Welcome Dr. Maosi Chen, our new Postdoctoral Research Fellow. Dr. Chen received his PhD in Ecology from Colorado State University last fall. Dr. Chen will be helping us with the monitoring and modeling aspects of our project. His interests include solar radiation transfer in the ultraviolet (UV) to near infrared regions in the atmosphere, in-situ calibration methods of ground radiometers, and solar UV impacts on plant litter decomposition. Welcome Dr. Chen.
Welcome Dr. Melina Zempila, our new Research Scientist. Dr. Zempila received her PhD in Environmental Physics from Aristotle University of Thessaloniki, Thessaloniki, Greece. Dr. Zempila brings seven years of experience in the measurement and modeling of UV and total spectrum solar energy to our program. She was instrumental in running the Greek UV NETwork and has extensive knowledge of the transfer of solar radiation in the atmosphere and the remote sensing of atmospheric parameters influencing the amount of solar radiation reaching the Earth’s surface. She was also responsible for the operation of the Hellenic Network of Solar Radiation. Dr. Zempila will focus on the atmospheric effects on the surface UV solar radiation and the procedures used to calibrate instruments deployed in the UVMRP network. Welcome Dr. Zempila.
The UV-B Monitoring and Research Program (UVMRP) is a data collection and research program of the United States Department of Agriculture (USDA), headquartered at Colorado State University in Fort Collins, Colorado.
The UVMRP supports two unique and complimentary program components:
Integrated Agricultural Impact Assessment System
Agriculture is entering a critical period with regard to climate change, crop stress, and potential related impacts to crop productivity. Decision makers need reliable and relevant crop yield and economic assessment tools. The objective of this UVMRP program component is to develop an Integrated Agricultural Impact Assessment System. This system will couple the Earth's climate, ultraviolet-visible solar radiation, and comprehensive crop growth models, and assimilating satellite and in situ observations to study climate-crop interactions and related economic impacts stemming from crop responses to a wide range of stressors. Common stressors include temperature, moisture, nutrients, UV radiation, CO2 concentration, aerosols and other air pollutants. Please click on the above Agricultural Impact for more information.
UV-B Monitoring Network
High-energy ultraviolet solar radiation can significantly damage plants, crops, animals, and ecosystems, alone or in combination with other environmental stress factors such as temperature and moisture. To address these concerns, in 1992, the USDA established the UV-B Monitoring and Research Program at Colorado State University to provide cost-effective monitoring of UV-B levels across the United States. The program's primary objective is continued operation of the national network of UV-B monitoring instruments to deliver high-quality data, data products, and services in support of agricultural research. In particular, we quantify the geographic distribution of UV-B solar irradiance; the effects of increased or diminished UV-B on crops, native and invasive plants, and animals; and facilitate the use of these measurements directly, or as inputs to climate and crop models.
These data are collected automatically every night, processed for quality control, and made available on this web site, typically within one day of its collection. Most data are available back through 1997, with some additional data available back to 1993. Please click on the above Monitoring Network for information about our locations and instruments.
