An Ultraviolet Radiation Monitoring and Research Program for Agriculture

摘要: The United States Department of Agriculture (USDA) Ultraviolet-B Monitoring and Research Program (UVMRP) was initiated in 1992 through a grant to Colorado State University (Fort Collins, CO, USA), authorized by Congress under the USDA Cooperative Education Extension Service (CSREES) Special Grant authority, provide agricultural science research community with information necessary determine if changing levels UV-B radiation would threaten food fiber production States. UVMRP consists three major components: (1) monitoring solar an emphasis on radiation; (2) effects UV specific plants crops; (3) crop growth assessment modeling assess impact climate change scenarios production. network, consisting visible measurement instrumentation installed at 37 climatological sites, is described this chapter, along basic algorithms used process data calibration methods designed accurate long term records. Procedures developed aerosol optical depth, columnar ozone, enhanced products, such as integrated irradiances weighted biological spectral weighting functions summed over selected time periods, are also described. An updated, flexible web page interface that allows users access various products documented. UVMRP’s role studies summarized, including contributions scientists several collaborating universities. component models sustainability coupling state forecasting model order obtain yield introduced. Future directions presented.
