The time series consists of daily total ozone values measured in the vicinity of Hyderabad, India, New York City and the Japanese Antarctic station, Syowa. Each time series encompasses a single year of data so as to approximate the condition of stationarity. The years chosen were 1979 and 1985, corresponding to those of maximum and minimum solar activity respectively. Results indicate that the spectra are dominated by sharp responses which are close to integer multiples of a 27 day cycle. Long range order is evident for those distributions occuring in the mid-latitude regions.

Two approaches were adopted, one focused on facilitating use of the data and the other on facilitating access to the data. An automated system was developed to operationally convert selected GDAAC data into GIS formats and to distribute the GIS-compatible data to a network of Remote Sensing Information Partners. The second approach provides online, interactive capabilities for GIS data searching, visualization, mapping, and analysis; access to ancillary data; and retrieval of data (in various formats) or results of analysis of the data. Specific ongoing efforts include a WebGIS, a WMT-DODS (Web Mapping Testbed-Distributed Oceanographic Data System) server, and an Open GIS Consortium (OGC)-compliant client. These related capabilities could be variously integrated into coherent, application-driven, interoperable, data access systems, which will allow a much larger and more diverse user community to make use of GDAAC data, greatly increase the information density of the data accessed by users, and enable a greater diversity of potential applications of GDAAC data

He has provided invited testimony to the U.S. House Science Committee on the status of tsunami preparedness, managed development of the Central Cascades Volcano Coordination Plan, and coordinated the public release of the Mt. Hood Volcano Coordination Plan. Wilson has also served as Earthquake Policy Analyst for the City of Berkeley, Earthquake Program Coordinator for the City of Oakland, Knowledge Management Consultant for Risk Management Solutions and was a disaster reservist in community education and outreach for several FEMA regions. He received his M. A. in Geography with a Research Emphasis on Earthquake Risk Perception of Vulnerable Populations and has a B. A. in Film, both from San Francisco State University. Hugo Yepes is a seismologist with a graduate degree from Saint Louis University (Missouri) with 25 years of experience in geological hazards evaluation and risk mitigation. His principal area of expertise is the development of early warning systems, specifically the implementation of seismic and volcanic monitoring networks, the elaboration of earthquake and eruption damage scenarios, as well as scenarios of the resulting impact on society. He is a specialist in quick response to seismic and volcanic crises, especially in their scientific evaluation and communication to the public.

Approximately 40 higher level science standard products are being produced from the Moderate Resolution Imaging Spectroradiometer (MODIS) high resolution radiances. MODIS data starting November 1, 2000 to the present have been processed with an improved calibration algorithm (version-3) and data products are available to the public and science user community. Nearly all of these products have been evaluated and found useful for science and various applications. Radiometric calibrated and geolocated radiance data and all derived atmospheric, land and ocean products are available free from NASA's Distributed Active Archive Centers (DAACs).
