Over the history of remotesensing, the complexity and volume of data sets have increased unremittingly. The complexity of the data sets has led to the need for more descriptive metadata. The volume, resulting from both increased precision and range in the data sets, has led to the need for efficient data and portable handling techniques. Further, the precision calls for greater detail in describing and documenting the manner in which the data was collected and calibrated. This paper describes one view of the optimal product design for NPOESS requirements.

Lessons learned from the implementation, operation, and science processing from a number of successful NASA LaRC remotesensing experiments will be presented. Despite good flight heritage, well-known designs, and known data retrieval algorithms these experiments remain challenging. The authors will summarize common lessons learned from different project phases and discuss these lessons in the context of planned and future missions with emphasis on improving Level 1 data quality.

Hyperspectral data and products derived from instrumentation such as the atmospheric Infrared Sounder (AIRS), the Cross-track Infrared Sounder (CrIS), Geosynchronous Imaging Fourier Transform Spectrometer (GIFTS) and the GOES-R Hyperspectral environmental Suite (HES) will impose storage and data retrieval requirements that far exceed the demands of earlier generation remotesensing instrumentation used for atmospheric science research. A new architecture designed to address projected real time and research needs is undergoing prototype design and development. The system is designed using proven aspects of distributed data storage networks, descriptive metadata associated with stored files, data cataloging and database search schemes, and a data delivery approach that obeys accepted standards. Preliminary implementation and testing of some components of this architecture indicate that the design approach shows promise of an improved method for storage and library functionality for the data volumes associated with operational hyperspectral instrumentation.

In earlier work (2), NOAA's Coastal Service Center in Charleston, S.C. reviewed current remotesensing and took a broader look at that technology applied to coastal resource management. They found 25 application areas and grouped them into 5 broader categories. In this paper we will explain some background and complexity of remotesensing when imaging in shallow water. This region is more complex than the deep ocean but there is synergy or opportunity to combine remotesensing measurements. Then we will summarize the 25 coastal areas of application with regard to spatial, spectral and temporal remotesensing needs including use of potential hyper-spectral sensors. Finally, we use the example of coral reef observations to explain the difficulty in trying to set remotesensing operational rules.

Three semi-autonomous atmosphericsensing systems were installed in the tropical western Pacific region. The first of these atmospheric Radiation and Cloud Stations (ARCS) began operation in 1996. Each ARCS is configured as a system-of-systems since it comprises an ensemble of independent instrument systems. The ARCS collect, process, and transmit large volumes of cloud, solar and thermal radiation, and meteorological data to support climate studies and climate-modeling improvements as part of the U.S. Department of Energy's atmospheric and Radiation Measurement (ARM) Program. data from these tropical ARCS stations have been used for satellite ground-truth data comparisons and validations, including comparisons for MTI and AQUA satellite data. Our experiences with these systems in the tropics led to modifications in their design. An ongoing international logistics effort is required to keep gigabytes per day of quality-assured data flowing to the ARM program's archives. Design criteria, performance, communications methods, and the day-to-day logistics required to support long-term operations of ground-based remoteatmosphericsensing systems are discussed. End-to-end data flow from the ARCS systems to the ARM Program archives is discussed.

Five years of rainfall data from the Tropical Rainfall Measuring Mission are now available for use. This paper surveys comparisons of these rain rate data with buoy-based estimates over the Tropical Pacific and with simulations with the CCM3, a general circulation model of atmospheric circulation. We examine both the seasonal and diurnal cycles in the data. The TRMM data agree reasonably well with the buoy data for both the seasonal and diurnal cycles. While the data generally agree with the simulations, there are some discrepancies which can be attributed to model failures.

We review the advantages of a national standard for microwave brightness temperature and outline our proposed approach toward developing such a standard. The proposal is a combined standard that would comprise both a standard radiometer, traceable to primary noise standards, and a fully characterized standard target. We also review our recent work on development of a standard radiometer and on characterization of calibration targets.

The Virtual Laboratory for Education and Training in Satellite Matters (VL) was established to maximize the exploitation of meteorological satellite data across the globe. It is a collaborative effort joining four major operational meteorological satellite operators with six WMO "centers of excellence" for education and training in satellite meteorology. Those "centers of excellence" serve as the satellite-focused training resource for WMO Members. The VL continues to evolve and has been used successfully in a number of WMO sponsored training events since 2000.

In this paper we present regional high spatial resolution sounding products from MODIS and AIRS data processed by both stand-alone and synergistic retrieval approaches. These unique regional high spatial resolution (at sensor's single field of view) atmospheric sounding products such as temperature, total precipitable water and surface temperature can provide valuable information for regional near-real time weather monitoring and meso-scale synoptic analysis, and other local environmental applications. Performance comparison between stand-alone and fusion products will assist validation effort and lead to the refinement of processing algorithms. Synergistic utilization of MODIS and AIRS data will also demonstrate the complementary information content provided by two different sensors and will pave the way for future optimal amalgamation of imaging and sounding data.

An adjoint limited area numerical weather prediction model with multiple nests has been developed. The adjoint modeling system has the capability to pass gradient information from the finer spaced nest to the coarser spaced domain. Therefore, gradients of scalar functions calculated from small scale features can be computed with respect to the large scale model state. Sensitivity experiments were performed to show that the nested adjoint model produces physically meaningful gradients. Results from data assimilation experiments will be presented at the conference. An ad joint model such as the one presented here, could be in important tool for variational assimilation schemes that intend to make use of high resolution remotely sensed data.
