / ADEOS-I : 1996 - 1997, Glory data system prototype : 2010 launch, Aquarius / SAC-D : Late 2010 launch, VIIRS / NPP : January 2011 launch, Community Processing & Analysis Software SeaDAS (1991- present)
Information and access to the complete suite of NASA ocean color data products
A Fortran testing framework utility developed by SIVO that is available to the general public through a NASA Open Source Agreement.
The Tropical Rainfall Measuring Mission (TRMM) has its own unique Precipitation Processing System (PPS) to process information from the satellite. PPS analyzes TRMM rainfall data as well as data from other Precipitation based missions and also provides validation from nearly a dozen TRMM ground radar sites.
The purpose of the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) Project is to provide quantitative data on global ocean bio-optical properties to the Earth science community. Subtle changes in ocean color signify various types and quantities of marine phytoplankton (microscopic marine plants), the knowledge of which has both scientific and practical applications. The SeaWiFS Project will develop and operate a research data system that will process, calibrate, validate, archive and distribute data received from an Earth-orbiting ocean color sensor. A detailed description of the objectives, organization and operations as well as the current status of the SeaWiFS Project is available.
SERVIR-Africa is a partnership between the SERVIR program and African institutions to extend the successful model of SERVIR operating in Mesoamerica.
The Seven SouthEast Asian Studies (7-SEAS) Mission has been established to characterize aerosol-meteorological interactions from Java through the Malay Peninsula and Southeast Asia to Taiwan. The 7-SEAS program was organized through a collaborative effort with the U.S. State Department and governments in Southeast Asia, NCAR Research Applications Laboratory, NASA Aerosol Robotic Network (AERONET) program, and the Office of Naval Research international field offices.
SORCE is a satellite mission that provides state-of-the-art measurements of incoming x-ray, ultraviolet, visible, near-infrared, and total solar radiation. The measurements provided by SORCE specifically address long-term climate change, natural variability and enhanced climate prediction, and atmospheric ozone and UV-B radiation. These measurements are critical to studies of the Sun: its effect on our Earth system, and its influence on humankind.
The NASA Aerosol Robotic Network (AERONET) will begin a four-year intensive field campaign, called TIGERZ, on April 2008 to measure aerosol microphysical and optical properties over India.
