Climate Drivers Team

Imtiaz Rangwala

Lead - Climate Drivers Team

Dr. Rangwala is a research scientist at the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder and NOAA’s Physical Sciences Division. He is a climate scientist with training in assessing and diagnosing regional scale climate change. Using climate observations and models, he works to understand and quantify climate processes relevant to regional warming trends and hydrological processes changes. This specifically ties into understanding climate extremes and changes in water balance in the western U.S., including the Great Plains region, and the how these extremes affect ecosystem response. Other work includes future climate change uncertainty in the context of decision-making and climate adaptation. He has extensive experience in the development and communication of useful and usable future climate change scenarios for natural resource management. Dr. Rangwala also has expertise on climate change in high elevation regions - his work in the past has focused on the Colorado Rocky Mountains and the Tibetan Plateau. He is also part of a global community of scientists focused on examining the issue of elevation-dependent climate change in mountain regions.

Candida Dewes

Research Scientist - Climate Drivers Team
Candida Dewes

Dr. Dewes is a Research Scientist at NOAA’s Physical Sciences Division and CIRES/Western Water Assessment at the University of Colorado Boulder. She has extensive research experience in climate variability and climate change and their impacts on socio-ecological systems. Her research with the North Central Climate Science Center focuses on regional-scale land surface processes contributing to drought, and in particular, the variability of evaporative demand under climate change. She is also interested in the role of rain versus snow in mountainous terrain how these precipitation types impact regional water resources. Before joining the NC CSC, Dr. Dewes was a postdoc at the University of Virginia and Visiting Scholar at the National Center for Atmospheric Research, where she explored the climate impacts of land cover changes using NCAR’s Community Land Model (CLM). As a grad student at University of California, Santa Barbara, she investigated climate trends in Mexico and the impacts of climate variability on Mexican agriculture.

Research Scientist (CIRES), Climate Drivers FSA Collaborator/Advisor
Joe Barsugli

Joe Barsugli is a research scientist at the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder (CU) and at the Western Water Assessment (WWA), a joint effort between NOAA and CU. Trained in climate theory and modeling, he works at the technical interface connecting climate science with the practitioners and technical staff who inform water and land management planning in Colorado - his work connects researchers to the problems faced by managers.

Mike Hobbins

Research Scientist (CIRES), Climate Drivers FSA Collaborator/Advisor
Mike Hobbins

Mike Hobbins is a Research Scientist with the Cooperative Institute for Research in Environmental Sciences (CIRES) at NOAA’s Physical Sciences Division in Boulder, Colorado. A hydrologist by training, he received his Bachelors at the University of Leeds (UK) and his doctorate from Colorado State University. His research interests lie in land-atmosphere relations and the regional-scale interactions of evapotranspiration, evaporative demand, and drought, particularly in understanding the dynamics of the coupled system but also unlocking their potential to provide early warning and forecasts of drought. He developed the Evaporative Demand Drought Index (EDDI, available on the WWA Dashboard) and works at various timescales, from past inter-decadal trends through the current drivers of variability to predictions at short-term, seasonal, and climate scales. His drought-monitoring and early warning development work covers the continental U.S. for the National Integrated Drought Information System (NIDIS) and food-insecure countries around the globe for the Famine Early Warning System Network (FEWS NET).

Sanjiv Kumar

Research Associate (NOAA ESRL Physical Sciences Division), Climate Drivers FSA Collaborator/Advisor
Sanjiv Kumar

Sanjiv Kumar is a NRC Research Associate at NOAA Earth Systems Research Laboratory Physical Science Division, Boulder Colorado. He conducts climate modeling experiments to better understand the roles of land processes and their coupled atmospheric interactions in improving soil moisture predictability at inter-seasonal to decadal time scales. He also employs observations and re-analysis data in his research. His current research also includes clarifying the role of internal climate variability in regional hydroclimatic variability and change by employing advanced statistical techniques and large ensemble climate simulations. Sanjiv earned his PhD in hydroclimatology from the School of Civil Engineering at Purdue University in 2011. He completed his postdoctoral training at the Center for Ocean-Land-Atmosphere Studies in Virginia and the National Center for Atmospheric Research in Colorado from 2011 to 2014. He was a Research Associate at the Pacific Climate Impacts Consortium at the University of Victoria, Canada, prior to joining NOAA ESRL in August 2015. See publications on his Google Scholar profile

Jeff Lukas

Research Integration Specialist (WWA), Climate Drivers FSA Collaborator/Advisor
Jeff Lukas

Jeff Lukas is a Research Integration Specialist with the Western Water Assessment (WWA) program at CIRES, based out of the University of Colorado Boulder. For the past 15 years, Jeff has worked closely with water managers and other resource decision-makers in the Rocky Mountain West to help them understand and prepare for climate-related vulnerabilities by interpreting and applying paleoclimate data, historical climate records, and climate projections. He was lead author of the 2014 Climate Change in Colorado report for the Colorado Water Conservation Board, which summarized the latest science on climate trends and projections for the state. Jeff was initially trained in forest ecology (M.S., Forestry, University of Montana) and conducted fire history research, later shifting into applied climatology and hydrology.

Daniel McEvoy

Daniel McEvoy is a researcher with the Western Regional Climate Center. His research interests are interdisciplinary and span the fields of climate, hydrology, and meteorology. They include advancing drought monitoring technology, seasonal drought prediction, the role of evaporative demand on drought, quality and uncertainty assessment of weather observations, and climate modeling. 

Jared Oyler

Postdoctoral Scholar (Network for Sustainable Climate Risk Management), Climate Drivers FSA Collaborator/Advisor
Jared Oyler

Jared Oyler is a postdoctoral scholar within the Network for Sustainable Climate Risk Management (SCRiM) at Penn State. He is the project lead for the TopoWx conterminous U.S. temperature product and develops gridded and downscaled climate data products and statistical models for use in natural resource management, agriculture, environmental research and decision support applications. He holds a PhD in Forestry and Conservation from the University of Montana, an MS in Geography from Penn State, and a BS in Computer Information Systems from Drexel University.

Gabriel Senay is co-located at the DOI North Central Climate Science Center (NC CSC) starting August 2014. His research work focuses on the integration and application of remotely sensed data for agro-hydrologic modeling. Gabriel will promote and advance the use of satellite-derived multi-scale evapotranspiration products by the key stakeholders in the irrigation community for water resources planning and management. He will establish a stronger linkage between the USGS Earth Resources Observation and Science (EROS) Center Land Cover Monitoring, Assessment and Projection (LCMAP) program and the NC CSC Resource for Vulnerability Assessment, Adaptation and Mitigation Planning activities in order to improve data and information products for climate and land use research and applications.
