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. Wei Gao, Dr Zhibin Sun, Dr. Shinichi Asao and Maosi Chen will be attending the SPIE Remote Sensing and Modeling of Ecosystem for Sustainability conference in San Diego, CA from August 9 - 13, 2015. Dr. Sun will present a paper titled Combined UV Irradiance from TOMS-OMI satellite and UVMRP ground measurements across the continental U.S.. Dr. Asao will present Effects of bias in solar radiation inputs on ecosystem model performance and Maosi Chen will present Two-stage reference channel calibration for collocated UV and VIS Multi-Filter Rotating Shadowband Radiometers.

Two students from Southern University and Agricultural and Mechanical Collge, Baton Rouge, Louisiana are visiting for the month of July. The focus of their research has been how urban forest influences UV radiation in an urban environment and how UV radiation affects a tree's health. We are helping them learn about our instrumentation and data processing procedures. 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 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.
