The image shown to the left is one of our climatological sites that constitute the UV radiation monitoring network within the USDA UV-B Monitoring and Research Program. Each site has a suite of instruments that measure downwelling radiation in various agriculturally important regions between 280 and 1040 nanometers. Detailed information about each instrument and each location can be found under the above Monitoring Network link.

Dr. Xin-Zhong Liang from University of Maryland will be visiting us on July 7, along with Dr. Min Xu who will be visiting us for the week of July 7. Dr. Min Xu will collaborate with staff on the climate-crop modeling component of our Program. He will be assisting with incorporating ground-based UV data into the CWRF model, assimilating satellite cloud products and adding satellite-based soil moisture data in the assimilation to improve the performance of the CWRF seasonal forecast.

A new publication is available from 2014, published in Photosynthetica titled Maize growth and developmental responses to temperature and ultraviolet-B radiation interaction. Please see our Research Publications link.

We would like to welcome our new research scientist Dr. Zhibin Sun. Dr. Sun received his PhD from University of Maryland in August 2007. He has extensive knowledge of data assimilation theories and algorithm development. He will be helping us establish confidence in the extrapolation of data collected at our sites to the surrounding regions. Welcome.

Introduction

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 impact 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, as well as assimilating satellite and in situ observations to study climate-crop interactions and related economic impacts stemming from crop response to a wide range of stressors, including temperature, moisture, nutrient, 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 over wide geographic areas of 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 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.

The data is collected automatically every night, processed for quality control, and made available on this web site, typically within one day of its collection. Most data is 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.
