USDA UV- B Network site at the Jornada. This network was established in 1. Jornada is one of the original sites. The program's primary objective is continued operation of the 3. UV- B monitoring instruments to deliver high quality data, data products, and services in support of agricultural research describing the geographic distribution of UV- B solar irradiance, effects of increased or diminished UV- B on crops, native and invasive plants, and animals, and to facilitate the use of these measurements directly or as input to climate and crop models. Data is collected automatically every night, processed for quality control, and made available typically within one day of collection. Find data at http: //uvb. USDA UV- B Monitoring and Research Program. Progress 0. 7/0. 1/0. Outputs. OUTPUTS: The program's primary objective is continued operation of the 3. UVB monitoring instruments to deliver high quality data, data products and services in support of agricultural research describing the geographic distribution of UVB solar irradiance, effects of increased or diminished UVB on crops, native and invasive plants and animals, and to facilitate the use of these measurements directly or as input to climate and crop models. Agriculture is entering a critical period with regard to climate change, crop stress and potential related impact to crop productivity. The UVMRP provides accurate UVB data available freely on the web.
![]() The program works with agricultural and forest researchers to evaluate the effects of UVB and other climate stressors on crops, livestock and forest and range resources sustainability. Decision makers need reliable and relevant crop yield and economic assessment tools. To meet this particular need UVMRP is completing development of an agricultural impact model that will couple satellite and in- situ observations of climate, solar radiation and a wide range of stressors with existing comprehensive crop growth models and economic analyses. Some research results of the program were presented in international scientific conferences and published in referred journals. Continued development, research and data dissemination are being provided for a program consisting of a regional status- and- trends network of 3. UVB and visible radiometers to provide data to determine climatology and trends and to support aerosol studies. ![]() An Application of Centralized Architecture. USDA UV-B monitoring system: An application of centralized. George Janson, Bill Durham, Roger Tree, Rita Deike USDA UV-B Monitoring and Research Program. Currently the emphasis is on instrument calibration; data management; QA/QC procedures and protocols; establishing comparability with other monitoring programs in the U. S. Research is being conducted to determine the influence of clouds, aerosols and ozone on surface UVB irradiance. Enhanced UVB radiation generally has negative impacts on growth, yield and quality of some crop plants such as soybean, winter wheat, rice, sorghum, cotton and corn. A wide range of research problems regarding UV impact and other climate stress factors (moisture, temperature, soil nutrients, and CO2) on agriculture and ecosystems have been addressed by the program. The program facilitates research: 1) to quantify phenomenological, growth and physiological parameters of crop plants as affected by UV- B radiation in interaction with other environmental factors in growth chambers, green houses and fields, 2) to provide knowledge that will aid in identifying heat and UVB- sensitive parameters of crop plants that can be manipulated by plant breeders to develop cultivars better suited to high- temperature and higher UVB radiation environments, and 3) to provide quantitative functional algorithms needed to improve crop simulation models, which in turn can be used for climate change impact analysis across the nation to assist in crop management decisions for producers and economic and policy decisions for resource mangers.

High quality data continues to be collected from the 3. UV- wavelength instruments. Data collected by UVMRP is being used for agricultural response to UVB research performed at such places as Mississippi State University and the University of Illinois Urbana- Champaign. Data is also being used by health researchers at the University of California Davis and the University of Hawaii Manoa. Students routinely download data for science projects through our web site. Development of in- house calibration procedures for the UV shadowband instruments is underway to compensate for the closing of NOAA's Central UV Calibration Facility. Similar procedures for the other primary instruments will begin once the UV procedures are vetted and accepted by the scientific community. UVMRP's web site enhancements, in response to user requests, allow the user greater ability to define the download parameters without needing UVMRP staff to assist especially for requests that span the 1. Additional data products available are map- based presentations of the data and the ability to choose the type and level of calibration applied to the data. This web interface is the primary venue for disseminating UVMRP data and data products. The data is collected automatically every night, processed for quality control and made available on the web site, typically within one day of its collection. Most data is available back through 1. The UVMRP staff traveled to present status and preliminary results of UVMRP's numerical modeling/simulation and radiation effects research using ultraviolet ground and space- based measurements at national/annual scientific meetings, the American Geophysical Union (AGU), American Meteorological Society (AMS), the American Society of Agronomy (ASA), and International Society for Optical Engineering (SPIE). The staff used these opportunities to communicate and collaborate with other federal agency researchers (USDA, NOAA, NASA, EPA, NSF, USFS, and Canadian- AES). A yearly trip to Washington, DC, was taken to meet with senior supervisory personnel at USDA CSREES. Wei Gao worked with Springer- Verlag and Tsinghua publication editors to finalize a manuscript for production of the . Gao is an editor and a contributing author for this book. There are 1. 8 chapters including review chapters from renowned scientists in research fields of UV radiation, meteorology, environment and ecosystems. DEVELOPMENT AND MANAGEMENT OF A USDA UVB.
