May 2017- Dr. Xin-Zhong Liang will be visiting for two weeks beginning April 17. He will be discussing current research and the status of the climate-crop modeling system with our staff and other CSU faculty. Welcome Dr. Liang.

Congratulations to our Office Manger Rita Deike for receiving the 2017 Outstanding Achievement Award. The award recognizes meritorious and outstanding achievement in their job and service to the university. Rita has been with the USDA UV-B Monitoring and Research Program since 2004, and with Colorado State University since 1986.

April 2017- Our research paper, Determining climate effects on US total agricultural productivity, Xin-Zhong Liang, You Wu, Robert G. Chambers, Daniel L. Schmoldt, Wei Gao, Chaoshun Liu, Yan-An Liu, Chao Sun, and Jennifer A. Kennedy has been published in PNAS (Proceedings of the National Academy of Sciences). It will also be featured in Nature's Research Highlights. The study finds that the United States agricultural economy is becoming increasingly sensitive to the climate. We compared 1948-2011 climate variables in specific United States regions to a measure of agricultural efficiency referred to as total factor productivity (TFP), which is the ratio of agricultural outputs per production input. TFP fluctuations were larger and were more tightly correlated with climate variations from 1981-2010 compared to 1951-1980. A regression model suggests that seasonal and regional temperature and precipitation fluctuations explain almost 50% of TFP growth variation from 1951-1980 and approximately 70% of TFP growth variation from 1981-2010. These findings suggest that agricultural productivity has become more sensitive to climate since 1980. Base on current climate projections under medium to high emissions scenarios, this could cause TFP to decrease by an average of 2.84%- 4.34% per year; in either case, TFP would fall to pre-1980 levels by 2050, despite accounting for present rates of innovation. The research was funded by the US Department of Agriculture (USDA) UV-B Monitoring and Research Program, Colorado State University, under Grant USDA National Institute of Food and Agriculture Projects 2013-34263-20931, 2014-34263-22038, and 2015-34263-24070.

January 2015 - In mid-December the climatological monitoring station at Big Bend National Park was relocated from Castolon to K-Bar, with a consequent renaming from TX01\TX02 to TX61\TX62. Primary reason for the move was due to persistent telephone line and power problems at the Castolon site over the past two years, which were caused by nearby construction activity which had repeatedly dug up and damaged those cables. Efforts over the subsequent years to repair these lines were ineffective, necessitating frequent visits by the NPS physical science technicians. Adding to the frustration was the remoteness of this site and the understaffing the Park was experiencing, such that their site visits were infrequent and of short duration. UVMRP technicians also visited the site to assist with troubleshooting and installation of 'temporary' work-arounds. Overall, these problems created significant gaps in the data and UVMRP staff made the decision to relocate our instruments to K-Bar, which is Big Bend NP's primary environmental monitoring location, is considerably easier to access and is visited at least weekly.

Our program hosted a visit of the NREL’s External Advisory Committee (EAC) on Wednesday, November 19.

We have had all these lifeless pieces sitting on our lab bench for so long, now George has put them together and made them working, and they are finally coming to life. Now we can expand our research collaboration to the outdoor, to investigate how urban forest filters UV radiation? How much UV radiation can forest intercept? How differences in species, forest coverage, leaf area index can affect UV radiation on the ground? And how we can link this to outdoor recreation and to human health, such as UV induced skin diseases, etc.? Now we can start to explore these questions and begin to look for collaborative research funding.” Read the full story.
