The Atmospheric Sciences Data Center (ASDC) at NASA Langley Research Center archives data from several projects that can be used for studying aerosols, gases, and clouds in urban, regional and global scale environments. Sample measurements from four data products will be shown for the region surrounding Hong Kong.

Clouds and the Earth's Radiant Energy System (CERES) data products contain aerosol and cloud measurements from regional and global scale environments. The spatial resolution is 20 kilometers at nadir for the Terra and Aqua satellites.

Multi-angle Imaging SpectroRadiometer (MISR) data products contain aerosol and cloud measurements from regional and global scale environments. MISR data are collected using nine cameras, at four different angles and four wavelengths (red, blue, green, near-infrared). The spatial resolution is from 275 to 1100 meters.

Measurements Of Pollution In The Troposphere (MOPITT) data products contain profiles of carbon monoxide and total column methane measurements for a global scale environment. The spatial resolution is 22 km horizontally and 4 km vertically. The swath width is approximately 640km.

Global Tropospheric Experiment (GTE) data products contain measurements of many gases from urban and regional environments. The spatial resolution varies for each field campaign. Data from the TRACE-P field campaign will be highlighted.

All of these data are available from the NASA Langley ASDC at http://eosweb.nasa.gov.
