The Advanced Microwave Scanning Radiometer-Earth Observing System (AMSR-E) is a passive microwave radiometer on board the National Aeronautics Space Agency (NASA) Earth Observing System (EOS) Aqua satellite. Aqua, a sun-synchronous polar orbiting platform, is one of a series of spacecraft launched by NASA's Earth Science Enterprise to obtain remotely-sensed data for the advancement of Earth System Science.
The AMSR-E measures passive microwave radiation, allowing for derivation of many parameters, including soil moisture, sea surface temperatures, rain rate, snow cover and sea ice extent. The instrument provides improved spatial resolution compared to earlier generations of spacecraft-borne passive microwave instruments (e.g., SMMR and SSM/I) and retrieves information in more frequencies of the microwave spectrum than its predecessors.
Data products are archived and distributed by the National Snow and Ice Data Center (NSIDC) Distributed Active Archive Center (DAAC) at the University of Colorado, Boulder (www.nsidc.org/daac/amsr/). This paper summarizes the AMSR-E data sets that will be available at NSIDC and discusses research applications of some of them.

EOSDIS, the data and information system being developed by NASA to support interdisciplinary earth science research into the 21st century, will do more than manage and distribute data from EOS-era satellites. It will also promote the exchange of data, tools, and research results across disciplinary, agency, and national boundaries. This paper describes the options that data providers will have for interacting with the EOSDIS Core System (ECS), the infrastructure of EOSDIS. The options include: using the ECS advertising service to announce the availability of data at the provider's site; submitting a candidate data set to one of the Distributed Active Archive Centers (DAACs); establishing a data server that will make the data accessible via ECS and establishing Local Information Manager (LIM) which would make the data available for multi-site searches. One additional option is through custom gateway interfaces which would provide access to existing data archives. The gateway, data server, and LIM options require the implementation of ECS code at the provider site to insure proper protocols. The advertisement and ingest options require no part of ECS design to reside at the provider site.
