Aerosol Optical Depth from Aerostat for a dust storm in the Arabian Gulf on 11 Mar 2012. The map is merged from several MODIS AOD datasets (both dark-target, ocean and land, as well as Deep Blue), filtered by quality control criteria and bias adjusted relative to Aeronet.

AeroStat: Online Platform for the Statistical Intercomparison of Aerosols [04/03/2012]

06.12.2012
AeroStat was proposed to address the challenges of intercomparison of aerosol datasets, which include disparities in spatial coverage, spatial consistency, temporal consistency, diurnal coverage and sensitivity to a variety of observing conditions. AeroStat also addresses the challenge of using multiple datasets to get a complete picture of aerosol phenomena, such as dust storms. To these ends, AeroStat provides an online environment for convenient access to: satellite and ground-based aerosol data; quality information and provenance; and Calibration and validation data. It also provides multi-sensor services, including multi-sensor intercomparison, cross-sensor bias assessment and adjustment, and maps of merged Level 2 data. It is linked to a collaborative environment, gSocial for aerosol researchers to share ideas, workflows and results. Aerostat was successfully completed and released to the user community in March 2012 at http://giovanni.gsfc.nasa.gov/aerostat/.

Scientific Software and Test Driven Development [06/05/2012]

06.05.2012
While test driven development (TDD) is gaining wide acceptance in many professional software communities, numerical algorithms present several unique challenges that have cast some doubt on the relevance of the methodology to the development of scientific software. Such concerns range from the need for reliable error estimates for roundoff and truncation errors to the general lack of known analytic solutions for codes designed for fundamental research. Fortunately, approaches can be found that minimize and/or circumvent these issues.

Monitoring Riparian Buffer Zones along the Tar River Basin using EOS Land Products [08/02/2011]

09.14.2011
Riparian buffer zones are vital to the ecological and biological health of watershed ecosystems. This project focused on a 26,000 km2 region of North Carolina, USA, including the Tar River. We acquired MODIS Collection V005 1.0km retrievals of LST, LAI, and GPP over the Upper Tar River study area and created 30m change detection composites from surface reflectance datasets obtained from the Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS). Using ENVI and ArcGIS software, we then combined the satellite datasets with the North Carolina streams GIS Layer to monitor changes in the riparian buffer zone over a 10 year period (2000-2010). As a result of this research, which is planned to continue at least through 2013, the citizens of North Carolina will have access to new information and analysis that will provide insights into the state’s ongoing monitoring of the ecological functioning and biodiversity of the Tar River watershed.

Seasonal Influenza Dependency on Environmental and Meteorological Parameters [08/02/2011]

09.14.2011
Influenza has affected the human race at least since the beginning of the written history. The earliest recorded influenza epidemic appears to be in 412 B.C. by Hippocrates, the Greek physician who is considered the father of western medicine. Influenza appears every year and almost everyone has had influenza one time or another. Although it is the most common disease, influenza inflicts considerable loss of human lives and productivity in societies each year. In each annual influenza epidemic, it is estimated that 5-15% of the populations are infected. For the U.S. alone, the annual economic cost may exceed $167 Billion.

Introduction to Office Ergonomics [09/06/2011]

09.09.2011
Ergonomics (or human factors) is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance. In short, ergonomics is the science of fitting the workplace, furniture, tasks, tools and equipment to the worker.

Characterization of Aerosol Data Quality from MODIS for Coastal Regions [08/02/2011]

09.09.2011
Characterization of Aerosol Data Quality from MODIS for Coastal Regions, by Jacob Anderson of U. Nebraska--Lincoln. Summer intern Jacob Anderson characterized biases of MODIS aerosols relative to coastal Aeronet stations. Coastal sites can register MODIS aerosols computed with either the oceanic or land-based MODIS "dark-target" algorithms. In general, Land algorithm performs better than the Over-Ocean algorithm for coastal sites, with the disparity increasing as site location moves inland.
